066-5815: 57.15mm Inner Diameter Self Aligning Bearing

Description: Cat bearings are designed for specific applications based on load, operating speed, temperature range, size, and past performance and are manufactured to the highest quality standards for long life and performance. Self-aligning spherical plain bearings consist of an inner convex race and an outer concave race that swivel to eliminate stresses on the shaft and bearing assembly due to deflection. Caterpillar design engineers match the right combination of dimensions, materials, surface finish, and manufacturing processes, to each part to enable them to work and wear effectively with all the other neighboring and dependent parts. Attributes: • Lubrication grooves and holes • Single or double fracture outer race • Outer Race Length: 42.85 mm (1.687 in) • Spherical Diameter: 82.17 mm (3.235 in) Application: Cat self-aligning spherical plain bearings are typically used where misalignment, high radial loads and bi-directional axial loads are present.
