Supply Taishun Z7A expansion sets (JB-T7934-1999)

The Taishun Z7A expansion sets (JB-T7934-1999) http://www.wzlmjx.com/products_view.asp?id=1921 expansion sets are widely used in today's international parts and shaft coupling, by tighten 12.9 high strength screw inclusive generated between the surface pressure and friction to a novel keyless links to achieve the load transmission means. Swelling link sets as a state-of-the-art infrastructure, the eighties industrial countries such as Germany, Japan, the United States under the heavy load mechanical coupling extensive use of this new technology. Pressure and friction of the wheel and the shaft coupling, it is so that by tightening the high strength bolts inclusive generated between the surface to achieve a keyless coupling means for load transfer in order to achieve mechanical parts (such as gears, flywheels, pulleys, etc.) shaft coupling to transfer load. It uses high strength bolts, between the inner ring and the shaft the huge hold fast to force generated between the outer ring and the hub; when under load, by the expansion sets and combination of mechanical pressure and accompanying friction transfer torque, axial force, or both combined loads Recommended products: expansion sets http://www.wzlmjx.com/
