Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized jaw coupling manufacturer and custom jaw 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.

Zero/Low Backlash Jaw Style. Aluminum, Cast Iron, Steel, Stainless Steel hubs. Variable Durometer Urethane Elements. Bore Sizes 1/8" to 6". Rated up to 2,000 HP. Keyways are available in the oldham couplings as well. Shown here, alongside a jaw coupling with keyways. couplings are offered in seven sizes of set screw or clamp style hubs with bore from 1/8" (3mm) to 1" (25mm). The hubs are anodized for improved lubricity and increased life. The replaceable center discs are available in two materials to suit different applications. Nylon discs are compliant to dampen vibrations and reduce noise. Acetal discs are designed for precision applications requiring zero backlash and high torque capacity. Since the discs are replaceable, they may be used as a torque limiter. Comprised of aluminum hubs with drive tenons that mate to a torque transmitting plastic disc, their design allows for easy sliding to accommodate misalignment with a very light bearing load. Oldham couplings also have the advantages of electrical isolation, low inertia and a balanced design for higher rpm applications. While the couplings accommodate a small amount of angular and axial misalignment, they are especially useful in applications with parallel misalignment.
