With an impressive temperature range and included installation accessories, this boot kit is perfect for both single and double joint applications. ## Description This Curtis universal joint boot kit with one neoprene boot and two nylon ties helps retain lubricants and provides protection against contaminants to extend the life of the universal joint. The universal joint boot is suitable for grease packing with both intermittent and continuously rated joints, and is made of neoprene for high tensile strength and resistance to abrasion and tearing. Neoprene is compatible for use with ozone, sunlight, ammonia, Freon, and some hydrocarbons, and maintains flexibility over a wide temperature range from -60 to +220 degrees F. The boot slides over the joint and is secured into position on either grooved or smooth joints with the nylon ties (included). The boot can be used in pairs to protect double universal joints. Belden universal joints are suitable for use in various consumer and industrial applications, including drilling and tapping machine tools, pumps, textile machinery, and medical and optical devices. Universal joints (also called U-joints, universal couplings, Cardan joints, Hooke’s joints, or Hardy-Spicer joints) are used to transmit motion and rotational power, or torque, between two shafts that are offset at an angle. Most universal joints consist of two yokes and a middle assembly; the hub end of each yoke attaches to a shaft while the yoke ears attach to and pivot around the middle assembly to accommodate shaft misalignment. The type of middle assembly determines its usage—pin and block joints are suitable for transmitting high torque, needle bearing joints are used to handle high rotational speeds, and ball and socket joints are used in applications requiring low backlash (play between moving parts). The body of the universal joint may include a single joint to accommodate only angular misalignments between shafts, or two joints to accommodate both angular and parallel misalignments. Available in a variety of materials and configurations, universal joints are used in applications including motor vehicles, conveyors, medical and optical devices, forestry and mining equipment, robotics and space exploration, and aeronautics, among others. Curtis Universal Joint Company manufactures universal joints and assemblies for military, commercial, industrial, and medical applications. The company, founded in 1935, is headquartered in Springfield, MA.What’s in the Box?
