Product Classification and Characteristics of NSK Angular Contact Ball Bearings

Source: FAG bearings  Tags: News

NSK angular contact ball bearings have a contact angle, so they can withstand radial offset and large radial displacement in one direction at the same time. All use a combination of several bearings, such as 2, 3 or 4 etc. NSK has and provides full specifications of angular contact ball bearings.

NSK angular contact ball bearing product classification

Single row angular contact ball bearings
This bearing has a contact angle, so it can withstand a load in one direction, or a combined load. Structurally, they alternately separate after being subjected to radial loads, so two bearing pairs are placed for use, or two or more pairs are used in pairs. Single-row angular contact ball bearings can be preloaded to increase rigidity. Therefore, they are suitable for high-rotation precision machine tool spindles. Angular contact ball bearing cage. However, depending on the conditions, synthetic resin cages or polyamide molding cages are also used.

Structural characteristics of paired double bearings

Back-to-back matched 
Can bear radial load and axial load in two directions. The action point distance is large, so it is suitable for applications with large moment load.

Frontal matched 
Can bear radial load and axial load in two directions.
Compared with back-to-back double connection, the point of action distance is small, so the torque load capacity is poor.

Tandem configuration
Can bear radial load and axial load in one direction. Two bearings are used to bear the axial load, so it is used in the occasions where the load is large in one direction.

Double row angular contact ball bearings
Double-row single-row angular contact ball bearings are back-to-back, and the inner and outer rings are integrated into one. Can withstand axial load in two directions, with torque load capacity. Can be used as a fixed-end bearing. Use stamped cages. Need bearing NSK 3213A online , click here 

Point contact ball bearing
The inner ring is divided into two, and one bearing can bear the axial load in two directions. The contact angle is 35 °, and the axial load capacity is large, which is suitable for bearing pure axial load, or a composite load with large axial load. Use copper alloy car cage.
