description

This 252904937 tooth sleeve is specially matched for bucket teeth of our mining bucket series. It is cast from wear-resistant alloy steel and treated by quenching and tempering. It features high surface hardness and good core toughness with excellent resistance to impact and spalling. The inner taper design fits tightly with bucket tooth head for stable installation and easy replacement. When digging hard rock such as limestone and granite, the sleeve acts as the front sacrificial part to absorb rock impact and friction and protect the base bucket tooth. It matches bucket teeth for mining bucket 252110006 and 252110032, forming a complete tooth assembly together with pins and cotter pins. Every batch is inspected for dimension, hardness and surface defects to avoid casting faults such as pores and cracks, ensuring uniform load distribution.

product parameters

Product Name: Tooth Sleeve for Mining Bucket Teeth
Part No.: 252904937
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Matching Parts: Teeth of mining rock bucket
Material: Wear-resistant alloy steel (quenched and tempered)
Matching parts: Bucket tooth, pin, cotter pin
Installation: Taper interference fit on the front of bucket tooth
Working Condition: Quarry, hard rock digging, crushed stone handling, crusher feeding
Inspection Items: Dimension inspection, hardness sampling, surface crack inspection

Applicable Scenarios

It matches 2.5m³ and 2.7m³ mining rock buckets for XCMG ZL50G and ZL50GL, widely used in quarry and crusher feeding. It is located at the foremost cutting position and bears direct rock impact. Earth and light-material buckets usually do not adopt this heavy-duty tooth sleeve assembly.

advantage

- OEM taper design ensures precise fit with bucket tooth head, uniform clearance and anti-slip performance. No on-site grinding required to save installation time
- Integrally quenched alloy steel balances wear resistance and toughness, resisting spalling under repeated rock impact for stable service life
- Split replaceable structure, only the worn sleeve needs replacement instead of the whole tooth, greatly reducing spare part cost and capital occupation
- Optimized casting process ensures dense internal structure, less casting defects and better fatigue resistance under cyclic impact
- Front sacrificial layer isolates rock impact and protects expensive bucket tooth base, extending the service life of bucket teeth
- Fully compatible with our mining tooth, pin and edge protection parts, convenient for stocking and bulk delivery

FAQ 

Q：Can this tooth sleeve fit bucket teeth of other brands or models?
A：No. The inner taper and cavity dimension are custom-designed. Mismatched fit causes loosening, cracking and damage to bucket teeth.

Q：Can chipped sleeve keep working?
A：Not recommended. Chips create stress concentration. Cracks spread rapidly under impact and accelerate tooth wear. Replace promptly.

Q：Why does the sleeve fall off after installation?
A：Common causes: worn tooth head, dirt and rust on taper surface or deformed contact face. Clean mating surface before assembly. Replace severely worn bucket teeth.

Q：Can I repair worn sleeve by welding?
A：Not recommended. Welding heat destroys quenched layer, leading to uneven hardness and much shorter service life.

Q：What to check when receiving goods?
A：Verify part number, check cracks, casting defects and deformation, inspect inner taper surface and test fit with matched bucket tooth.
