It is used primarily in optical and measurement equipment where high precision movement is required. STRUCTURE AND ADVANTAGES The NB slide way consists of precision ground track bases and caged rollers. Precision rollers are used as the rotating element. Since they do not recirculate, there is less frictional resistance fluctuation. Additionally, there is little or no difference between the static and dynamic frictional resistances. Suitable for Minute Motion: Because the frictional resistance is extremely small and there is little or no difference between the static and dynamic frictional resistances, the NB slide way is well suited for minute motion. It can follow minute motion accurately, resulting in highly accurate linear movement. Low-Speed Stability: Since the frictional resistance fluctuation is small even under low-load conditions, stable motion is obtained from low to high speeds. High Rigidity and High Load Capacity: Since the rollers provide a larger contact area compared with ball elements, there is less elastic deformation. Additionally, since the rollers do not recirculate, the effective number of rotating elements is large, resulting in high rigidity and high load capacity. Low Noise: The use of a roller cage prevents noise from being generated by contact between the rotating elements, resulting in quiet operation. All Stainless Type Available: The anti-corrosion SVS/SVWS slide ways have all stainless-steel components, making them ideal for use in clean room applications.

The all stainless-steel optional feature makes it suitable for use in corrosive environments. SVW Type ACCURACY AND RATED LIFE The SVW type slide way consists of two R type roller cages, two SV-type rails, and one W type rail with V- shaped grooves on both sides. The use of a W-type rail results in a compact design. The SVWS type is also available with all stainless steel components. Accuracy: The accuracy of a slide way is measured along its entire length, as illustrated in Figure H-3, and expressed in terms of parallelism. It is categorized into three levels: high grade (no suffix), precision grade (P), and highprecision grade (UP).

7 Берг АБ Тел. (49) , факс (49) NOTES ON OPERATION Pre-load Adjustment: Inaccurate pre-load adjustment may reduce the motion accuracy, resulting in skewing and shortening of slide way life. The pre-load should be adjusted carefully. Cage Slippage: When used under high-speed, unbalanced-load, or vibrational conditions, cage slippage may occur. The stroke distance should be determined with sufficient margin, and an excessive pre-load should not be applied. End Pieces: End pieces are attached to each end of the slide way to prevent removal of the cage. Do not use them as a mechanism stopper. Knock Pin Hole: When using SVW type knock pin holes to attach a slide way, the holes on the mounting surface should be machined after attaching the W type rail. After machining, remove the chips completely and wash as required. Careful Handling: Dropping a slide way may result in scratches or dents on the raceway surface, preventing smooth motion and affecting accuracy. Care should be exercised in handling. Use as a Set: The accuracy tolerance of a slide way is designed to be adjusted within a particular set of components. If components from different sets are used, accuracy may be affected.

Stroke: Figure H-11 Travel Distance When the slide way moves along the tracking base, the cage moves half the distance traveled by the slide way in the same direction. Therefore, although the applied load may be fixed on the table, the distance between the load center and cage center will change. To achieve stable accuracy, determine the stroke distance and length of the tracking base as follows: Rail length (L) When the stroke is 400 or over S L / 1. When the stroke is less than 400, S L Cage length () L - S Number of rollers (Z) -a Z = +1 p S : stroke () L : rail length () a,p : Refer to roller cage dimensions (Page H-19) Rated Load: The rated load for the slide way is obtained using the equations listed in Table H-4.

The SYBS type utilizes ball as the rolling elements. The ultra compact design contributes greatly to the creation of smaller and lighter industrial machinery and equipment of all types. Structure and Advantages NB's miniature slide table incorporates a unique integrated ball cage between the table and bed. All components have been produced with high precision machining technologies. Ultra Compact Design The table height of the SYBS type is 3. ~ 4. and the width is 6 ~ 1. This compact envelope when compared with conventional slide tables helps to realize the miniaturization of machinery and equipment. Low Friction - Low Noise Since the rolling ball elements do not re-circulate, the frictional resistance will not vary significantly resulting in smooth operation reliable high precision. Figure H-14 Structure of SYBS Type Slide Table Additionally, the caged balls greatly reduce the contact noise of the rolling elements bringing about a low-noise operation. High Accuracy The ball raceway grooves of the bed and table are processed through simultaneous precision machining resulting in minimal processing errors, and bringing about extremely smooth, precision linear movement. Stainless Steel Structure The SYBS type slide table is constructed from only stainless steel materials. This allows for use in corrosive or high temperature applications. The SYBS is a perfect component for vacuum or clean room type environments. table ball cage stopper ball bed H-38 Берг АБ bergab@ya.ru Тел. (49) , факс (49)

Machined escape grooves should be used in the corners of the shoulder (as illustrated in Figure H-18) so that the corners will not interfere with the reference corners of the bed and/or table. Table H-8 lists the recoended shoulder heights of the mounting reference planes for the opposing sides. When installing the Miniature Slide Table without providing machined escape grooves, the corner radius may be realigned as illustrated in Figure H-19.

