NSK Ball Bearings

Movement and control

Deep groove ball bearings

NSK is the world leader in deep groove ball bearings.

These bearings are the most common type of rolling element bearing, and their field of application is very wide, especially where high speeds are present and energy losses must be minimal. NSK bearings can take not only radial loads but also axial loads in any direction. This type of bearing is easy to install and is suitable for a variety of equipment designs and operating conditions.

Angular contact ball bearings

We bring to your attention the most complete range of angular contact ball bearings, which has been specially developed in connection with the growing requirements of equipment manufacturers. These bearings have a contact angle, therefore, they can withstand significant axial loads in one direction simultaneously with radial loads. Moreover, since the axial component is generated when a radial load is applied, these bearings are usually used as duplex, triplex, quadruplex or multiplex arrangements.

Self-aligning ball bearings

Self-aligning bearings are recommended for applications where shaft / housing alignment is difficult and the shaft may bend. The outer ring has a spherical raceway, and its center of curvature coincides with that of the bearing. Thus, the axis of the inner ring, balls and cage can deviate somewhat around the center of the bearing. Due to the fact that the contact angle is small, the axial load capacity is low. Allowable dynamic misalignment is approximately 0.07 to 0.12 radians (4-7 degrees ).

Thrust ball bearings

Designed to withstand axial loads at high speeds, NSK thrust ball bearings consist of a "washer type" bearing ring with a groove-like raceway to accommodate the balls. Thrust ball bearings are classified into flat or spherical end bearings depending on the shape of the outer ring. These ball bearings can only handle axial loads.

NSK thrust ball bearings are available in two designs: single ball bearing and double ball bearing. A single thrust ball bearing consists of two rings and one set of balls with a cage. The double thrust ball bearing consists of three rings and two sets of balls with a cage. Ball sets with cage are separated by a loose ring.
