FAQ

What is the significance of the 'EKTN9/C3' suffix?

The suffix provides key details: 'EK' signifies a tapered bore (taper 1:12) with an annular groove and lubrication holes in the outer ring. 'TN9' indicates a glass fibre reinforced polyamide 6,6 cage, which is lightweight and allows for high speeds. 'C3' refers to an internal radial clearance that is greater than normal, suitable for applications with tight fits or temperature variations.

A bearing with a tapered bore is mounted either on a tapered shaft journal or on a cylindrical shaft using an adapter sleeve or withdrawal sleeve. The mounting process involves driving the bearing up the tapered seat, which reduces its internal clearance. It is critical to use feeler gauges to measure the clearance reduction to achieve the correct operational fit and prevent premature failure.

The polyamide cage (TN9) offers excellent performance but has temperature limitations. It is generally stable for continuous operation up to 120 deg C (250 deg F). For applications with consistently higher operating temperatures, a bearing with a steel cage (suffix 'M' or no cage suffix) would be a more suitable choice.
