GEP 260 FS

GEP 260 FS

Radial spherical plain bearing, maintenance-free, metric sizes

These radial spherical plain bearings have a steel/PTFE FRP sliding contact surface combination.

They are factory greased and maintenance-free. However, relubrication can extend bearing service life and can be applied via lubrication holes and an annular groove in both rings. Compared to the GEC design (axially split outer ring), the GEP design (radially split) has a wider and larger outside diameter for a given shaft size. This results in a higher basic load rating, but a smaller tilt angle.

Designed for radial and combined radial and axial loads
Long service life and maintenance-free
Relatively insensitive to contaminants
Low coefficient of friction
