MR 85 2RS ZEN 5x8x2,5 High Speed Ball Bearing

Miniature Ball Bearing for High Speed Applications

2RS Double Seal Protection and Smooth Operation

Technical Specifications and Industrial Use

Main Description:
The MR 85 2RS ZEN 5x8x2,5 is a miniature high speed ball bearing designed for compact mechanical systems requiring precision, low friction and stable rotational performance. With dimensions 5x8x2,5 mm (inner diameter x outer diameter x width), this bearing is widely used in micro motors, electric tools, robotics, instrumentation and other small-scale industrial applications.

The 2RS designation indicates double rubber seals on both sides, protecting the internal raceways and rolling elements from dust, moisture and contamination. This sealed design extends service life and reduces maintenance requirements compared to open ball bearings. The optimized internal geometry ensures smooth rotation and balanced radial load distribution.

Manufactured by ZEN, a brand established in Düsseldorf in 1992 and specialized in standard and precision bearings for industrial markets, the MR852RS offers high durability and consistent performance under high rotational speeds. Compared to larger cylindrical roller bearings, this ball bearing is ideal for applications where compact size and low torque resistance are critical.

The MR 85 2RS ZEN can operate as part of a small bearing unit (jednostka łożyskowa) or within a precision bearing housing (obudowa łożyskowa) in advanced mechanical assemblies. It is particularly suitable for light radial loads and high RPM environments where stable rotation and reliability are required.

For OEM manufacturers, service workshops and industrial distributors, this miniature ball bearing represents a reliable and space-efficient solution for precision engineering systems.
