Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized pin coupling manufacturer and custom pin couplings designer of various kinds of conveyors, belts, pulleys, bearings, rollers, bushings and so on. Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

Ever since Elecon's inception in the year 1951, it has strived to reach new frontiers of Technical excellence. Wide range of Worm, Helical, Spiral Bevel Helical gears Flexible, Geared and Fluid Couplings. Elecon designs & manufactures a wide range of worm, parallel shaft and right angle shaft helical and spiral bevel helical gears with horizontal and verticle output shafts in various sizes, from single to quadruple stage reduction.
Elecon gears are compact and light weight, saving space, reducing foundation structure costs and lubricating oil consumption.Flexible coupling is a cushioned drive type, transmitting the torque through rubber bushes which have excellent capacity to absorb shocks. LT100 elastic sleeve pin coupling £¨GB/T4323-2002£©. structure characters: Because of the clearance between elastic sleeve and round holes on the flange of semi-coupling and deformation of elastic sleeve, the coupling has compensation of both relative offset and damping property. Working temperature: -20¡æ¡«+70¡æ. Forms, dimensions, and marks of shaft hole and keyway correspond to GB/T3852-1997(connecting forms and dimensions of coupling shaft hole). Marked example: LT105 elastic sleeve pin coupling. Drive end: Z shaft hole, C keyway, d=30mm,L=60mm. Driven end: Y shaft hole B keyway, d=28mm,L=62mm

ROTOPIN Pin Bush Type Couplings are in use in general industrial applications over many years and are quite useful in drives where limited misalignment of shafts is unavoidable. ROTOPIN Flexible Coupling comprises two Hubs in Cast Iron of high quality and a variable number of flexible elements, depending on the power to be transmitted. The flexible elements of rubber bushes are capable of damping vibration and shock loads as well as accepting misalignment that inevitably occurs between rotating shafts which are independently supported. A ROTOPIN Flexible Coupling is suitable for rotation in either direction and does not require lubrication. Rubber used for manufacture of bushes is of high quality and works as a safeguard against any bad effect of water, dust and atmospheric conditions. The original bushing is a neoprene elastomer with a graphite impregnated bronze sleeve. These are still available, as well as a contemporary version of this concept: urethane bushings. Renold also manufactures many custom variations of this coupling including brake drum and shear pin type couplings. The pin bush coupling manufactured by us consists of a set of high quality rubber with pins and nuts and two flanged hubs of graded cast iron. This type of coupling permits drive in either direction and requires neither lubrication nor adjusment after fitting.
