Spherical Bushings

A spherical bushing is a plain bearing built around a spherical inner ring inside a cylindrical outer ring. The geometry lets the inner ring swivel inside the housing, so the joint accepts angular misalignment without binding. Hardened steel-on-steel construction handles high static and shock loads in equipment where rolling-element bearings would not survive. PTFE-copper-mesh liner is available for maintenance-free service.

• High static load capacity. Steel-on-steel contact across the spherical surface spreads load over a large area, with static ratings reaching 26,500 kN on the largest sizes.
• Self-aligning by design. The inner ring swivels inside the spherical housing, so the joint stays free even when the mating shaft tilts under load.
• Steel-on-steel or maintenance-free. GS, ES, and SB series run steel on steel with relubrication. EC-suffix series use a PTFE-copper-mesh liner for maintenance-free service.
