MF93 2rs Bearing Product Overview & Core Advantages
The MF93 2RS is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integrated rubber seals (2RS) on both sides, providing effective protection against contaminants while retaining lubrication. Engineered with chrome steel rings and balls along with a stainless steel cage, it delivers excellent durability and smooth operation. Its compact design (3mm bore × 9mm OD × 4mm width) makes it ideal for space-constrained applications while maintaining robust radial load capacity.
