Dingtai manufactures JCB track rollers, the bottom roller components that support excavator undercarriage weight and guide track chain movement.
We operate factory-direct, providing complete OEM manufacturing services for global equipment owners, dealers, parts distributors, and rental fleets.
Our rollers resist premature wear and flange cracking, reducing unplanned downtime on demanding job sites and heavy load conditions.
With over 20 years of experience and ISO9001/SGS certified production, Dingtai delivers consistent quality and traceable batch inspection.
Each JCB track roller uses 35MnB steel and deep quenching heat treatment to achieve high hardness and extended service life.
Core Selling Points
- Premium 35MnB Material: Forged from high-strength 35MnB steel to provide excellent impact resistance and load-bearing capacity under severe undercarriage stress.
- Deep Quenching/Heat Treatment: Advanced induction hardening produces a deep hardened layer that resists wear, spalling, and fatigue cracking.
- Global Brand Compatibility: Manufactured to match JCB OEM dimensions and bolt patterns, ensuring direct replacement without modification.
- 100% QC Inspection: Every roller passes dimensional checks, hardness testing, and seal pressure verification before shipment to ensure traceable quality.
Our catalog of JCB Track Roller includes various specifications, fully compatible with JCB excavators and bulldozers.

Delivery & Logistics
Dingtai provides factory-direct pricing, reliable export packaging, flexible MOQ from one pallet, and delivery within 15–30 days after order confirmation.
Technical Features
The roller assembly uses a double-cone floating seal that maintains a permanent oil film and blocks dirt, water, and abrasive particles.
A high-strength bimetal bushing with graphite inserts enhances rotation smoothness and prevents metal-to-metal contact under shock loads.
Deep induction quenching creates a 5–9 mm hardened case on the tread surface, preserving core toughness for impact resistance.
Applications
- Mining and quarrying: continuous rock loading, abrasive ground.
- Road construction: grading and trenching on compacted soil.
- Demolition and urban excavation: high cycle work on mixed surfaces.
- Forestry and land clearing: wet, muddy, uneven terrain.
- Heavy civil infrastructure: bridge, pipeline, and dam projects.

Maintenance Guide
- Clean the mounting surface and inspect bolt holes for elongation or damage before installing new rollers.
- Torque bolts to JCB specified values and re-check after the first 50 working hours.
- Check oil leakage or excessive play during routine track inspection; replace rollers showing flange wear or seizure.
- Rotate or replace track rollers when tread wear exceeds 25% of original diameter to protect the full undercarriage.
