6215-ZZ Industrial Deep Groove Ball Bearing | High-Load Capacity | 75×130×25 mm

The 6208-ZZ is a precision-engineered, single-row deep groove ball bearing featuring dual-sided metal shields. Designed for applications that require a balance between high-speed rotation and basic protection against debris, this bearing minimizes friction while retaining critical lubrication. With a 40 mm bore, 80 mm outer diameter, and an 18 mm width, the 6208-ZZ is a staple component in electric motors, centrifugal pumps, and automotive systems where maintenance-free performance and heat resistance are paramount.

The 6208-2RS is a high-performance, double-sealed single-row deep groove ball bearing designed for durability in environments where dust, dirt, and moisture are present. Unlike open bearings, this model features dual Nitrile Butadiene Rubber (NBR) seals that retain high-quality grease and prevent the ingress of contaminants. With a 40mm bore and 80mm outer diameter, the 6208-2RS offers a perfect balance of load capacity and compact design, making it a staple for electric motors and industrial machinery.

The 6208 Open is a high-precision, unshielded single-row ball bearing engineered for systems where external lubrication—such as an oil bath, splash lubrication, or circulating oil mist—is readily available. By removing the physical barriers of seals or shields, this bearing achieves the lowest possible rotational resistance, making it the primary choice for high-speed gearboxes and industrial transmissions that demand peak energy efficiency.

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.
