FAQ

The '2RS1' suffix indicates that the bearing is equipped with contact seals on both sides. These seals are typically made of sheet steel reinforced NBR (nitrile butadiene rubber) and provide excellent protection against the ingress of dust, dirt, and moisture, while also retaining the lubricant within the bearing.

Yes, NSK bearings with the 2RS1 suffix are supplied greased for life. They are pre-filled with a high-quality lubricant suitable for a wide range of operating conditions and do not require any additional lubrication before or during their service life.

The 'TNG' marking specifies the material and design of the bearing cage. In this case, it refers to a snap-type cage made from glass-fibre reinforced polyamide 66. This material offers a favorable combination of strength and elasticity, low friction, and is suitable for high-speed operation.
