Custom wear pads for excavator buckets are engineered carbide or tungsten carbide plates that protect high‑wear areas of the bucket. They are designed to match the bucket’s geometry and working conditions (abrasive soil, rock, gravel). Unlike standard liners, custom pads are brazed, welded, or bolted on, extending bucket life 5–10× while minimising downtime.

What Are Custom Wear Pads and How Do They Differ from Standard Bucket Liners?
Custom wear pads are tailor‑made protective components, typically made from tungsten carbide, designed for specific bucket dimensions and material types. They offer precise fit, optimized wear distribution, and longer life compared to standard off‑the‑shelf steel liners. Attachment methods include brazing (common for SENTHAI’s JOMA‑style inserts), welding, or bolting, each with trade‑offs in strength and replacement ease.
SENTHAI’s engineers evaluate the bucket’s working environment to recommend the optimal attachment method and insert geometry – a service built on 21+ years of field‑proven design.
How Does Carbide Compare to Other Materials for Bucket Wear Protection?
Tungsten carbide provides 8–10× the wear life of standard AR steel, but its extreme hardness (88–92 HRA) requires careful design to manage impact. SENTHAI’s grain‑size control and vacuum sintering process balance hardness and toughness for buckets handling mixed rock and abrasive soil.
| Material | Hardness (HRC / HRA) | Impact Resistance | Wear Life vs. Standard Steel | Typical Cost Index |
|---|---|---|---|---|
| Standard AR Steel (Hardox 400) | 400 HB (~40 HRC) | High | 1× | 1× |
| Chrome Carbide Overlay (CCO) | 55–62 HRC | Moderate | 3–5× | 2–3× |
| Tungsten Carbide (SENTHAI grade) | 88–92 HRA | Good (proper design) | 8–10× | 4–6× |
Which Factors Should You Consider When Designing Custom Wear Pads?
Key factors include bucket geometry (width, depth, radius, high‑strike zones), material handled (abrasive sand, granite, clay), operating conditions (impact frequency, moisture, temperature), and wear pattern analysis. SENTHAI’s design team provides a free consultation checklist covering bucket dimensions, material type, and operator feedback to create a custom solution.
SENTHAI’s engineers evaluate existing wear history to map pad density and thickness, ensuring maximum protection where it is needed most.
How Does SENTHAI’s Fully Automated Manufacturing Ensure Consistent Quality?
SENTHAI’s in-house production includes five stages: wet grinding, pressing, sintering, welding, and vulcanization – each precisely controlled. Vacuum sintering eliminates porosity for maximum density, and induction brazing produces consistent bond strength between carbide and steel. This is critical for high‑impact bucket applications. The facility is ISO 9001 and ISO 14001 certified, with 21+ years of carbide expertise.
Every batch is fully traceable, and SENTHAI performs rigorous inspections at the end of each production stage.
How Can Custom Carbide Wear Pads Reduce Total Cost of Ownership?
Custom carbide pads reduce downtime with 8–10× longer life, protect the bucket base metal from gouging, and improve fuel efficiency by maintaining original bucket profile. A 30‑ton excavator operating in blasted granite reduced annual wear part costs by 55% and eliminated two mid‑season change‑outs after switching to SENTHAI carbide pads.

Fewer blade changes also mean lower labour costs and less equipment idle time – directly improving profitability.

FAQs
How long do custom carbide wear pads typically last compared to standard steel liners?
In similar abrasive conditions, SENTHAI carbide wear pads deliver 8–10× longer life than standard AR400 steel liners. Actual life depends on material type, impact intensity, and pad design.
Can SENTHAI design wear pads for non‑standard bucket shapes?
Yes. SENTHAI has experience with over 80 global partners covering excavators, wheel loaders, scrapers, and specialized attachments. Submit bucket drawings or photos for a custom design review.
What is the minimum order quantity for custom wear pads?
MOQ depends on pad complexity. For standard carbide inserts similar to JOMA‑style blades, MOQ is typically 500 pieces; for full bucket liners, MOQ may be 10–20 sets. Contact SENTHAI for specific quotes.
Are SENTHAI’s wear pads compatible with existing bolting or welding patterns?
Yes. During the design phase, SENTHAI engineers adapt the pad backing plate to match existing bolt holes, weld dimples, or mounting brackets – minimising bucket modification labour.
Does SENTHAI offer a warranty on custom wear pads?
SENTHAI stands by its full in‑house production and strict quality control (ISO 9001). Warranties are negotiated per contract based on application and expected wear life. Contact the sales team for detailed terms.
