The GLG Series freewheels are particularly suitable for applications requiring long operation times in neutral at high speeds. These have the same bodies as the GL series but a cage of the GP series is mounted inside which makes it possible for the bodies to detach when running in neutral to reduce wear. Flanges are from the GL series, see pages 32 to 37 for dimensions. Models with holes 70 and 80 are produced by modifying only the internal ring of the GLG60/GL2G60, for which the same kind of flanges are mounted. The torque forces are transmitted from the shaft to the inner race by means of a key and from the outer race to the external area by means of screws. Shaft tolerances must be h6, whilst tolerances for the driven part must be H7. Grease lubrication with a labyrinth seal allows a high reduction of heat due to oil movement and friction between sealing rings. Each freewheel is supplied with paper gaskets (without paper gaskets, the freewheel can be seriously damaged).
