Self-Aligning Ball B. FAG 1210 -K-TVH-C3

The FAG 1210 -K-TVH-C3 double-row self-aligning ball bearing (50x90x20 mm) compensates for misalignment and is suitable for shaft mounting with shrink sleeves.

The FAG 1210 -K-TVH-C3 from FAG is an open roller bearing made from standard bearing steel (100Cr6) with the main dimensions of 50 mm bore, 90 mm outer diameter and 20 mm width. Thanks to the shared hollow-spherical raceway in the outer ring, the design compensates for both static and dynamic angular misalignment and shaft deflection during operation. It is manufactured to the Normal tolerance class (P0/PN or ABEC 1). This provides maintenance engineers and technical purchasers with a precisely fitting bearing for bearing locations affected by misalignment.

What is the 1210 -K-TVH-C3 self-aligning ball bearing suitable for?

This double-row self-aligning ball bearing is primarily designed for mounting long shafts or those prone to deflection, where misalignment may occur between the bearing housings. Typical applications include mechanical assemblies and shaft mountings where housing inaccuracies or elastic shaft deformations need to be compensated for. Thanks to the polyamide cage (TVH), the bearing operates with low friction at operating temperatures ranging from –30 to +120 degrees Celsius. The open design also allows for flexible lubrication with oil or grease directly within the housing.

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

The tapered bore with a 1:12 taper simplifies mounting on cylindrical shafts using a clamping or withdrawal sleeve, which facilitates installation and removal during maintenance. As sliding the inner ring onto the sleeve reduces the bearing clearance, the 1210 -K-TVH-C3 self-aligning ball bearing is supplied ex-works with a slightly increased radial clearance (C3). This increased initial clearance compensates for expansion during assembly and thermal expansion during operation, thereby ensuring smooth running without harmful preload.
