GN751.1 Fork Joint, Steel, with Rotating Shaft
Fork joints GN751.1 are similar to the fork head DIN71752 (Type A), but, unlike the DIN element, they have a rotating shaft and an additional bolt with axial shaft lock (Type KL and SL) which can be mounted and dismantled without tools.
The rotating shaft allows non-dynamic radial movements to be compensated, which may occur, for example, when using cable winches. Also, there is no need for the alignment of joint heads during assembly.
Steel - Tensile strength 500 N/mm2, zinc plated, blue passivated
Shaft safetys - Spring steel, hardened and tempered, zinc plated, blue passivated
