FAQ

What does the ‘K’ in 1312 EKTN9/C3 signify?

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

Why is C3 clearance important for this bearing?

C3 denotes a radial internal clearance that is greater than normal. This is crucial in applications where there are temperature differences between the inner and outer rings, or where a tight fit is required, preventing the bearing from seizing during operation.

What is the correct mounting procedure for a bearing with a tapered bore?

A bearing with a tapered bore should be driven up the tapered seat of the shaft or adapter sleeve. The correct fit is achieved by measuring the reduction in radial internal clearance. This ensures the bearing is mounted securely without being too tight, which could lead to premature failure.
