Excavator Track Roller Double Flange 2083000570 for Komatsu PC500

Key Features and Benefits

• Premium Forged Alloy Steel: High tensile strength material ensures outstanding resistance to impact, abrasion, and deformation in harsh environments.
• Advanced Heat Treatment: Deep induction hardening on wear surfaces (HRC 48-58, depth 10-12mm) greatly improves hardness and toughness, preventing cracking and extending service life.
• Double Flange Design: Provides enhanced side-to-side track control, reducing derailment risk and improving stability on slopes, turns, and uneven ground.
• Multi-Stage Sealing System: Lifetime lubricated heavy-duty bearings with floating seals protect against dust, mud, and water ingress.
• Precision Machining: Tight tolerances for smooth rotation, minimal vibration, and perfect fit with the track chain.
• Strict Quality Control: Every roller passes ultrasonic flaw detection, hardness testing, dimensional inspection, and load simulation.
• Ready Stock & Fast Shipping: Ample inventory for quick global delivery and reduced machine downtime.

Frequently Asked Questions (FAQ)

Q: How can I confirm this is the correct roller?

A: You can provide any of the following:

• OEM Part Number
• Machine Model
• Machine Serial Number
• Old Roller Photos
• Dimensions

Our engineers will help verify compatibility.

Q: How often should track rollers be inspected?

A: For machines operating in mining or harsh environments, inspect every 500–1,000 operating hours. Check for oil leakage, excessive wear, abnormal noise, and flange damage.

Q: Why does the PC500 use both single flange and double flange rollers? A: Double flange rollers (like 208-30-00570) are used at the ends for stronger lateral guidance and anti-derailment protection. Single flange rollers are used in the middle positions where less side control is needed. They are not interchangeable due to frame design differences.

Q: How do I know if I need the double flange version? A: Check the current rollers on your machine or refer to the parts manual. Double flange rollers are generally installed closest to the idler and sprocket. Send us your serial number for confirmation.

Q: How does your induction quenching process improve the roller's service life?

A: Unlike generic rollers, our induction hardening process targets the specific load-bearing surface to reach HRC 52-58 hardness. This maintains a tough, resilient core to absorb heavy impacts while creating a highly wear-resistant surface that withstands the abrasive conditions of mining job sites.

Q: How do you prevent oil leakage in these rollers?

A: We use premium bi-metallic floating seals that are pressure-tested. These seals are designed to keep lubricants in and contaminants (like mining dust and mud) out, directly addressing the leading cause of premature track roller failure.

Q: Can you provide custom manufacturing for specific mining environments?

A: Absolutely. As a direct manufacturer, we offer custom-engineered solutions. If you operate in extreme abrasive or high-temperature conditions, we can adjust the material composition or heat treatment depth to optimize performance for your specific fleet duty cycle.
