Self-Aligning Ball B. FAG 2317 -K-M-C3

The 2317 -K-M-C3 double-row self-aligning ball bearing reliably compensates for misalignment and, with dimensions of 85 x 180 x 60 mm, features a sturdy brass cage and C3 clearance.

The 2317 -K-M-C3 self-aligning ball bearing from FAG Wälzlager is a double-row rolling bearing made from standard bearing steel (100Cr6). Thanks to the hollow-spherical outer ring raceway, the bearing automatically adjusts itself in the event of shaft deflection or misalignment. This open bearing features a tapered bore with a 1:12 taper and tolerance class P0/PN or ABEC 1. It is suitable for industrial applications involving combined radial and axial forces.

In which applications does the 2317 -K-M-C3 self-aligning ball bearing compensate for misalignment?

Design engineers primarily select this design for long shafts or split housing bodies where misalignment occurs as a result of the manufacturing process. The double-row bearing compensates for angular misalignment between the inner and outer rings during operation without generating excessive friction. Typical applications include shaft mountings with deflection or misalignment. As this is an open design, lubrication is provided flexibly via the surrounding housing system.

What are the advantages of the brass cage and tapered bore in the 2317 bearing?

The suffix ‘M’ denotes the brass cage. This cage guides the balls accurately even under vibration or shock loads and is designed for a temperature range of –30 to +150 degrees. The tapered internal bore with a 1:12 taper facilitates mounting on tapered shaft seats or, using clamping or withdrawal sleeves, on cylindrical shafts. Thanks to the slightly increased C3 radial bearing clearance, sufficient radial operating clearance remains even after press-fitting.
