SKF 2211 EKTN9/C3

SKF 2211 EKTN9/C3 Self-Aligning Ball Bearing

Description

The SKF 2211 EKTN9/C3 is a high-quality self-aligning ball bearing designed to accommodate misalignment between the shaft and housing. Its two rows of balls and a common sphered raceway in the outer ring allow the bearing to operate even with angular misalignment. This particular model features a tapered bore for mounting with an adapter sleeve, an optimized internal design for higher load ratings, a robust polyamide cage, and C3 internal clearance for applications with higher speeds or temperature differentials.

FAQ

What does the ‘EKTN9/C3’ suffix mean?

The suffix breaks down as follows: ‘E’ indicates an optimized internal design for higher performance. ‘K’ signifies a tapered bore (taper 1:12). ‘TN9’ refers to the snap-type, glass fibre reinforced polyamide 6,6 cage. ‘C3’ denotes an internal radial clearance that is greater than normal, suitable for higher speed operation or applications with a tight fit.

What is the correct way to mount a bearing with a tapered bore?

A bearing with a tapered bore is typically mounted on a tapered shaft journal or on a cylindrical shaft using an adapter sleeve or a withdrawal sleeve. The mounting process involves driving the bearing up the tapered seat to achieve the required reduction in radial internal clearance. It is crucial to use proper tools and measure the clearance reduction accurately to avoid preloading the bearing.

Is the polyamide cage (TN9) suitable for high-temperature applications?

The TN9 polyamide cage has a maximum continuous operating temperature of around 120 deg C (250 deg F). For applications expecting higher temperatures, a bearing with a steel cage (e.g., suffix M) would be more appropriate. Always consult the SKF datasheet for specific temperature limits and chemical compatibility.
