XCMG BR750 Crane Wheel Hub
This wheel hub is listed for compatible XCMG BR750 crane wheel-end assemblies. It supports the wheel and bearing arrangement and provides the mounting interface for the wheel fasteners. Because axle position and production configuration can change the hub specification, comparison with the removed part is required.
Identification and Matching
Crane model, serial number and production year
Front, middle or rear axle position and left/right location
Original XCMG part number or casting marks
Wheel-stud quantity, bolt-circle diameter and thread specification
Inner and outer bearing-seat diameters and spacing
Oil-seal running surface and overall hub width
Brake-drum or disc mounting interface
ABS tone-ring or sensor arrangement when fitted
Application and Service Scenarios
A replacement hub may be required after confirmed cracking, damaged wheel-stud holes, worn bearing seats, distorted mounting faces or seal-surface damage. Symptoms such as wheel play, bearing noise, overheating or oil leakage can also result from incorrect bearing adjustment, failed bearings, seals, axle components or lubrication loss, so the complete wheel end should be inspected before ordering.
Workshop Inspection
Clean the removed hub and check for cracks, fretting, scoring and heat discoloration. Measure bearing fits and sealing surfaces rather than relying only on visual similarity. Inspect the spindle, bearings, wheel studs, brake components and lubricant for metal contamination. Record the installed orientation before disassembly.
Installation and Commissioning
Use the specified bearings, seals, lubricant and tightening procedure from the applicable XCMG service information. Keep bearing and seal surfaces clean, replace damaged fasteners, and set bearing preload or end play correctly. After installation, rotate the wheel by hand, check for drag and play, then perform a controlled road test and recheck temperature and leakage.
Frequently Asked Questions
Can a BR750 model name alone confirm the hub?
No. Axle position, machine serial number, casting reference and dimensions must also match.
Should bearings and seals be inspected during hub replacement?
Yes. A damaged bearing or seal can cause repeat failure and should be evaluated as part of the wheel-end repair.
Can a similar bolt pattern prove interchangeability?
No. Bearing seats, offset, brake interface, seal surface and axle fit may still differ.
What photos and measurements are most useful?
Provide both hub faces, casting marks, wheel-stud pattern, bearing bores, seal surface and the crane and axle identification plates.
Export Packing
Bearing bores, threads and sealing surfaces are protected against impact and corrosion. The hub is secured in a reinforced crate and labelled with the confirmed machine and axle position.
