Self-Aligning Ball B. FAG 2307 -K-TVH-C3

FAG double-row self-aligning ball bearing 2307 -K-TVH-C3 with tapered bore (35x80x31 mm), slightly increased C3 clearance and a polyamide cage to compensate for misalignment.

The FAG 2307 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a common hollow-spherical raceway in the outer ring. This design automatically compensates for angular misalignment and shaft deflection during operation. With key dimensions of 35 mm bore diameter, 80 mm outer diameter and 31 mm width, this open bearing offers a high radial load-carrying capacity. The integrated polyamide cage ensures quiet, low-friction operation in demanding industrial drives.

What is the 2307 -K-TVH-C3 self-aligning ball bearing suitable for in operation?

This self-aligning ball bearing is primarily used where flexible shafts or misalignment between bearing housings occur. Typical applications include bearing arrangements with long shafts or separate housings in general mechanical engineering. As the outer ring allows the ball rows to be freely adjusted, the bearing prevents disruptive edge pressures during deflection. In protected or separately sealed housings, the design benefits from the open construction, which allows for a flexible supply of lubricant via oil or grease.

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

The tapered bore with a 1:12 taper simplifies assembly on tapered shaft seats or, using standardised adapter sleeves, on cylindrical shafts. The slightly increased radial bearing clearance (C3) compensates for the inevitable reduction in radial clearance when the inner ring is pushed on axially. At the same time, it accommodates thermal expansion within the permissible temperature range of -30 to +120 degrees. The polyamide cage (TVH) offers excellent elasticity and low weight. When selecting bearings, take into account tolerance class P0/PN to ensure precise concentricity.
