The design adopted by NSK's various angular contact ball bearings can meet these diverse requirements. Angular contact ball bearings have contact angles, so they can withstand both radial loads and large axial loads in a single direction. In addition, when angular contact ball bearings are loaded with radial loads, due to the axial component of the load, they are usually used in combination with several bearings, such as 2, 3, or 4. NSK has and provides full specifications of angular contact ball bearings.
characteristic
High quality steel - using ultra clean steel that can extend bearing life by 80%
Advanced lubrication technology - NSK's lubricant technology can extend the lifespan of lubricating grease and improve bearing performance
High grade steel balls - quiet and smooth when rotating at high speeds
The ultra precision machined raceway surface - a special honing process that controls noise to a small extent, improves lubricant dispersion, and extends its lifespan.
Contact angle - various products with contact angles of 15 degrees, 25 degrees, 30 degrees, and 40 degrees are available
Cage - Various cages made of polyamide, steel, and brass are available
Single row angular contact ball bearing
This type of bearing has a contact angle, so it is suitable for bearing axial loads in one direction or composite loads.
Structurally, axial separation occurs when subjected to radial loads, so two bearings can be used in opposition or in pairs with two or more bearings. Single row angular contact ball bearings can use preloading to improve rigidity, making them suitable for machine tool spindles with high rotational accuracy.
Double row angular contact ball bearing
The single row angular contact ball bearing is double connected back to back, with the inner and outer rings forming a single structure. Capable of withstanding axial loads in two directions, with torque load capacity. Can be used as a fixed end bearing. Use stamped cages.
Point contact ball bearing
The inner ring is divided into two parts, and one bearing can withstand axial loads in both directions. The contact angle is 35 °, and the axial load capacity is large, suitable for bearing pure axial loads or composite loads with large axial loads. Use copper alloy car made cages.
