Self-Aligning Ball B. FAG 1205 -K-TVH-C3

The double-row self-aligning ball bearing 1205-k-tvh-c3 compensates for misalignment and, with its tapered bore and 52 mm outer diameter, offers an easy-to-fit solution.

The 1205-k-tvh-c3 self-aligning ball bearing from FAG is a double-row rolling bearing made from standard bearing steel. Thanks to the shared hollow-spherical raceway in the outer ring, the bearing self-aligns during operation. It compensates for misalignment and shaft deflection between the inner and outer rings. With an outer diameter of 52 mm and a width of 15 mm, this open design is suitable for lubricated assemblies in mechanical and plant engineering.

What is the 1205-k-tvh-c3 self-aligning ball bearing suitable for in operation?

The design proves its worth in bearing locations where elastic shafts or manufacturing-related misalignments lead to angular misalignment. The bearing is particularly suitable for use with long shaft spans prone to deflection. As the design is open at both ends, lubricant can reach both rows of balls unhindered. The integrated polyamide cage guides the rolling elements quietly and retains its dimensional stability within a temperature range of -30 to +120 °C.

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

The suffix ‘K’ denotes the tapered bore with a taper ratio of 1:12. This design allows mounting directly onto tapered shaft journals or, using a suitable adapter sleeve, onto smooth shafts. When slid onto the tapered seat, the radial clearance is reduced. The slightly increased factory-set radial bearing clearance (C3) specifically compensates for this press-fit process as well as thermal expansion during operation, ensuring that the required residual clearance is maintained.
