6211-2RS Rubber Sealed Deep Groove Ball Bearing for Harsh Environments | 55x100x21 mm

The 6212-2RS is a premium single-row deep groove ball bearing equipped with double contact rubber seals. Designed to lock in optimal lubrication and keep out harmful contaminants, this bearing ensures maintenance-free operation in challenging, debris-heavy environments. Featuring a 60 mm bore, a 110 mm outer diameter, and a 22 mm width, it provides an exceptional balance of radial load capacity and speed, making it highly effective for electric motors, agricultural equipment, and general industrial machinery where reliability is non-negotiable.

The 6212 Open is a highly efficient, versatile ball bearing engineered for systems that demand rapid rotational speeds and low friction. Featuring an unsealed and unshielded design, it allows for unrestricted circulation of external lubricants, making it the perfect choice for enclosed systems with oil bath or circulating oil lubrication. With its precisely calibrated 60 mm bore, 110 mm outer diameter, and 22 mm width, this bearing delivers reliable medium-duty performance across a wide array of industrial and automotive powertrains.

The 6211-ZZ is a high-precision, single-row deep groove ball bearing equipped with dual non-contact metal shields. This design is engineered for applications requiring high-speed rotation and basic protection against larger particles and dust without the friction associated with rubber seals. Featuring a 55 mm bore, a 100 mm outer diameter, and a 21 mm width, the 6211-ZZ offers a reliable, low-maintenance solution for electric motors and power transmission systems where heat dissipation and high RPMs are essential.

The 6211-2RS is a robust, single-row deep groove ball bearing specifically engineered for maximum protection against environmental contaminants. Outfitted with dual contact rubber seals (NBR), this bearing is designed to thrive in applications where dust, moisture, and debris are prevalent. Measuring 55 mm (bore) x 100 mm (OD) x 21 mm (width), it provides an ideal combination of sealing efficiency and radial load capacity, ensuring a long service life for industrial and outdoor equipment.

The 6211 Open is a high-performance, single-row radial ball bearing engineered for systems that require maximum rotational speed and minimal internal friction. Without the restriction of seals or shields, this bearing allows for the free flow of external lubricants, making it the ideal choice for enclosed gearboxes and oil-circulating systems. With a 55 mm bore and a precision-ground 100 mm outer diameter, the 6211 provides a stable, low-torque solution for industrial machinery where heat dissipation is a primary concern.

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.
