MF52-ZZ Flanged Micro Ball Bearing for High-Precision Devices & Robotics | 2×5×2.5 mm

The MF148-ZZ is a high-performance, metric-dimensioned miniature bearing characterized by its integrated outer ring flange. This structural feature is engineered to simplify housing designs by allowing the bearing to be securely axial-located without the need for complex internal shoulders. Equipped with dual metal shields (ZZ), this model provides a robust defense against dust and debris while retaining high-quality lubrication, making it an essential component for precision-heavy environments where space is at a premium.

The MF106-ZZ is a highly specialized metric miniature deep groove ball bearing equipped with an integrated outer ring flange. Measuring 6mm in bore diameter with a slim 10mm outer diameter, this flanged architecture is engineered to simplify mounting processes and eliminate the need for complex housing shoulders. Featuring dual pressed steel shields (ZZ), the bearing creates a fully enclosed micro-environment that securely retains factory-filled grease while effectively blocking external dust, debris, and particulate matter. This makes the MF106-ZZ an ideal component for compact assemblies requiring reliable, maintenance-free rotation and precise axial positioning.

The MF85-ZZ is a high-precision, metric-series miniature ball bearing engineered with an integrated flange on the outer ring. This specific architecture is designed to simplify mechanical assemblies by providing a built-in locating surface, allowing the bearing to be securely positioned in thin-walled housings without internal shoulders. Featuring dual metal shields (ZZ), the MF85-ZZ balances high-speed performance with effective protection against environmental contaminants, making it a cornerstone component for space-sensitive precision engineering.

The MF63-ZZ is an ultra-compact, metric flanged deep groove ball bearing engineered for applications where space constraints are severe and precise axial positioning is mandatory. With a micro 3mm bore and a 6mm outer diameter, this bearing incorporates a solid outer ring flange that acts as a built-in stopper. This architectural advantage eliminates the need to machine intricate housing shoulders, simplifying the integration process. Outfitted with dual non-contact pressed steel shields (ZZ), the MF63-ZZ creates a secure internal cavity that locks in premium factory lubrication while aggressively repelling microscopic dust and particulate contaminants.

Engineered for highly compact assemblies requiring exact axial positioning, the MF84-ZZ is a premium miniature deep groove ball bearing featuring an integrated outer-ring flange. Outfitted with dual non-contact metallic shields (ZZ), it delivers exceptional defense against dust and debris while maintaining the factory-applied lubrication. Because the metal shields avoid physical friction with the inner ring, the MF84-ZZ ensures minimal startup torque and ultra-smooth rotation. This makes it an essential component for high-RPM, space-constrained 4mm bore applications, including precision RC vehicles, micro-stepper motors, and delicate optical instruments.

Developed for ultra-low profile mechanisms demanding flawless axial location, the MF52-ZZ stands as an elite-tier micro ball bearing engineered with an integrated outer-ring flange. Featuring dual non-contact steel shields (ZZ), it blocks environmental particulates effectively while keeping its pre-filled specialized grease intact. Since these metallic shields do not rub against the inner ring, frictional resistance and startup torque remain exceptionally low, paving the way for ultra-smooth rotation. This makes it an indispensable component for sub-miniature 2mm bore applications, including high-precision RC servos, medical equipment, and micro-stepper motors.
