3. Materials & Manufacturing
Wheel Body: Forged 42CrMo alloy steel, tempered (HRC50-55), with induction-hardened rim (3-5mm depth, HRC58-62).
Bushing/Bearing:
Option 1: High-strength bronze bushing (CuZn25Al6) with self-lubricating grooves.
Option 2: 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).
4. Design Features
5. Performance & Durability
Service Life:
Normal conditions (earthwork): ≥6,000 hours.
Harsh conditions (mining/rock): ≥4,000 hours (shorter lubrication intervals required).
Wear Resistance: Rim wear rate ≤0.1mm/100 hours (SAE J1995 standard).
Seal Integrity: No leakage after 500 hours in muddy/water-submerged environments.
6. Installation & Maintenance
Torque Requirements:
Mounting bolts: 240±10 N·m (thread locker recommended).
Grease pressure: ≤500 kPa (to avoid seal damage).
Lubrication Interval:
Heavy-duty: Every 250 hours.
Normal-duty: Every 500 hours (120ml per lubrication).
Replacement Criteria:
Rim thickness ≤18mm.
Axial play >2mm.
Grease leakage >5g/24h due to seal failure.
7. Applications & Compatibility
Recommended Use: Earthmoving, quarrying, wetland operations.
Track Compatibility: 500-600mm width, 2- or 3-grouser track shoes.
Interchangeability: Replaces equivalent rollers from Shantui, XCMG, etc. (verify shaft diameter/bolt pattern).
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.
