NSK 45TAC75B ball screw support bearing

High precision angular contact thrust ball bearings to support precision ball screws, have better performance than earlier combinations of angular contact ball bearings or combinations using thrust bearings. they are especially suitable for high precision machine-tool feeding mechanisms and similar applications.
TAC B series
The axial rigidity is high because of a large number of balls and a contact angle of 60°.compared with tapered roller bearings of cylindrial roller bearings, this type has lower starting torque; so smoother rotation is possible with less driving force.
TAC B series bearings incorporate NSK's recently developed molded polyamide resin cage. In additon using extra-pure steel for the inner and outer rings has further enhanced service life. our EP steel is manufactured by controlling the amount of harmful oxide inclusions , which eliminates large size inclusions and enjoys higher purity than vaccum arc remelted(var) steel.
The series with "DG" seal, low torque contact seal, with "WPH" grease, an waterproof grease, increase the reliability and provide for easy handling.
