Notes: (1) r1 smin or r2 smin stands for the minimum allowable value of chamfer r1 or r2.
(2) When spherical bushing are used with the full tilting angle, the shoulder height must be less than this value.

Material
Inner & Outer RinEC: Hard Bearing Steel.
Maintenance-Free Liner: Maintenance-free Spherical Bushings consist of an outer ring which has a special PTFE liner reinforced with a copper alloy mesh on the sliding surface, and a spherical inner ring of which sliding surface has hard chromium plating. Creep deformation due to compressive load is small, and wear resistance is superior. Thus, they have a long life and can be used for extended periods of time without relubrication. They are especially suitable in cases where fixed directional loads are applied and are used mainly in food processing machines and construction machinery and in other applications in which the use of oil is undesirable or lubrication is not possible.
Seal: Synthetic Resin

Other Info.
Creep deformation due to compressive loads is small, and wear resistance is superior.
These bushings are used as maintenance-free bushings.
