C 3138 KV-CARB Circular roller bearing-FGFA bearings

C 3138 KV Full complement CARB toroidal roller bearing with tapered bore (1:12)

CARB spherical roller bearings are components that combine self-aligning capabilities with load-bearing advantages. They automatically compensate for misalignment between shafts and bearing housings while reliably sustaining radial loads and bidirectional axial forces. Characterised by high rigidity and superior impact resistance, they are well-suited for medium-to-high-speed applications. Featuring low friction coefficients and smooth operation, they also offer straightforward maintenance.
