NACHI Super Precision Bearing 7210CYDUP4, Universal Ground, Duplex, 50MM Bore, 90MM OD

NACHI 5308, Double Row Angular Contact Bearing, Open, 40MM Bore x 90MM OD x 36.5MM 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.

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 5218, Double Row Angular Contact Bearing, Open, 90MM Bore x 160MM OD x 52.4MM 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 5210ZZ, Double Row Angular Contact Bearing, Double Shielded, 50MM Bore x 90MM 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.
