FCL elastic sleeve pin coupling is characterized by simple structure, easy to install, easy to replace, small size, light weight, which is widely used after installation and adjustment should the two axes can be maintained within the range of the relative displacement of the prescribed amount, the couplings have satisfactory performance and long working life. Therefore, the load is not widely used by a variety of motor-driven, low-power transmission shaft lines, such as gear, cranes, compressors, conveyors, textile machines, winches, ball mill. Elastic sleeve pin coupling allowable relative displacement: Radial displacement: 0.2 ~ 0.6mm angular displacement: 0 ° 30 '~ 1 ° 30 FCL elastic sleeve pin coupling in line with Japanese standard JISB1452, its simple structure easy installation, small size, light weight, maintenance-free, reliable quality, customers in Japan and other countries in the world in widespread use and appreciation
