Customized high level XR/JXR series Crossed tapered roller bearings
Crossed tapered roller bearings (XR/JXR series) are designed to offer the highest levels of rotational accuracy and rigidity while conserving space. The bearing features two sets of rollers bring together at right angles with alternate rollers placing in opposite directions. It is uniquely suited to many other applications where space is limited.
Application fields of the our slewing bearings:
The turntable bearing produced by our company is used in dock fixed crane, Marine floating crane, gantry crane, ladle rotary table, bucket wheel stacker and reclaimer, circular stacker and reclaimer, crawler crane, ferris wheel, rotary test bench, segment erector, bottle blowing machine and other fields.
