Self-Aligning Ball B. FAG 2309 -K-2RS-TVH-C3

The FAG 2309 -K-2RS-TVH-C3 self-aligning ball bearing, measuring 45 × 100 × 36 mm with a tapered bore and 2RS seals on both sides, automatically compensates for misalignment in shaft-bearing assemblies.

Manufactured from standard roller bearing steel 100Cr6, the double-row design accommodates shaft deflection and axial displacement during operation without generating harmful forced forces. The shared hollow spherical raceway in the outer ring guides both rows of balls with low friction and accommodates angular misalignment. Thanks to the seal that runs on both sides, the lubricant remains within the bearing chamber, whilst dirt particles and moisture are effectively kept out. The integrated polyamide cage ensures smooth running within a temperature range of -30 to +100 degrees.

In which applications does the 2309 -K-2RS-TVH-C3 self-aligning ball bearing compensate for misalignment?

Designs featuring long shafts or flexible support structures are prone to deflection or misalignment between the bearing seats under operational loads. The 2309 -K-2RS-TVH-C3 self-aligning ball bearing primarily accommodates radial loads and tolerates misalignment without increased edge pressure. It is primarily used in applications where ambient dust or splashing water is present and a sealed rolling bearing, protected against contamination, is required.

What are the advantages of a tapered bore and C3 clearance?

The suffix ‘K’ denotes the tapered bore with a taper ratio of 1:12. This design facilitates mounting on cylindrical shafts using a clamping or withdrawal sleeve and allows for precise adjustment of the bearing clearance. When the bearing is slid onto the tapered seat to the specified extent, the radial clearance is measurably reduced. The increased bearing clearance class C3 helps to ensure that the required operating clearance is maintained after assembly and during operation-induced heating.
