YANGZHOU LASTE MECHANICAL ENGINEERING CO., LTD. located in Yangzhou Jiangshu China. is an enterprise specialized in mechanical drive design and manufacture. With rich production experience rooted in years of professional R&D of various shaft couplings, as well as favorable and unparallel advantages in R&D of high- and new-tech competitive products and bulk production, we can guarantee all our products manufactured in line with international and industry standards. And we also provide non-standard coupling products of reliable & stable quality in complete specifications, so as to meet the demand for updating and reforming mechanical products of various kinds, and to promote the shaft couplings up to requirements of different imported machinery. Our products have been widely applied in many industries related to mechanical drive in over 20 provinces and cities nationwide, and also exported to Czechoslovakia, Australia, Pakistan, Corea, Columbia, Venezuela, Canada, Russia, South Africa, Thailand, Taiwan, Hongkong, Egypt, Malaysia, Greece, Turkey, Singapore, Iran, India, Indonesia, Vietnam, Israel etc, more than 20 countries and regions abroad, mainly used for metallurgical machinery, steel-rolling machinery, universal machinery and some other heavy machinery.
The main products: Cardan shaft, Universal joint, Cross joint, Shaft coupling, universal coupling, universal shaft, propeller shaft, Gear Coupling, Grid Coupling, Disc Coupling, Flexible Coupling, Chain Coupling etc.

The universal coupling is a kind of shaft coupling that permits large-angle displacement between the shafts, specially used for connecting shafts in that condition. The compact design of radial external dimension ensures convenient maintenance, large transmitting torque, high efficiency, long service life and low noise during working. Driving of intersecting shafts can be delivered. The large-designed shaft angle can be altered during its running and the maximum shaft angle can reach 35 - 45 degrees. When a single universal coupling is used, the speed of driven shaft will fluctuate periodically. And this is mainly used for the transmission connecting of the intersecting shafts. Due to such features as large deviation angle and transmitting torque, the universal couplings are widely applied in Metallurgical machinery, steel rolling machinery, mining machinery, textile machinery, paper machinery, cement machinery, hoisting and conveying machinery, petroleum machinery, electrical machinery, chemical machinery, shipbuilding, etc. various conditions of universal machinery and heavy machinery.
