C 31/1000 KMB

The C 31/1000 KMB is a high-performance CARB toroidal roller bearing designed to handle demanding industrial applications with unique alignment challenges. This bearing combines the self-aligning capability of a spherical roller bearing with the unconstrained axial displacement of a cylindrical roller bearing. It features a single row of long, slightly crowned rollers and a robust machined brass cage (MB) centered on the inner ring. The "K" in its designation signifies a 1:12 tapered bore, which allows for secure and precise mounting on a shaft using an adapter or withdrawal sleeve.

The principal advantage of the C 31/1000 KMB is its ability to manage both angular misalignment and significant axial expansion within the bearing itself, eliminating induced internal stresses. This unique function prevents premature wear and ensures a longer operational life, especially in applications with long shafts that experience thermal elongation. The toroidal design maintains an optimal load distribution across the rollers, reducing friction and operational temperatures. This leads to higher reliability, lower energy consumption, and reduced maintenance requirements.

Engineered for heavy-duty locating/non-locating bearing arrangements, the C 31/1000 KMB is an ideal solution for long-shaft applications where thermal expansion is a critical factor. It is frequently employed in demanding industrial settings such as paper machines, continuous casters in steel mills, large industrial fans, and long conveyor systems. By accommodating both misalignment and axial movement in a single compact position, this CARB bearing enhances the overall reliability and efficiency of critical machinery, preventing costly downtime.
