FAQ

Question?

What does the '2RSR' suffix on the FAG 6306-2RSR bearing signify?

The '2RSR' designation is specific to FAG and indicates the type of seal. '2' means the bearing is sealed on both sides. 'RSR' refers to a contact seal made from nitrile butadiene rubber (NBR), which is reinforced with a sheet steel washer. This type of seal provides excellent protection against dust, dirt, and moisture while effectively retaining the lubricant inside the bearing.

Can I use a different type of grease with this 6306-2RSR bearing or do I need to clean out the factory grease?

The FAG 6306-2RSR comes pre-lubricated with a high-quality, factory-filled grease designed for a wide range of operating conditions and long life. It is generally not recommended to mix greases, as incompatibilities can lead to premature bearing failure. For most standard applications, the factory fill is sufficient for the bearing's entire service life.

Is the FAG 6306-2RSR suitable for high-speed applications?

The suitability for high-speed applications depends on the limiting speed of the bearing. For the 6306-2RSR with contact seals, the speed is limited by the friction generated at the seal lip. The reference speed for this bearing is typically around 6,000 RPM. For applications requiring very high rotational speeds, a bearing with non-contact seals (like a 6306-2Z) or an open bearing would be a more appropriate choice.
