Summary:Universal coupling (WSD, WS, WSS, WSF)-used for transmission occasions where the angle between two axes on the same plane of the connection space is β≤45°.It can be divided into single cross type, double cross type, retractable type and flange type.

　　Universal coupling (WSD, WS, WSS, WSF)-used for transmission occasions where the angle between two axes on the same plane of the connection space is β≤45°.It can be divided into single cross type, double cross type, retractable type and flange type. SWPF type large telescopic single universal coupling has the characteristics of large transmission torque, long service life and wide application range.Its application especially provides favorable conditions for the technological transformation of the metallurgical industry and the upgrading of mechanical products.
