Wound glass filament reinforced resin slip sleeve liner

In a low-friction axial bearing liner comprising a number of flat sides and intermediate corners forming a tubular structure having open ends and dimensioned to be inserted between rotationally driving and driven inner and outer elements and with some clearance therebetween for assembly and operating purposes such that only portions of the flat sides adjacent to the corners are subject to crushing by a torque load, a cured epoxy resin body forming said structure and having layers of helical glass filament reinforcing embedded therein, the inner layers extending around each corner being continuous from one end to the other end of the liner, the outer layers extending diagonally across the corners of the liner, the intermediate layers extending around each corner of the liner terminating intermediately of said ends thereof, said inner and intermediate layers providing the reinforcement of said portions of the liner against crushing by a torque load which may be applied to the liner in either direction while allowing limited distortion of the liner which is due to the geometrical displacement of the liner relative to the associated inner and outer elements resulting from their assembly and operating clearances.
