PTN 6205 2RS Deep Groove Ball Bearing

Description

The PTN 6205 2RS is a versatile and widely used single-row deep groove ball bearing. It features contact seals on both sides, made of nitrile butadiene rubber (NBR), which provide excellent protection against dust, dirt, and moisture, while also retaining the factory-filled grease. This design makes the bearing maintenance-free for its entire service life. It is engineered to accommodate both radial and axial loads in both directions and is suitable for a broad range of speeds.

FAQ

The '2RS' designation indicates that the bearing is sealed on both sides ('2R') with a contact seal ('S'). These seals are typically made of steel-reinforced NBR (Nitrile Butadiene Rubber) and make physical contact with the inner ring to provide a very effective barrier against contaminants and moisture.

While the 2RS seals offer excellent protection, the friction from the contact seals generates heat, which can limit the maximum permissible speed compared to an open or shielded (ZZ) bearing. It is ideal for moderate speed applications. Always consult the manufacturer's datasheet for specific speed ratings.

The PTN 6205 2RS comes pre-lubricated with a specific amount of high-quality grease, designed to last the lifetime of the bearing. It is considered 'lubricated-for-life' and does not require any re-lubrication or maintenance.