Mount the SYBS type as illustrated in Figure H-1 only after considering the size of mounting screw, the maximum penetration depth, and the height of the bed. Make certain that the mounting screws do not interfere with the ball cage; otherwise, the accuracy and travel life of this table will be affected adversely. Special bolts are designed for SYBS type and are available from NB. Please refer to Table H-11 for dimensions of these special mounting screws. Figure H-1 Mounting Example SYBS6,8 NB mark mounting screw mounting screw SYBS1 Care should be used to prevent any interference between the ball cage and mounting screw. NB mark TOPBALL PRODUCTS SLIDE BUSH SLIDE UNIT Table H-11 Mounting Screws (Material: Stainless Steel) Unit: Figure H- Mounting Screw M (Nominal Bolt) D H Pitch L H M M M M Stopper On both ends of the SYBS Miniature Slide Table bed section, stopper screws have been attached to prevent the ball cage from escaping. Please note that the screws are designed only to prevent the ball cage from escaping and are not intended for the use as a mechanical stopper. The ball cage may become deformed on contact with the stopper and this will result in a negative affect of the accuracy and rated life of the table. Lubrication NB's Miniature Slide Table SYBS Type is supplied with an initial application of lithium soap grease and therefore is ready for iediate use. Periodic application of a similar lubricant should be necessary depending on the operating conditions. For use in clean rooms or vacuum environments, miniature slide tables without grease or with customer specified grease are available. NB also provides K Greasefor low dust generation lubricant. Please contact NB for further details. Ball Cage Displacement When a miniature slide table is operated at high speeds; when offset loads or vibrations are present, the ball cage may deviate from the nomal position. In general operating conditions this is normal and it is recoended that the table be cycled to perform maximum full stroke travel several times during operation. This will allow the ball cage to be returned to its normal central position. Pre-Load The SYBS Minearture Slide Table is prepared with only a slight positive-clearance. H-41 Берг АБ bergab@ya.ru Тел.

44 Берг АБ Тел. (49) , факс (49) The NB Gonio way consists of hardened curved tracking bases with precisely machined V-grooves and a curved roller cage with cross-rollers. Highprecision rollers are used as the rotating elements. Since the rotational elements do not recirculate, there is less friction fluctuation, resulting in a low-frictional curved motion. Suitable for Minute Motion: The frictional resistance is extremely small and there is little or no difference between the static and dynamic frictional resistance. The NB Gonio slide way is well suited for minute motion. It can follow minute motion accurately, resulting in highly accurate curved motion. The NB Gonio way is a curved SV type slide way. It is a curved motion bearing utilizing lowfriction, non-recirculating, precision cross-rollers. It is used when there is a need to change the gradient or obtain an accurate gradient angle without changing the center of rotation in high-precision optical and measurement equipment. STRUCTURE AND ADVANTAGES Figure H-3 Structure of RV Type Gonio Way High Rigidity and High Load Capacity: The rollers provide a larger contact area than ball elements and there is less elastic deformation. Additionally, since the rollers do not recirculate, the effective number of rotating elements is larger, resulting in high rigidity and high load capacity. Ease of Assembly and Installation: The rollers are retained inside a curved roller cage, allowing assembly, installation, and the handling of components simplified. A set of components consists of 4 curved tracking bases, curved roller cages, and 8 end pieces. It can be assembled iediately. Low Noise: The use of a roller cage prevents noise from being generated by contact between the rotating elements, resulting in quiet operation. rail end piece curved roller cage H-44 Берг АБ bergab@ya.ru Тел.

Periodic application of a similar type grease is recoended depending on the operating conditions. Cage Slippage: When used under high speeds, or unbalanced loads, or when vibration condition are present, the roller cage slippage may occur. The rotation range should be determined with a sufficient margin, and an excessive pre-load should not be applied. Dust Prevention: Dust and foreign particles can affect the accuracy and life of a Gonio slide way. A table used in a hostile environment should be protected with a cover. Operating Temperature: The operating temperature should be kept between - 0 o C and 110 o C. Pre-load Adjustment: Inaccurate pre-load adjustment will reduce the motion accuracy, resulting in skewing and shortening life. Careful adjustment is a requirement. End Pieces: End pieces are attached to each end of the rail to prevent removal of the cage. Do not use them as a mechanical stopper. Careful Handling: Dropping a Gonio slide way may result in scratches or dents on the raceway surfaces, preventing smooth motion and affecting accuracy. Care should be exercised in handling. Use as a Set: The accuracy tolerance of a Gonio slide way is designed to be adjusted within a particular set of components. If components from different sets are used, the accuracy may be affected. SPECIAL REQUIREMENTS NB can fabricate Gonio slide ways to meet special requirements, including slide ways with non-standard roller sizes, curved tracking base lengths, rotation center diameters, rotation ranges, and number of rollers.
