MR2010-ZZ Shielded Ball Bearing for Micro-Mobility | Low-Friction Design | 10x20x6 mm

The MR166-ZZ is a premium single-row miniature ball bearing designed for applications demanding frictionless rotation and reliable defense against dry particulate matter. Fitted with dual pressed steel shields (ZZ), this 6×16×5 mm unit excels at keeping internal factory lubrication locked in while deflecting airborne contaminants. Unlike rubber-sealed variants, the non-contact metal shields ensure absolute minimal torque resistance, making it an optimal solution for high-RPM mechanisms such as 3D printer extruders, micro-stepping motors, and precision office electronics where operational speed and heat dissipation are primary concerns.

The MR115-ZZ is a high-performance miniature deep groove ball bearing specifically constructed for applications where unhindered rotational speed and strict space limitations are top priorities. Featuring dual pressed steel shields (ZZ), this 5×11×4 mm component effectively guards the internal raceways against dry particulates and dust while retaining the factory-applied lubricant. Because the metal shields do not make physical contact with the inner ring, this bearing delivers zero-drag operation, making it an exceptional choice for rapid-motion assemblies like RC vehicles, fishing reels, and delicate micro-motors.

The MR115-2RS is a robust single-row miniature ball bearing engineered specifically for high-performance applications where exposure to external contaminants is a constant challenge. Outfitted with dual synthetic rubber contact seals (2RS), this 5×11×4 mm component provides a formidable barrier against moisture, fine grit, and liquid splashes. Unlike shielded versions, the reinforced rubber seals maintain a light-contact interface with the inner ring, ensuring that the internal factory-grade lubricant remains securely sealed within the raceways, significantly extending the service life of the bearing in outdoor or non-sterile environments.

The MR106-ZZ is a precision-engineered single-row miniature ball bearing designed for high-velocity applications where low rotational torque is a priority. Featuring dual-side metal shields (ZZ), this ultra-slim 6×10×3 mm component offers an effective defense against dust and dry contaminants without the friction drag associated with rubber contact seals. The non-contact metal shields ensure that the factory-applied grease remains contained within the raceways, allowing for exceptionally smooth, high-RPM performance in clean or semi-protected mechanical environments.

The MR106-2RS is a highly resilient, single-row miniature deep groove ball bearing designed for precision applications where space is limited and environmental protection is paramount. Measuring just 6×10×3 mm, this micro-bearing is equipped with premium dual synthetic rubber contact seals (2RS). This sealing mechanism forms an aggressive barrier against fine dust, particulate matter, and liquid ingress. Unlike standard metal shields, the NBR rubber seals maintain a continuous, light-friction contact with the bearing's inner ring, locking the factory-applied lubricant inside and drastically reducing the need for maintenance in challenging or outdoor environments.

The MR106 Open is a high-precision, unsealed miniature ball bearing engineered for internal applications that demand the absolute minimum in rotational resistance. Characterized by its "Open" configuration, this 6×10×3 mm component lacks metal shields or rubber seals, completely eliminating any potential contact drag. By exposing the internal raceways and rolling elements, it allows for unrestricted, ultra-smooth motion. This design is the optimal choice for enclosed mechanical systems operating in clean environments, or within dedicated oil baths where continuous external lubrication is applied.

The MR95-ZZ is an ultra-compact, single-row deep groove ball bearing engineered for applications that demand high-speed rotation and minimal friction within tightly constrained spaces. With microscopic dimensions of just 5×9×3 mm, this bearing is equipped with dual pressed steel shields (ZZ). Unlike rubber seals, these non-contact metal shields provide excellent protection against larger particulates and dust without generating drag. This frictionless shielding ensures the bearing can operate at exceptionally high RPMs while retaining its internal lubrication, making it an indispensable component for sensitive, high-velocity micro-mechanisms.

The MR95-2RS is a highly resilient, single-row micro ball bearing tailored for applications where space is extremely limited but environmental protection is non-negotiable. Equipped with twin synthetic rubber contact seals (2RS) on both sides, this compact 5×9×3 mm unit creates an impenetrable shield against water droplets, fine dust, and operational debris. The friction-optimized rubber lips make direct contact with the inner ring, effectively locking the factory-supplied lubricant inside while blocking external corrosive elements, thereby maximizing the lifecycle of the assembly in challenging outdoor or harsh industrial settings.
