The MR117-2RS is an Ultra-Miniature Deep Groove Ball Bearing designed for applications where space is extremely limited and reliable sealing against contaminants is essential. Featuring double rubber contact seals (2RS) on both sides, this bearing provides superior protection against dust, moisture, and fine debris while maintaining smooth rotational performance. With a 7 mm bore and a compact 11×2.5 mm cross-section, it is ideal for micro motors, small instruments, precision mechanisms, and devices operating in challenging environmental conditions.
