The M5-36P1Z Trailer slewing bearings (lightweight slewing bearings) are mainly composed of thin-walled inner and outer rings, steel balls or rollers, spacers, and sealing devices. Mounting holes are provided on the inner and outer rings for bolt connection; some models can integrate gears. They feature a compact structure, lightweight design, and small cross-sectional dimensions.
Trailer slewing bearings are lightweight, rotate flexibly, and are easy to install and maintain. They can simultaneously withstand axial loads, radial loads, and overturning moments, possessing excellent load-bearing capacity. Direct bolt fixing eliminates the need for complex mounting seats, simplifying the connection structure between the trailer chassis and the superstructure.
