TAC B series bearings incorporate NSK’s recently developed molded polyamide resin cage. In addition, using extra-pure (EP) steel for the inner and outer rings has further enhanced service life. The axial rigidity is high because of a large number of balls and a contact angle of 60?. Compared with tapered roller bearings of cylindrical roller bearings, this type has lower starting torque; so smoother rotation is possible with less driving force.
