NACHI Ball Screw Support Bearing 40TAB07DUP4, Duplex, Flush Ground, 40MM Bore, 72MM OD

Features These bearings are designed to support ball screws that are used as actuators of high precision and high speed machines Their stiffness is much greater than conventional angular contact ball bearings as these have a greater number of balls These bearings are supplied with a pre-set preload to eliminate complicated adjustment and torque measurement Flush ground bearings (suffix DU or U) can be used in DB (back to back), DF (face to face) or DT (tandem) assembly NOTE - Load Ratings When single flush ground bearing (suffix U) is assembled in duplex and axial load is applied to 2 ...

NACHI 5203, Double Row Angular Contact Bearing, Open, 17MM Bore x 40MM OD x 17.5MM W Double Row Angular Contact Ball Bearings are functionally same as two single row angular contact ball bearings mounted back-to-back except they have only one inner ring and one outer ring. These bearings take heavy radial loads, and axial loads equally in either direction.

NACHI 5208-2NS, Double Row Angular Contact Bearing, Double Sealed, 40MM Bore x 80MM OD x 30.2MM W Double Row Angular Contact Ball Bearings are functionally same as two single row angular contact ball bearings mounted back-to-back except they have only one inner ring and one outer ring. These bearings take heavy radial loads, and axial loads equally in either direction.

NACHI Features Two single row angular contact ball bearings (15° contact angle P4) are assembled to provide a high degree of rigidity in both radial & axial directions These Universal Flush Ground bearings can be mounted in DB, DF or DT Meets the needs of machine tool manufacturers for precision These bearings function at lowest possible temperature for wide range of speeds & operating loads

NACHI Features Capable of supporting radial & axial loads in one direction 2 Bearings are used in a duplex pair to provide high degree of rigidity in both radial & axial directions Meets the needs of tool manufacturers for precision (15° contact angle, P4) These bearings function at lowest possible temperature for wide range of speeds & operating loads Universal Flush
