Construction Machinery
Cross-type universal joints are widely used in loaders and cranes, primarily connecting the gearbox to the drive axle or the rotary support to the reducer. Loaders operating on construction sites face bumpy ground, causing constant changes in the relative position of the gearbox and drive axle. 6H2577 Dual cross-type U-joint configurations with sliding splines compensate for both angular misalignment and axial displacement. For cranes, 6H2577 joints withstand complex loads including axial force and overturning torque, maintaining stable power transmission even when the boom swings within ±10 degrees. Reinforced bearing caps and thickened cross shafts enable them to handle high-impact loads in harsh construction environments.

| The surface hardening layer depth of the outer raceway of the bearing needs to be inspected. |
| The machined parts of the cross shaft and the shaft sleeve must undergo burn test. |
| The rotational flexibility of the needle roller bearings must be tested. |
| The axial clearance of the needle bearings in the assembly needs to undergo type testing. |
| The logo on the cross-axis product should be printed on the non-machined surface. |
