6208 Open Deep Groove Ball Bearing | High-RPM Oil-Cooled Performance | 40×80×18 mm

Belonging to the globally standardized 62 series, the 6209 deep groove ball bearing offers an optimal balance between load-carrying capacity and high-speed capability. With boundary dimensions of 45 mm (bore), 85 mm (outer diameter), and 19 mm (width), this medium-duty bearing is highly adaptable to varied mechanical environments. The open architecture facilitates direct integration into oil-bath systems or central lubrication networks, giving engineers complete control over sealing and maintenance protocols for specific operating conditions.

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 6215 is a high-precision single-row radial bearing designed for larger industrial shafts requiring a combination of high-speed capability and significant radial load support. With a 75 mm bore, 130 mm outer diameter, and 25 mm width, this open-type bearing is a cornerstone component in heavy-duty machinery. Its open architecture allows for seamless integration into oil-bath or circulating lubrication systems, ensuring optimal heat dissipation and minimal friction torque during continuous operation.

The 6215-ZZ is a robust, medium-series deep groove ball bearing engineered to handle significant radial and axial loads in demanding industrial environments. Equipped with dual-sided metal shields (ZZ), this bearing provides an effective barrier against dust and metallic particles while retaining high-quality internal lubrication. With a 75 mm bore and a reinforced 25 mm width, the 6215-ZZ is the preferred choice for heavy-duty electric motors, agricultural machinery, and power transmission systems requiring long-term operational stability.

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 6215-2RS is a robust, premium-grade single-row deep groove ball bearing engineered to deliver unyielding reliability in demanding industrial environments. Unlike open or metal-shielded variants, this model is equipped with dual contact rubber seals (2RS) that create a formidable barrier against moisture, dirt, and heavy particulate contamination while permanently retaining the factory-applied lubricant. Manufactured to precise metric dimensions—featuring a 75 mm bore, 130 mm outer diameter, and 25 mm width—the 6215-2RS offers an optimal balance of high radial load capacity and steadfast durability for large-scale machinery, heavy electric motors, and agricultural equipment.

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.
