Self-Aligning Ball B. FAG 2305 -K-TVH-C3

The FAG 2305 -K-TVH-C3 double-row self-aligning ball bearing compensates for angular misalignment and, with dimensions of 25 x 62 x 24 mm, offers flexible mounting options.

The 2305 -K-TVH-C3 self-aligning ball bearing is a double-row rolling bearing from FAG, manufactured from standard rolling bearing steel (100Cr6). Thanks to the hollow spherical raceway in the outer ring, the ball assembly aligns itself automatically when the shaft deflects. This open bearing features a tapered bore and a lightweight polyamide cage. With dimensions of 25 mm bore diameter, 62 mm outer diameter and 24 mm width, it is suitable for industrial applications where misalignment between the shaft and housing may occur.

What is the 2305 -K-TVH-C3 self-aligning ball bearing suitable for in operation?

The use of this self-aligning bearing is particularly recommended where elastic shafts or housing deflection cause static or dynamic angular misalignment. As the inner ring, together with the two rows of balls, can pivot within the outer ring, the design compensates for misalignment during operation without generating additional edge pressure. The open design allows for direct lubricant supply via the surrounding system. Typical applications include industrial shaft bearings operating at medium speeds and under varying radial loads.

What do ‘tapered bore’ and ‘C3 clearance’ mean during assembly?

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design allows for mounting on tapered shaft seats or, with the aid of mounting and withdrawal sleeves, on cylindrical shafts. When the inner ring is pushed onto the shaft, it expands, thereby reducing the operating clearance. The factory-specified bearing clearance class C3 provides increased radial bearing clearance. This clearance accommodates expansion during tightening as well as thermal expansion within the permissible temperature range of -30 to +120 degrees.
