Realize non-coaxial transmission connection, transfer torque efficiently between two shafts with angular deviation. Made of material, durable and wear for long lasting performance. Widely used in a variety of machinery and equipment, such as excavators and joystick handle cross joints. Compact structure works stably in high speed rotation or multi axis linkage scenarios, reduces mechanical stress, extends service life. Check universal joints for wear or looseness, lubricate regularly, avoid impact and shock, replace damaged joints promptly.
