01. Open Design for Low Friction & Easy Maintenance

Without seals or shields, the MR105 provides minimal rotational resistance, making it ideal for high-speed and low-torque applications. The open structure also allows for easy inspection, cleaning, and re-lubrication, extending service life in maintained systems.

02. Compact & Lightweight Construction

With ultra-small dimensions of 5×10×4 mm and a lightweight design, this bearing saves critical space and reduces moving mass in precision assemblies. Its small cross-section is ideal where dimensional constraints are severe.

03. High-Speed Capability with Smooth Operation

Manufactured to fine tolerances with polished raceways and precision-grade balls, the MR105 ensures quiet, smooth, and vibration-free rotation, essential for sensitive electrical and optical devices.
