SKF 2309 EKTN9 Self-aligning Ball Bearing

Description

The SKF 2309 EKTN9 is a high-performance self-aligning ball bearing designed for reliability in demanding industrial applications. Its key feature is the ability to accommodate static and dynamic misalignment, thanks to its two rows of balls and a common sphered raceway in the outer ring. This bearing is supplied with a tapered bore for mounting with an adapter sleeve on cylindrical shafts.

FAQ

The 'K' suffix indicates that the bearing has a tapered bore with a standard taper of 1:12. This allows for mounting on a tapered shaft or using an adapter sleeve. The 'TN9' suffix specifies that the bearing is fitted with a snap-type cage made of glass fibre reinforced polyamide 6,6, which offers good performance at high speeds and moderate temperatures.

Mounting a tapered bore bearing involves driving it up the tapered seat. The correct fit is achieved by controlling either the axial drive-up distance or the reduction in radial internal clearance. Using an adapter sleeve (H series) or a withdrawal sleeve (AH series) is a common method for mounting on cylindrical shafts. Always use proper mounting tools and refer to SKF's guidelines to avoid damaging the bearing.

The SKF 2309 EKTN9 is a self-aligning ball bearing designed to accommodate both static and dynamic angular misalignment between the shaft and housing. Due to its internal geometry with a sphered outer ring raceway, it can typically handle misalignments of several degrees without affecting its performance or lifespan, making it ideal for applications with shaft deflection or initial mounting inaccuracies.
