Bearings for Swiveling Spindle Heads used in Machine Tools NSK

img_spb_swiveling_ov

A series of angular contact ball bearings that has been designed specifically for swiveling spindle heads used in machine tools, such as machining centers and multi-tasking machine tools, and is suitable for high precision processing.

Features

  1. Ball bearings achieve high running accuracy and low torque rotation.
  2. High moment stiffness on a par with crossed roller bearings.
  3. Exclusive design of the thin cross-section profile is thinner than that of a standard angular contact ball bearing.

SINGLE ROW ANGULAR CONTACT

Single row angular contact ball bearings feature raceways with high and low shoulders. These opposing raceways are designed to carry thrust load in one direction.

DOUBLE ROW ANGULAR CONTACT

Double row angular contact ball bearings have an inner and outer ring with a double raceway. The two rows are so related that the contact angle is similar to a pair of back-to-back single row bearings.
