Product Description
Direct-Fit QUY130 Undercarriage Carrier Roller
The Fuwa QUY130 top roller — also called a carrier roller — sits above the track frame and keeps the upper run of the track chain lifted off the ground between the sprocket and idler. Without it, the chain sags, slaps the frame on every travel move, and wears out the link pins faster than anything else on the undercarriage.
This aftermarket unit matches the original QUY130 undercarriage carrier roller — it drops straight in, no modification, no shimming, no guesswork. If you're sourcing by machine serial number or pulling a worn roller to measure, send us a photo and we'll confirm the fit before anything ships.

Frequently Asked Questions
Does this top roller fit the Fuwa QUY130 directly?
Yes. This carrier roller is built to the original QUY130 undercarriage spec. It drops straight in with no modification or shimming required. If you want to verify by serial number first, send us a photo of the worn roller and we'll confirm before anything ships.
What steel grade is used in this carrier roller?
The roller shell and shaft are made from 50Mn high-strength manganese steel, CNC-turned and ground to tolerance. The surface receives anti-rust paint treatment before packing.
How long does the sealed lubrication last?
Under normal operating conditions on a QUY130, the sealed lubrication system typically runs 300 to 500 operating hours before the floating seal shows wear. Replacing the roller at first sign of seal failure prevents grit contamination and protects the track chain.
Can I order a custom size or branded roller?
Yes. We offer customization on flange width, bore diameter, paint color and brand identity. Contact us with your drawings or a sample roller for a quote.
