623 series deep groove ball bearings

We are proud to introduce our new 623 series of deep groove ball bearings, engineered to deliver exceptional performance, longevity, and value across industrial applications. With cutting-edge design innovations and stringent manufacturing processes, the 623 series represents the future of bearing technology.

Featuring a deep groove geometry, these bearings are ideal for handling heavy radial loads and moderate bi-directional thrust loads. The inner and outer races are precision machined from vacuum melted and hardened chromium steel for maximum strength and durability. This material resists wear, deformation, and crack propagation even under extreme pressures or temperatures.

Inside the bearing, the hybrid multi-pocket machined brass cage is optimized to promote fluid lubricant circulation while minimizing operating noise and temperatures. The special cage profile also effectively retains the ultra-smooth chrome steel balls in precise relative positions for smooth and stable rotation.

All 623 series bearings utilize premium non-contact rubber seals on both sides. This enhanced sealing system prevents external contaminant ingress, maintaining near-zero internal contamination levels for dramatically extended service life. The rubber material also dampens vibration for quieter and more comfortable operation.

Advanced heat treatment techniques produce an optimal microstructure on the 623 series bearing races and balls. This allows superior dimensional control and geometric roundness, enabling balanced high speed operation up to DN values over 300,000. Quality control testing ensures every bearing meets strict ISO specifications.

The 623 series is available in popular metric sizes ranging from 5mm to 80mm bore diameters. Additional inch sizes and special dimensions can be custom produced. Single, double, and multi-row configurations suit different load applications. Pre-lubrication services are also offered.
