COM-T Series Stainless Steel Spherical Bearing
COM-T spherical plain bearings add a PTFE liner to the commercial-series metal-to-metal platform. The precision-ground 52100 bearing-steel ball runs against an alloy-steel race with a liner for low-friction articulation without routine greasing. The inch-size range covers compact linkage joints and larger radial pivot points. Stainless race and ball configurations can be reviewed for corrosion-sensitive assemblies.
Applications: Choose COM-T for suspension links, chassis pivots, agricultural control points, and industrial linkages where maintenance access is limited. The PTFE-lined construction fits dry, oscillating movement, but you should confirm load, temperature, and chemical exposure before final selection.
