FAQ

The 'K' suffix indicates that the bearing has a tapered bore, typically with a 1:12 taper. This design allows for easy mounting and dismounting using an adapter sleeve or withdrawal sleeve on a cylindrical shaft.

C3 is an internal radial clearance that is greater than the 'Normal' clearance. It is used in applications where there may be a tight fit on the shaft or in the housing, or where a temperature differential between the inner and outer rings could reduce operational clearance.

The S11 suffix means the bearing rings are heat-stabilized for operation at temperatures up to 200 deg Celsius. It is critical to use a compatible high-temperature grease to ensure proper lubrication and achieve the expected service life in such conditions.
