Product Description
32Kg OEM Customization Excavator Track Roller
Product Overview
Model EX100 Track Roller is an undercarriage support roller designed for crawler machinery, compatible with 20-30t class crawler excavators and bulldozers (e.g., Komatsu PC200, Caterpillar D6).
Primary Functions:
- Distributes machine weight to reduce ground pressure
- Guides track chain movement, minimizing friction and wear
- Enhances travel stability and prevents track derailment

Materials & Manufacturing
- Wheel Body: Forged 42CrMo alloy steel, tempered (HRC50-55), with induction-hardened rim (3-5mm depth, HRC58-62)
- Bushing/Bearing: High-strength bronze bushing (CuZn25Al6) with self-lubricating grooves or tapered roller bearings (NTN/SKF, ≥80% grease-filled)
- Seals: Dual-lipped floating oil seals (NBR rubber + alloy steel ring), IP68-rated against dust/water ingress
- Lubrication: Standard 1/8" NPT grease fitting (NLGI Grade 2 lithium grease recommended)
Design Features
- Reinforced thickness (≥25mm per side), optional tungsten carbide overlay (HRC60+)
- Internal direct oil passage for even grease distribution
- Phosphating + anti-rust oil coating (electro-galvanizing available on request)
Performance & Durability
- Service Life: ≥6,000 hours (normal conditions), ≥4,000 hours (harsh conditions)
- Wear Resistance: Rim wear rate ≤0.1mm/100 hours (SAE J1995 standard)
- Seal Integrity: No leakage after 500 hours in muddy/water-submerged environments
Installation & Maintenance
- Torque Requirements: Mounting bolts: 240±10 N*m (thread locker recommended)
- Lubrication Interval: Every 250 hours (heavy-duty), every 500 hours (normal-duty)
- Replacement Criteria: Rim thickness ≤18mm, axial play >2mm, grease leakage >5g/24h
Applications & Compatibility
Recommended for earthmoving, quarrying, and wetland operations. Compatible with 500-600mm width, 2- or 3-grouser track shoes. Interchangeable with equivalent rollers from Shantui, XCMG, etc.
Specifications are based on industry standards. For OEM customization (e.g., material hardness adjustments), provide detailed operational requirements. Always refer to the manufacturer's technical drawing (Part No. EX100-XXXX) for exact tolerances.
