Pingyang Z5 expansion sets (JB-T7934-1999) http://www.wzlmjx.com/products_view.asp?id=1924 why link expansion sets can withstand multiple load? Expansion sleeve coupling can withstand multiple load, The structure can be made into a variety of styles. Depending on the size of the installed load multiple expansion units can also be used in tandem. Coupling expansion sets will lose a coupling role overload, to protect equipment from damage. Expansion sets of long life, high strength. Expansion sets rely on friction drive, no keyway weakened, and it no relative motion of the coupling member, the work will not wear Recommendations: expansion sets http://www.wzlmjx.com/
