Use of neele bearings ensures linear contact with the inner an outer rings, an provies excellent resistance against heavy raial or impact loas. haracterize by overall compact configuration an high rigiity, this prouct is ieal for use on all types of lathes incluing N an copying lathes. 2) Extra precision These high-precision proucts come in all sizes for workpieces ranging from those requiring only rough turning to those requiring high precision turning. ) Superb waterproof (ustproof) performance ll moels are waterproof (ustproof). s an the rear gap metho are use for low spees, whereas rotating outer ring labyrinth seals (patent pening) are employe for meium an high spees. ) Excellent wear resistance an urability The point is mae of bearing steel featuring superb wear resistance, an the prouct incluing the core portion is harene to the same harness (Rockwell 0 to ) as that of the bearing. It can be regroun as often as you want. Grease is an important factor in etermining the urability of the center. n aequate amount of special grease is use that conforms with the type an size of the prouct. Furthermore, to protect against tip wear, various moels are available: a smoothly rotating high RP, waterproof moel (oel F) that synchronize high-spee startup, an moels equippe with carbie tips (oels S an FP). ow friction High spee S F oa WP Waterproof The above sketch provies a rough guie when selecting oels F, S (S) an WP base on performance an features.
