Product Overview
This is a tungsten carbide bush or wear part made from cemented carbide. It is pressed on an imported press and sintered in an over-pressure sintering furnace to achieve stable quality, good density and high comprehensive performance. The product is designed for use in high-wear environments where steel or other materials fail quickly. It is available in standard sizes or custom shapes to fit specific applications.
Key Benefits
- Long service life due to exclusive raw material formula with wear-resistant elements
- Stable quality with good density and high comprehensive performance
- Lower processing cost because of small tolerance margin on boundary dimensions
- Fast delivery with complete mould inventory and short production cycle
- Chemically stable against acid, alkali, alcohol, ether, hydrocarbons, oil, detergent, water, and sea water
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 duty |
Problems It Solves
- Steel shaft sleeves wear out quickly in abrasive or corrosive environments, leading to frequent replacements
- Clearance increases between shaft and bush as wear progresses, causing leakage and reduced efficiency
- High grinding allowance on parts from poor pressing or sintering increases processing cost
- Chemical attack from acids, alkalis, or sea water reduces the life of non-carbide parts
- Lack of consistent quality in outsourced wear parts leads to inconsistent performance
Who It Is For
- Petrochemical equipment manufacturers needing wear-resistant bushings for pumps and valves
- Ball mill and bead mill operators replacing worn shaft sleeves and bearing components
- Mould and die shops using carbide bushings in high-wear forming tools
- Woodworking and metal cutting tool makers requiring durable guide or support parts
- Mechanical parts manufacturers sourcing reliable, repeatable wear components
Application Scenarios
- Shaft sleeve in valve rods to reduce leakage and maintain sealing under pressure
- Wear protection in bearings where the shaft and seat experience high friction
- Submersible oil pump components exposed to sand-laden crude and abrasive fluids
- Slurry pump bushings in mineral processing where solids cause rapid wear
- Centrifugal and water pump parts in marine environments with sea water exposure
Technical Features
- Pressed on an imported press for consistent green density
- Sintered in an over-pressure sintering furnace to close residual porosity and stabilise density
- Exclusive raw material formula with wear-resistant elements to extend service life
- Regular geometry with small tolerance margin on boundary dimensions
- Complete range of standard moulds allows fast production even without stock
Materials and Grades
- WC-Co cemented carbide with cobalt content selected for the balance of hardness and toughness
- Lower cobalt grades such as YG6 for maximum wear resistance in clean abrasive service
- Higher cobalt grades such as YG15 where the bush sees impact or pressure shock
- Exclusive raw material formula with wear-resistant additions for extended service life
Customisation Options
- Manufactured to customer drawings including non-standard and specially shaped bushes
- Grade changed to suit the fluid, abrasive load and pressure cycle
- Matched bush and shaft pairs supplied together for proper fit
- 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 operating conditions including fluid, solids content, temperature and pressure cycle so the grade can be matched
- Order the bush and mating shaft together to ensure proper fit and reduce clearance
- Support the bush on a full seat face; avoid point loading on unsupported edges to prevent chipping
- Do not shock a cold carbide part into hot service; allow the assembly to equalise temperature
- Keep one sample from the first batch for comparison when measuring a repeat order
How It Compares With The Alternatives
| Alternative | Trade-off |
|---|---|
| Hardened steel bush | Steel is cheaper per piece and easier to machine, but wears out faster in abrasive or corrosive environments, leading to higher downtime and replacement frequency |
| Ceramic bush | Ceramic matches carbide on chemical resistance but is more brittle under impact; carbide handles pressure shock better in dynamic applications |
| Coated or hardfaced bush | A coating wears through and then the base metal fails quickly; solid carbide wears uniformly through the entire section |
Tungsten Carbide Bush /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 sold for pre-testing. Send the drawing and the 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 for this part, including specially shaped bushes and matched pairs.
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.
