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

The FAG 2309 -K-TVH-C3 double-row self-aligning ball bearing (45x100x36 mm) compensates for misalignment and offers increased C3 radial clearance for demanding shaft mountings.

With the FAG 2309 -K-TVH-C3 self-aligning ball bearing, you get a double-row rolling bearing made from standard rolling-bearing steel (100Cr6) with a common hollow-spherical outer ring raceway. This design enables the two rows of balls to automatically compensate for angular misalignment and shaft deflection during operation. The open bearing has a 45 mm bore, an outer diameter of 100 mm and a width of 36 mm. A dimensionally stable polyamide cage guides the rolling elements with low vibration at operating temperatures ranging from -30 to +120 degrees.

What is the 2309 -K-TVH-C3 self-aligning ball bearing suitable for?

Design engineers and maintenance personnel prefer to use this bearing on long shafts or in split housing assemblies where misalignment or elastic deflection occurs. Thanks to the spherical outer ring raceway, the bearing adjusts angularly without generating excessive edge stresses. Typical applications include shaft mountings in general mechanical engineering. The open design allows for application-specific lubrication with oil or grease directly via the surrounding housing structure.

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

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or, using suitable mounting and withdrawal sleeves, on cylindrical shafts. In conjunction with the slightly increased radial bearing clearance C3, the required operating clearance is maintained even after press-fitting and the associated expansion of the inner ring. Furthermore, the increased bearing clearance helps to compensate for operational temperature differences between the rotating inner ring and the stationary outer ring.
