Shengan Track Roller FAQ

Q: What is the primary difference between single-flange and double-flange track rollers?

A: Single-flange track rollers are usually installed near the ends of the track frame (close to the sprocket and front idler), while double-flange rollers are placed along the middle section to maintain strict track chain alignment. Utilizing the correct ratio of single and double-flange rollers prevents track derailment and uneven rail wear.

Q: How do I know when it is time to replace an excavator bottom roller?

A: Inspect your undercarriage every 500 operating hours. Key indicators for replacement include oil leaks around the seals, flat spots on the roller tread, severe flange wear, or squeaking and grinding noises during travel.

Q: Do you provide bulk wholesale discounts and OEM private label manufacturing?

A: Yes. SA Excavator Parts supports regional machinery parts distributors, repair facilities, and fleet owners with direct factory pricing, low MOQs, and custom branding/packaging options.
