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.
