549-3113: Self Aligning Spherical Plain Bearing

Description: Self-aligning spherical plain bearings, such as part # 549-3113, 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. 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. Attributes: • Self aligning bearing • Inside Diameter: 70mm (2.756 in) • Outside Diameter: 120mm (4.725 in) • Outer Race Width: 45mm (1.77 in) • Inner Race Width: 59mm (2.323 in) Application: Cat self-aligning spherical plain bearings are typically used in applications where severe misalignment exists whether from mounting or shaft deflection or when the shaft may bend during operation.
