High-Speed 2×5×2.5 mm MR52 ZZ RS Micro Ball Bearing

Product Overview

For engineers and buyers specializing in micro-mechanics, precision instruments, and compact electronics, the MR52 miniature ball bearing is an essential component that balances ultra-compact dimensions with reliable performance. As a standard part of the widely recognized “MR” series, this bearing provides a proven solution for applications demanding smooth rotational motion within the strictest space constraints.

Key Features:

• Ultra-Compact & Space-Saving
  The primary advantage of the MR52 miniature ball bearing is its extremely small footprint, allowing for innovative and dense product designs where larger bearings simply cannot fit.

• High Precision & Smooth Operation
  Manufactured to tight tolerances and high precision grades, it ensures exceptionally smooth, quiet, and low-vibration rotation. This is vital for the accuracy and performance of optical devices, measuring instruments, and sensitive electronic equipment.

• Versatility in Demanding Environments
  The availability of different materials (standard steel, stainless, hybrid ceramic) allows designers to select the optimal MR52 bearing for harsh conditions involving moisture, chemicals, or high temperatures.
• Reliable Performance & Long Life
  When correctly specified and lubricated, this precision miniature component delivers a long and reliable service life, reducing failure rates and maintenance needs in hard-to-access assemblies.
• Industry Standard & Interchangeable
  As a standard component in the MR series, it is widely available and interchangeable with products from other major manufacturers, simplifying sourcing, prototyping, and production.
