Installation Location: Mounted at the top yellow large disc of the clamp, connecting the crane hook above and the clamp body below.
For general industrial workshop environments with dust and continuous operation:
Adopt single-row four-point contact ball slewing bearings or single-row crossed roller slewing bearings to balance cost and load capacity;
Equip with an automatic centralized lubrication system that automatically replenishes extreme-pressure lithium-based grease every 100 working hours, reducing maintenance costs;
External gear design facilitates easy installation and maintenance of drive units, meeting routine workshop inspection and repair requirements.
Improve operational efficiency: 360° rotation expands the lifting coverage, eliminating the cumbersome repeated movement of the crane hook in traditional operations, boosting lifting efficiency by 30%-50%;
Ensure operational safety: Precise positioning reduces the risk of cargo collision and swaying, lowering equipment and material damage, and cutting failure rates by over 70%;
Extend equipment service life: Rolling friction reduces energy consumption and wear on transmission components, with a slewing bearing service life of over 100,000 hours, far exceeding traditional roller-type mechanisms.
Customer Pain Points | Solutions with Slewing Bearings |
Inaccurate positioning & slewing jamming of lifted loads | High-precision gear meshing + high-rigidity raceway design, positioning accuracy ±0.1°, effectively eliminates jamming |
Equipment swaying and overturning risk under heavy-duty operation | Three-row roller structure withstands large overturning moment, suitable for heavy lifting of 80 tons and above |
Seal failure caused by workshop dust and salt spray | Triple anti-corrosion sealing design, adapts to harsh environments and extends maintenance intervals |
Oversized and heavy trolley design | Lightweight crossed roller structure, reduces equipment size by 20%, fits limited workshop space |
