627-2RS Sealed Deep Groove Ball Bearing for High-Speed Applications | 7×22×7 mm

The 6206-2RS is a robust, medium-series ball bearing specifically designed for mechanical systems operating in demanding or contaminated environments. Outfitted with dual contact rubber seals (2RS), this bearing provides an airtight barrier that prevents the ingress of water, fine dust, and abrasive grit. With its 30mm bore and 62mm outer diameter, the 6206-2RS is the preferred solution for agricultural equipment, outdoor industrial motors, and automotive drivetrain components where maximum protection is non-negotiable.

The 6206 is a high-precision open-type ball bearing engineered for advanced mechanical assemblies that utilize oil-bath or oil-mist lubrication systems. By removing integrated seals and shields, this unshielded configuration achieves the absolute minimum rotational resistance and zero contact friction. With its standard 30mm bore and 62mm outer diameter, the 6206 Open Type is a critical component for high-speed gearboxes, internal combustion engine components, and specialized industrial spindles where thermal efficiency is a priority.

The 6205-ZZ is a high-performance, mid-series ball bearing engineered to deliver an exceptional balance of radial load capacity and high-velocity efficiency. Featuring dual non-contact metal shields (ZZ), this bearing ensures consistent internal lubrication and provides a mechanical barrier against dust without increasing rotational torque. With a 25mm bore and 52mm outer diameter, the 6205-ZZ is the industry standard for small-to-medium electric motors, industrial blowers, and domestic appliance drive systems.

The 6205-2RS is a robust single-row ball bearing engineered to deliver balanced performance in demanding environments where radial space is moderate and protection is paramount. Equipped with dual contact rubber seals (2RS), this component effectively blocks entry of dust, moisture, and particulate matter while securely retaining internal grease. Featuring a 25mm bore, a 52mm outer diameter, and a 15mm width, it serves as a critical durable component for industrial pumps, agricultural machinery, household appliances, and automotive auxiliary systems.

The 6204-ZZ is a high-precision, mid-series ball bearing engineered to deliver a superior balance of radial load capacity and high-velocity stability. Equipped with dual non-contact metal shields (ZZ), this model excels at retaining internal grease and deflecting dry contaminants without increasing rotational torque. Featuring a 20mm bore and a 47mm outer diameter, the 6204-ZZ is the industry standard for high-performance electric motor rotors, power tool assemblies, and commercial office equipment requiring a maintenance-free rotational solution.

The 6203-2RS is a highly versatile, medium-duty rotational component engineered for mechanical systems exposed to moderate contamination. Equipped with twin synthetic rubber seals (2RS), this bearing establishes a tight, protective boundary that aggressively blocks out moisture, ambient dust, and operational debris. Featuring a standard 17mm bore alongside a 40mm outer diameter, the 6203-2RS is the optimal selection for fractional horsepower motors, automotive alternators, and household appliances where sustained, maintenance-free performance is required.

The 6203 Open is a versatile, light-series ball bearing designed for applications requiring maximum rotational speed and efficient heat dissipation. Unlike sealed variants, this open-type configuration features no contact seals or shields, allowing for minimal friction torque and the ability to utilize external lubrication systems tailored to specific operating conditions. With a compact 17mm bore, 40mm outer diameter, and 12mm width, it serves as a critical component in electric motors, household appliances, and automotive accessories where the housing provides sufficient environmental protection.

The 6202 Open is a versatile, high-performance ball bearing engineered for applications demanding minimal rotational resistance and extreme operational speeds. With a compact 15mm bore, 35mm outer diameter, and 11mm width, it is the preferred choice for electric motors, precision pumps, and light industrial equipment where external contamination control is managed by the housing assembly. As an open-type configuration, without integral seals or shields, this bearing relies on its clean, unobstructed internal geometry to deliver exceptionally low friction torque.
