61700, 61800 and 61900 Series Deep Groove Ball Bearings are specialized thin-section bearing solutions designed for applications requiring limited installation space, high rotational speed and reliable operating performance.

Compared with standard deep groove ball bearing series, these bearings feature a smaller cross-section and lighter design while maintaining stable radial load capacity. They are widely used in high-speed motors, precision instruments, automation equipment, medical devices and compact mechanical systems.

For international distributors, OEM manufacturers and equipment builders, choosing thin-section deep groove ball bearings requires more than matching dimensions. Bearing speed capability, friction level, noise performance, sealing design, material quality and supply consistency are critical factors affecting equipment reliability.

We supply 61700, 61800 and 61900 Series Deep Groove Ball Bearings with open, ZZ shielded and 2RS sealed options, supporting standard replacement requirements and customized OEM applications.
