This shaft coupling has listed as national standard GB5272-85, is suitable joins in each kind of machinery two with the spindle rotation,Has in a big way compensates two axes relative displacements, the cushion, the absorption of shock, oil resistant, bears the air to get older, wear-resisting and so on the performance, the structure reasonable, the service convenient, the components few, the compatibility strong, the service life is long and so on the characteristic.The operating temperature for -35~80°C, the short-term operation temperature may reach 100°C, the transmission nominal torque is 16~25000N.M.
