Product Description
The Bobcat 331 325 mini excavator track roller is a key undercarriage component located along the lower frame of the machine. Its main function is to carry the weight of the excavator while guiding the track during travel. A worn or damaged bottom roller can cause track misalignment, vibration, abnormal wear, and reduced travel stability.
This replacement roller is built for compact excavators working in construction, landscaping, utility installation, agriculture, and rental fleet applications. It is suitable for repair shops, equipment owners, distributors, and maintenance teams that need dependable mini excavator undercarriage parts.
SQ focuses on practical fitment, stable performance, and consistent supply for aftermarket replacement needs. Before shipment, rollers can be checked for appearance, dimensions, sealing condition, and rotation performance to support reliable installation.

FAQ
How do I confirm if this track roller fits my Bobcat 331 or 325?
Please provide your machine model, serial number, old roller photos, and any visible part number. If possible, also provide the roller width, shaft size, mounting dimensions, and overall diameter.
Can this roller be used for rubber track undercarriage?
Yes, it can be supplied for rubber track applications if the dimensions match your machine. Some machines may have different roller versions, so confirmation is recommended before ordering.
Do you support bulk orders for distributors?
Yes. SQ supports bulk orders, private label requirements, and export packing for undercarriage parts distributors and repair companies.
What should I check before replacing bottom rollers?
Check all rollers on both sides of the undercarriage, track tension, sprocket wear, idler condition, and the track chain or rubber track condition. Replacing only one worn part may not solve the full undercarriage problem.
