6206-2RS Sealed Deep Groove Ball Bearing | Weatherproof Metric Bearing | 30×62×16 mm

The 6209-2RS is a high-performance radial bearing equipped with contact rubber seals on both sides to provide superior protection against liquid ingress and fine particulates. Measuring 45 mm (bore), 85 mm (outer diameter), and 19 mm (width), this model is part of the versatile 62 series. Unlike open or shielded variants, the 2RS configuration utilizes nitrile butadiene rubber (NBR) seals that maintain constant contact with the inner ring, ensuring the internal lubricant remains uncontaminated even in washdown or high-humidity environments.

The 6209-ZZ is a precision-engineered radial bearing featuring two non-contact metal shields to protect the internal rolling elements from larger debris while maintaining high-speed efficiency. With dimensions of 45 mm (bore), 85 mm (outer diameter), and 19 mm (width), this 62-series bearing is designed for applications where low friction torque is essential. Unlike rubber-sealed variants, the metallic shields (ZZ or 2Z) do not contact the inner ring, allowing the bearing to operate at significantly higher velocities with minimal heat generation.

The S6203-2RS is a premium, single-row deep groove ball bearing engineered specifically for harsh, corrosive environments. Manufactured from high-grade stainless steel rather than standard chrome steel, this bearing provides exceptional resistance to rust, moisture, and chemical exposure. Featuring dual Nitrile Butadiene Rubber (NBR) seals, it securely locks in high-quality grease while keeping out water and particulate matter. With standardized dimensions of a 17mm bore, 40mm outer diameter, and 12mm width, the S6203-2RS delivers a reliable, long-lasting solution for washdown and outdoor applications.

The 6207-2RS is a premium-grade, single-row deep groove ball bearing engineered to deliver robust performance and exceptional load support in demanding industrial environments. Unlike low-friction metal-shielded variants, this model is equipped with dual nitrile rubber contact seals (2RS) that create a tight, physical barrier against moisture, dirt, and heavy abrasives while securely locking in the factory grease. Featuring standard metric dimensions—a 35 mm bore, 72 mm outer diameter, and 17 mm width—the 6207-2RS serves as an essential mechanical component for electric motors, agricultural equipment, and heavy-duty transmission systems.

The 629-ZZ is a premium-grade miniature radial ball bearing engineered for applications that demand high rotational speeds, minimal friction, and reliable debris protection. Encased with dual pressed-steel shields (ZZ), this bearing effectively retains internal lubrication while preventing the entry of larger particulates. Featuring a versatile 9mm inner bore, a 26mm outer diameter, and an 8mm width, the 629-ZZ is the component of choice for handheld power tools, high-performance hobby mechanics, and automated manufacturing systems requiring exceptionally smooth continuous rotation.

The 626 Open is a high-precision miniature radial ball bearing designed for internal machinery applications where external contamination is not a factor. Manufactured without shields or rubber seals, this unshielded bearing provides completely unrestricted access to the balls and raceways. This open architecture makes it the ultimate choice for enclosed systems that utilize continuous oil bath or oil mist lubrication. With a 6mm bore, a 19mm outer diameter, and a 6mm width, it delivers absolute minimum rolling resistance and exceptional heat dissipation.

The 623-ZZ is an ultra-compact, high-precision miniature ball bearing engineered for micro-mechanical systems where space is strictly limited but high-speed performance is essential. Outfitted with twin pressed steel shields (ZZ) to safely retain high-grade lubricant and deflect micro-debris, this bearing delivers exceptionally low rotational resistance. With a tiny 3mm bore, a 10mm outer diameter, and a 4mm width, the 623-ZZ is the definitive solution for 3D printer extruders, micro-scale drone motors, and delicate instrumentation requiring frictionless, ultra-smooth movement.

The 6206-ZZ is a highly versatile, single-row deep groove ball bearing from the standard 6200 light series, featuring dual pressed steel shields. Designed with a 30 mm bore, a 62 mm outer diameter, and a 16 mm width, this model is celebrated as one of the most reliable "workhorse" bearings in the industrial sector. The non-contact metal shields are engineered to retain the factory-filled grease while effectively deflecting larger particulate matter and debris. Because these shields do not physically rub against the inner ring, the 6206-ZZ operates with remarkably low friction, making it the optimal choice for high-speed electric motors, pumps, and automated machinery where both moderate protection and maximum rotational efficiency are required.
