The MR105 is a Miniature Deep Groove Ball Bearing designed for high-precision applications in compact assemblies where minimal friction and smooth operation are essential. With an open design (no seals or shields), this bearing offers unobstructed performance, making it ideal for clean environments, high-speed mechanisms, and applications requiring frequent re-lubrication. Featuring a 5 mm bore and compact 10×4 mm dimensions, it delivers reliable radial and axial load support in tight spaces.
