Galbreath 521AO Roller Replacement
The Galbreath 521AO side roller is an important wear component on compatible roll-off equipment. Rollers are subjected to repeated contact, rotation, impact, and container movement during normal operation.
When a roller becomes worn or the bushing begins to fail, replacing it can help maintain proper container movement and reduce wear on surrounding components.
This AT388 replacement roller provides the same key dimensions as the Galbreath 521AO application:
4" OD × 2" ID × 3" wide
The bronze-bushed design includes grease grooves to allow for regular lubrication and help extend roller service life.

Fits Compatible Galbreath Roll-Off Equipment
The AT388 is listed as a replacement for the Galbreath 521AO and is also referenced for the Galbreath 386AO application.
Because roller configurations can vary by equipment model and position, always verify the outside diameter, inside diameter, width, shaft/pin configuration, and mounting location before purchasing.
For fitment assistance, provide your equipment manufacturer, model number, and roller position.
Why Replace a Worn Side Roller?
A worn roll-off roller can cause more than just noise or vibration. Excessive roller wear can contribute to container alignment problems, increased cable wear, and damage to the roller bed.
Replacing a worn roller before the bushing fails completely can help prevent additional wear to the equipment. BENLEE's roller collection specifically recommends replacing rollers before the bushing wears into the roller body.
