DH508 Track Roller for Nippon Sharyo Crawler Crane
The DH508 track roller is a lower roller used in the undercarriage of Nippon Sharyo crawler cranes. It rests on the track chain, carries the machine load and helps the crane travel smoothly during lifting, foundation work and jobsite movement.
Buyers sourcing Japan crane bottom rollers typically require accurate model matching, consistent quality, clear lead time and safe export packing. ShunQi Track helps customers identify the correct part by machine model, old part photos, measurements or OEM reference number.

This lower roller is designed to carry track chain load, reduce unstable movement and support smooth travel during crane operation. A correctly matched part helps protect related components including track shoes, idlers, top rollers and sprockets.
Why the Correct Track Roller Matters
A wrong or low-quality roller causes difficult installation, uneven wear, track chain damage and repeated downtime. For international buyers, receiving an incorrect part often costs more than the price difference between two suppliers.
For distributors: accurate model information reduces wrong-part claims and improves repeat-order efficiency.
For rental fleet owners: reliable replacement parts keep crawler cranes ready for the next project schedule.
For repair workshops: correct dimensions and fitment confirmation help avoid installation delays.
For overseas buyers: suitable export packing and trade terms reduce transport risk and purchasing uncertainty.

Track Roller Maintenance Guide
Track rollers work under continuous pressure and ground impact. Regular inspection prevents early failure and protects the whole undercarriage system. Planned inspection also reduces emergency repair costs for rental fleets and workshops.

Check whether the roller rotates smoothly and without abnormal noise.
Inspect for oil leakage, cracks, serious side wear or uneven surface wear.
Remove mud, stones and concrete residue after jobsite operation.
Replace damaged rollers early to avoid extra stress on track chains and sprockets.
For rental fleets, record replacement intervals to plan spare parts inventory more accurately.
How to Confirm the Correct DH508 Track Roller
To confirm the correct part, send the crawler crane model, old roller photos, installation position, diameter, width, shaft size and required quantity. If you have an OEM number or a parts manual page, confirmation will be faster.
For urgent orders, also provide your destination country, expected delivery time and preferred shipping method. We will check availability, lead time and packing options before quotation.
Frequently Asked Questions
How do I choose the right crane track roller?
Start with the crane brand, model, undercarriage position and old roller dimensions. For a Nippon Sharyo DH508 crane, useful details include old part photos, roller diameter, roller width, shaft or mounting size, and the quantity needed. Confirm repeatable quality with the supplier, check stock and lead time, and verify fitment before scheduling installation.
When should a crawler crane bottom roller be replaced?
Replace the roller when it shows oil leakage, abnormal noise, poor rotation, cracked housing, serious side wear or uneven surface wear. If the track chain does not run smoothly or the crane shows unstable travel, inspect the rollers together with idlers, sprockets and track shoes.
