Thrust roller bearings are compact bearings designed to rotate between parts and reduce friction. They are specifically built to handle axial loads in both vertical and horizontal shafts, effectively preventing shafts from drifting. These bearings typically consist of an inner ring, an outer ring, and rollers that taper into conical shapes. The raceways that the rollers interface with are angled to accommodate their tapered form. Thrust roller bearings are contained within a two-piece cage, ensuring that the rollers glide accurately. Their primary function is to support axial forces while allowing rotation, making them essential components in various applications, including automotive, industrial machinery, and heavy equipment.
