28×70 Oil-free Universal Joint

It is in a cross-shaped structure, consisting of the cross shaft and four journal necks as key components. Each journal neck precisely cooperates with the main body of the cross shaft, enabling flexible rotation at different angles, meeting the requirements of variable angles during power transmission. The design without oil holes simplifies the structure, reduces the potential risks of leakage and blockage caused by oil holes, and also reduces the weight of the components. It is forged from high-strength alloy steel, and this material undergoes a special heat treatment process, possessing excellent strength, hardness and wear resistance. It can maintain stable mechanical performance under conditions of large torque and alternating loads, effectively resisting wear and fatigue damage, and ensuring the reliable operation of the universal joint in complex working environments. It can work normally in various harsh working conditions, whether in high-temperature, low-temperature environments, or in dusty, humid and other harsh conditions, by virtue of its sturdy structure and high-quality material, maintaining stable performance and being widely applied in various types of mechanical equipment.
