SKF® axial-radial cylindrical roller bearings for machine tool applications can accommodate axial loads in either direction simultaneously with radial loads or moment loads. Their unique internal design and high running accuracy (exceeding P4) additionally contribute to provide reliable support and precise positioning of rotating tables, indexing tables, and milling heads, among other applications.
Their design consists of an "L" shaped inner ring integrated with a shaft washer, an outer ring, two thrust roller cage assemblies, and a radial full complement roller row. Rollers are calibrated during assembly to impart appropriate preload and promote increased bearing service life, stiffness, and rotating accuracy while reducing noise levels.
Bore diameters range from 50mm to 400mm (for inner ring) and 120mm to 500mm (for outer ring). Bearings can be lubricated easily with grease or oil using dedicated lubrication holes located in the inner or outer ring or pre-lubricated bearings can be supplied to offer the proper amount of lubrication regardless of high or low operating speed.
Custom bearing solutions can be developed to satisfy particular application requirements.
