Established in 1998, China Xiaowei Bearing Co., Ltd. is a high-tech enterprise specializing in spider coupling manufacturer and design many kinds of bearings. We have a modernized staffs of tech research and fog machine development, ISO9001 certificated, and manufacturing adopts advanced domestic and foreign standards such as GB, API, JIS, DIN, BS, NF and ANSI. Our custom spider couplings are exported to countries and regions in Europe(UK, France, Italy, Germany), North America(USA, Canda), the Middle East and Southeast Asia.

vibration damping. electrically insulating (standard).backlash-free. press-fit design. compensation for misalignment. Safety overload couplings are used to allow for a certain amount of slippage to occur in order to prevent damage to the drive or machinery when torque exceeds a certain preset limit. These couplings consist of the following parts: A set of springs is used to apply force (springs are rated in newton/meters) to the brake linings. The springs are specific to the drive application, and cannot be substituted with other types of springs. A pair of brake linings, similar to the brake linings found in automobile drum brakes. An external drum. The brake linings are held to the inner surface of the drum by friction and pressure applied by the springs. An internal hub to hold the springs and linings together and transfer power to the brake linings. These parts are available from us separately or we can supply the entire safety overload coupling.

This product has been the European standard jaw coupling, as well as in many other parts of the world. The three-piece design incorporates a radial curvature to the jaw face, and both radial and axial curvature (crowning) to the elastomer (spider). The Curved Jaw Coupling provides highly reliable service for light, medium, and heavy duty electrical motor and internal combustion engine power transmission applications. Curved Jaw Couplings are distributed worldwide to support OEM`s and the users of their equipment. Improved torsional softness. Angular misalignment capability of up to 1.3. No lubrication required. No metal-to-metal contact. Fail-safe � will still perform if elastomer fails. Easy installation.
Three shore hardnesses of urethane open center type elastomers available. Urethane spiders provide high abrasion resistance and elasticity, along with good. damping characteristics. Resistant to oil, dirt, sand, grease, moisture, many solvents, as well as the atmospheric effects of ozone. Both rough stock bores and finished in/metric bores available. Torque range of 35 in-lbs to 66,375 in-lbs
