MR62-ZZ Ultra-Miniature Ball Bearing | Precision Shielded | 2×6×2.5 mm | High-RPM Design

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.

The MR149-ZZ is a high-performance metric series miniature bearing engineered for applications that demand a balance of compact design and robust load-carrying capacity. With a 9mm bore diameter, this bearing is slightly larger than micro-series models, providing enhanced stability and radial support for small-scale rotating shafts. The dual metallic shields (ZZ) ensure that the internal raceways remain protected from dust and debris while maintaining the low-friction characteristics essential for high-speed efficiency.

The MR149 is a high-performance, metric-series miniature deep groove ball bearing specifically engineered for applications requiring a large bore-to-outside-diameter ratio in a slim-section profile. With a 9mm inner diameter and a narrow 3mm width, this bearing offers a unique solution for rotating components that need to pass over larger shafts without increasing the overall housing volume. Whether configured as open or shielded, the MR149 provides exceptionally low starting torque and high-speed stability, making it a cornerstone for modern mechatronics and precision hardware.

Designed for micro-mechanical systems where space is at an absolute premium, the MR105-ZZ is a top-tier miniature deep groove ball bearing. Equipped with dual steel shields (ZZ), it excels at keeping dust and debris out while securely retaining its factory-filled lubricant. Because these pressed metal shields operate entirely without contacting the inner ring, the MR105-ZZ guarantees virtually zero rotational drag. This ultra-low starting torque makes it the definitive solution for high-speed 5mm shaft applications, including RC car drivetrains, precision fishing reels, and delicate measurement instruments.
