Applicable Scenarios

It matches the 252109208 rock bucket on XCMG ZL50G and ZL50GL loaders, widely used in quarries, stone crushing plants and rock foundation excavation sites for limestone, granite, boulders and compacted hard soil. It only fits this specific welded sleeve-tooth bucket and cannot be used on earth buckets or ordinary bolted tooth bases.

- OEM matched dimension, perfect interchangeability for 252109208 bucket tooth base and sleeve teeth
- High-chrome alloy with surface hardening delivers outstanding bore wear resistance under continuous rock abrasion
- Precision casting ensures good alignment of bore and pin hole, smooth tooth fitting and less pin jamming
- Modular spare part; replace sleeve only instead of cutting and re-welding the whole tooth base
- Gradient hardness structure: hard surface for wear resistance and tough core for impact resistance against brittle fracture
- Compatible with matching sleeve teeth, easy unified spare part management
- Strict casting defect inspection with stable batch quality for reliable continuous quarry operation

FAQ 

Q：Can this tooth sleeve fit other types of rock buckets?
A：It is not universal. It is specially designed for 252109208 welded sleeve-tooth bucket. Outer diameter and locating dimension are exclusive. Mismatched installation causes tooth wobble.

Q：Can I keep using the sleeve if the inner bore is scored and grooved?
A：Scored bore changes fit clearance. Loose tooth generates cyclic shock on lock pin, leading to frequent pin breakage and accelerated tooth root wear. Replace it in time.

Q：Why are sleeve teeth often stuck and hard to remove?
A：Sand and rock debris trapped on mating surface, sleeve deformation or out-of-round bore are main causes. Clean debris before assembly. Replace deformed sleeves directly.

Q：What should be noticed when welding the sleeve?
A：Remove rust and grease before welding. Use wear-resistant welding material and control heat input to avoid annealing. Perform NDT inspection after welding.

Q：Can cracked tooth sleeve be repaired by welding?
A：Welding repair is not recommended. Heat destroys the hardened layer. The repaired section loses wear resistance and is prone to re-fracture under heavy impact.
