FAQ

What is the significance of the 'E1' and 'K' suffixes in the 21313-E1-K designation?

The 'E1' suffix denotes an optimized internal design by FAG, providing a higher dynamic load rating and longer service life compared to older designs. The 'K' suffix indicates that the bearing has a tapered bore with a taper of 1:12, which allows it to be mounted on a cylindrical or tapered shaft using an adapter or withdrawal sleeve.

The appropriate lubrication depends heavily on the operating conditions, such as speed, load, and temperature. Generally, a high-quality lithium-based grease with an EP (Extreme Pressure) additive is suitable for a wide range of applications. For high-speed or high-temperature environments, oil lubrication might be necessary. Always consult the machine manufacturer's manual or a lubrication expert for specific recommendations.

Mounting a tapered bore bearing typically involves an adapter sleeve (e.g., H series) or a withdrawal sleeve (e.g., AH series). The bearing is driven up the sleeve until the required reduction in radial internal clearance is achieved. This ensures the correct interference fit. Using a hydraulic nut and feeler gauges to measure the clearance reduction is the most accurate method. Improper mounting can significantly reduce bearing life.
