Product Overview
This is a tungsten carbide bush or sleeve designed for wear protection in high-abrasion and corrosive environments. It is pressed on an imported press and sintered in an over-pressure sintering furnace to achieve consistent density and small dimensional tolerance. The part is made to the buyer's drawing and is used in valves and bearings to reduce leakage and wear. It is suitable for submersible oil pumps, slurry pumps, water pumps, and centrifugal pumps in the petrochemical industry.
Key Benefits
- Long service life due to exclusive raw material formula with wear-resistant additives
- Stable quality with good density and high comprehensive performance
- Lower processing cost because of small tolerance margin on boundary dimensions
- Chemically stable against acid, alkali, alcohol, ether, hydrocarbons, oil, detergent, and sea water
- Fast delivery due to complete mold inventory and short production cycle
Technical Data
Values below come from the product data we publish. Anything not listed is confirmed against your drawing at quotation.
| Material | Cemented tungsten carbide (WC-Co) |
|---|---|
| Shaping | Pressed and sintered from existing or new moulds |
| Finish | Ground to drawing |
| Dimensions | To customer drawing |
| Lead Time | Stock items 3-5 days after payment; customised items quoted per order |
| Grades Available | YG6 YG8 YG10 YG15 YL10.2 and equivalents, selected against the service conditions |
Problems It Solves
- Steel or bronze bushings wear out quickly in abrasive or corrosive fluid, leading to frequent pump teardowns
- Clearance increases between shaft and sleeve as wear progresses, causing leakage and reduced efficiency
- Large dimensional tolerance after sintering requires more grinding, increasing processing cost
- Chemical attack from acids, alkalis, or sea water reduces the life of non-carbide materials
- Lack of consistent quality in outsourced carbide parts leads to inconsistent performance
Who It Is For
- Petrochemical pump manufacturers needing wear-resistant bushings for valves and bearings
- Oilfield equipment makers specifying long-life parts for downhole and surface pumps
- Maintenance teams replacing worn shaft sleeves in pumps and valves
- Machinery manufacturers integrating carbide wear parts into new designs
- Distributors sourcing repeatable, high-performance carbide components
Application Scenarios
- Valve rod bushing in submersible oil pumps handling sand-laden crude
- Shaft sleeve in slurry pumps where abrasive solids cause rapid wear
- Bearing bush in centrifugal pumps exposed to sea water and corrosive fluids
- Wear protection in water pumps where metal parts degrade quickly
- Sealing sleeve in high-pressure valves where leakage must be minimized
Technical Features
- Pressed on an imported press for consistent green density
- Sintered in an over-pressure sintering furnace to close residual porosity
- Exclusive raw material formula with wear-resistant additives for extended life
- Regular shape with small tolerance margin on boundary dimensions
- Complete mold inventory allows fast production even without stock
Materials and Grades
- WC-Co cemented carbide with cobalt content selected for hardness and toughness balance
- Lower cobalt grades such as YG6 for maximum wear resistance in clean abrasive service
- Higher cobalt grades such as YG15 for better impact resistance in high-pressure cycling service
Customisation Options
- Manufactured to customer drawings including non-standard and specially shaped parts
- Grade selected based on fluid, abrasion level, and pressure cycle
- Matched bush and shaft sleeve pairs supplied together
- Samples produced for pre-testing before bulk release

Packing and shipping
Quality Control
- Physical properties, shape and tolerance are checked before shipping
- Every order is tested before bulk production is released
- Inspection photographs of the finished order are sent for confirmation before delivery
Use Guide
- Send the drawing with the fluid, solids content, temperature, and pressure cycle so the grade can be matched
- Order the bush and mating shaft sleeve together to ensure proper fit and wear performance
- Ensure full contact between the bush and the housing; avoid point loading on unsupported edges
- Do not expose a cold carbide part to hot fluid; allow thermal equalisation before operation
- Keep one sample from the first batch for comparison when measuring future orders
How It Compares With The Alternatives
| Alternative | Trade-off |
|---|---|
| Hardened steel bush | Steel is cheaper and easier to machine, but wears out quickly in abrasive or corrosive environments, leading to higher downtime and replacement cost |
| Bronze bush | Bronze has lower wear resistance than carbide and is prone to corrosion in oil and water-based fluids, shortening service life |
| Ceramic bush | Ceramic has high hardness and chemical resistance but is brittle under impact; carbide better withstands pressure shock and mechanical stress |
Customized Tungsten Carbide Wear Parts FAQ
Are you a trade company or a manufacturer?
A manufacturer. The company has produced tungsten carbide parts for over 15 years and takes on design and processing of carbide products with technical support.
Where is your factory located?
Zhuzhou City, Hunan Province, China, which is the country's tungsten carbide production base.
Can I get a sample before placing a bulk order?
Yes. Samples are available for pre-testing. Send the drawing and service conditions and a sample can be quoted.
Can you produce the products according to my own drawing?
Yes. OEM and ODM to customer drawings is standard, including non-standard and specially shaped parts.
How long does an order take?
Stock items are shipped 3-5 days after payment is received. Customised items are given a delivery time in the quotation.
How do I know the parts were checked before they shipped?
Physical properties, shape and tolerance are inspected before shipping, and detailed inspection photographs of the order are sent for confirmation before delivery.
Which grade should I choose?
It depends on the fluid and the load. Lower cobalt grades such as YG6 give the best wear resistance in clean abrasive service; higher cobalt grades such as YG15 tolerate impact and pressure shock better. Send the operating conditions and a grade will be recommended.
