Self-Aligning Ball B. FAG 2313 -K-TVH-C3

FAG 2313 -K-TVH-C3 double-row self-aligning ball bearing with a tapered bore, C3 clearance and main dimensions of 65 × 140 × 48 mm for demanding industrial applications.

The FAG 2313 -K-TVH-C3 double-row self-aligning ball bearing automatically compensates for misalignment and shaft deflection during operation thanks to its hollow-spherical outer ring raceway. Manufactured from standard rolling-element bearing steel 100Cr6 in tolerance class P0/PN (ABEC 1), this open rolling bearing is designed for operating temperatures ranging from -30 to +120 degrees. The polyamide cage guides the two rows of balls with low friction and low vibration.

In which installation situations does the FAG 2313 -K-TVH-C3 prove its worth?

This self-aligning bearing is used when operational misalignments or shaft deflection need to be compensated for. In the case of rigid bearings, such misalignments frequently lead to edge loading, whilst the spherical outer ring raceway of this bearing automatically compensates for angular deviations. Typical applications include industrial shaft mountings with deflection or larger support spans. The open design, without abiding seals, allows for flexible lubrication with grease or oil via the housing design.

What is the function of the tapered bore and the C3 clearance?

The suffix ‘K’ refers to the tapered bore with a 1:12 taper, which allows mounting directly onto a tapered bearing seat or onto cylindrical shafts using clamping or withdrawal sleeves. The slightly increased radial bearing clearance C3 compensates for the reduction in radial clearance that occurs when the inner ring is slid onto the tapered fit. Furthermore, this clearance class accommodates operational temperature differences between the inner ring and the outer ring, thereby preventing undesirable stresses in the rolling element set.
