FAG Toroidal Roller Bearings Guide

Product Description

The C4126-XL-K30-V FAG toroidal roller bearing consists of an inner ring, outer ring, and long crowned rollers. Its internal geometry provides very high radial load capacity and self-aligning capability, while allowing axial displacement within the bearing. This helps accommodate shaft deflection, misalignment, and thermal expansion with low friction. In addition, X-life improves operating performance and service life, while the K30 tapered bore with a 1:30 taper supports mounting on suitable tapered shaft arrangements.

The C4126-XL-K30-V bearing is suitable for paper machinery, steel and metallurgy, mining and cement, power generation, material handling, and heavy industrial equipment. Its high radial load capacity and self-aligning capability support demanding radial loads and shaft deflection. Meanwhile, its internal axial displacement capability helps compensate for thermal shaft expansion, making it especially suitable for bearing arrangements where radial loading, misalignment, and axial displacement occur together.
