Dingtai manufactures Samsung track rollers, the primary load-bearing components that support excavator weight and guide track shoes through the undercarriage system.
We are a factory-direct China manufacturer offering complete OEM manufacturing services for global distributors, rental fleets, and equipment owners.
Our rollers resist deformation, seal failure, and premature wear, helping prevent track derailment and costly downtime on demanding job sites.
With over 20 years of experience, Dingtai maintains ISO9001 and SGS certified quality systems for consistent, traceable undercarriage component production.
Each Samsung track roller is forged from 35MnB steel, deep quenched, and precision machined for long service life under extreme load.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB steel gives high tensile strength, impact resistance, and structural integrity under heavy tracked machinery loads.
- Deep Quenching/Heat Treatment: Induction hardening creates a deep wear-resistant surface while maintaining a tough core, reducing cracking and extending roller life.
- 100% QC Inspection: Every batch undergoes dimensional, hardness, and seal leakage testing, ensuring zero-defect delivery for replacement and OEM production requirements.
- OEM Capabilities: We manufacture to sample or drawing, matching original Samsung dimensions and fitment for seamless integration with existing track frames.
Our catalog of Samsung Track Rollers includes various specifications, fully compatible with Samsung SE and MX series excavators and bulldozers.

Technical Features
Floating seal design retains lubricant and blocks abrasive dirt, maintaining a constant oil film that prevents metal-to-metal contact.
Bimetal bushings distribute radial loads evenly across the shaft, reducing localized stress and extending service intervals in heavy-duty cycles.
Deep quenching produces a hardened case of 8–12 mm, giving high wear resistance without sacrificing core toughness under impact.
Applications
- Mining and quarrying: heavy excavation and haul road equipment.
- Road construction: grading, trenching, and asphalt milling support.
- Demolition: high-impact tracked machinery in unstable ground.
- Heavy civil projects: dams, bridges, and pipeline work.
- Forestry and land clearing: abrasive debris and rough terrain.
Frequently Asked Questions
Q: What is the minimum order quantity for Samsung track rollers?
MOQ is usually 4–8 pieces per model. We also support trial sample orders for new customers.
Q: What is the delivery time?
Standard production takes 15–30 days after order confirmation. Stock rollers can ship within 7 days.
Q: What heat treatment depth do your rollers have?
Surface induction hardening depth is typically 8–12 mm, reaching HRC 52–58 for extended wear life.
Q: What is your warranty policy?
We offer 12 months or 2,000 working hours warranty against manufacturing defects under normal operating conditions.
Q: Can you match a Samsung OEM part number?
Yes. Provide the OEM part number or drawing, and we cross-reference and manufacture to exact specifications.
Q: Do these rollers fit Volvo CE machines from Samsung-era production?
Many Samsung models transitioned to Volvo CE. We supply compatible rollers based on part number and undercarriage verification.
Q: How are rollers inspected before shipment?
Each batch receives dimensional checks, hardness testing, and seal leak testing to ensure zero-defect delivery.
Maintenance Guide
- Inspection: Check tread wear, flange damage, shaft play, and oil leaks every 250 working hours.
- Installation: Use calibrated torque tools and follow OEM tightening sequences to prevent uneven roller loading.
- Lubrication: Never mix oil grades; maintain sealed lubricant level to preserve floating seal performance.
- Replacement: Replace rollers when tread depth is worn beyond OEM limits or when oil contamination appears.
