WPB Series Stainless Steel Spherical Bearing
SLB spherical bearings feature an injection-molded, PTFE-reinforced nylon race molded directly around a precision steel ball. This construction supports low-friction articulation in compact linkage positions while eliminating internal play and maintenance needs. The standard range covers 0.500 to 2.000-inch bores. Optional stainless steel ball or outer body configurations are available for corrosion-sensitive equipment.
Applications: Use SLB in precision linkage points, fabricated machinery joints, agricultural pivots, and light-to-medium duty industrial assemblies. Select stainless options when the bearing faces regular moisture exposure, and confirm complete assembly load requirements before installation.
