Precision wear-resistant components for demanding environments
Our Tungsten Carbide Sleeves are designed for industrial customers who need precision wear components for severe wear applications. Manufactured from high-quality tungsten carbide, these sleeves offer outstanding resistance to abrasion, erosion, and mechanical wear.
Tungsten Carbide Sleeves are precision wear-resistant components used in high-wear, high-pressure differential, and high-media erosion situations. They are often used as key elements in pumps, valves, bearing supports, guide bushings, and rotating friction pairs.
Manufacturing & Quality Control
Our tungsten carbide sleeves are manufactured with attention to material consistency, dimensional accuracy, hardness control, and wear performance.
- Coaxiality control of inner and outer circles
- Sintering shrinkage compensation for thin-wall structures
- Inner hole surface roughness and dimensional stability
- Control of cracks, edge chipping, and edge defects
- Assembly matching control with mating shafts and metal seats
Selection Recommendations
Choose the right sleeve for your application:
- **High-particle wear media**: prioritize grades with higher wear resistance
- **Corrosive media present**: comprehensively evaluate binder phase system and seal structure
- **High-speed rotating applications**: focus on controlling coaxiality, surface roughness, and fit tolerances
- **Press-fit structures**: avoid excessive interference that may cause brittle fracture
