Slewing bearings (also called slewing rings, slewing ring bearings, slew bearings, slew rings, slew ring bearings, swing bearings, turntable bearings) are machine elements that can simultaneously transmit axial and radial forces as well as tilting moments.
LYXQL can produce slewing bearings with outer diameter from 1500mm to 17000mm.
Crawler crane refers to a fully rotating boom crane with crawler walking device. The lifting capacity is large, and it can be lifted and walked. It has strong lifting capacity. It is troublesome to disassemble and assemble, suitable for large-scale factories to work in the factory area.
Three row roller slewing ring bearings are usually used for crawler cranes to carry larger axial load, larger radial load and tilting moment.
As the most critical and deadly core component of the rotating mechanism, slewing bearings’ material, heat treatment, rotation accuracy, gear accuracy and reliability must to be produced carefully.
The most basic maintenance and daily maintenance include gear lubrication and raceway lubrication of the swing bearing.
The initial performance of the failure is a sudden frustration, sharp noise and obvious inflexible rotation, it needs to hit the throttle to barely rotate, or even break the pinion or slew bearing gear. If there are no obvious faults in the bearing, the matched pinion meshing needs to be adjusted.
