John Deere 50D Bottom Roller Assembly

Aftermarket OEM Replacement – Part #9239528

Keep your undercarriage performing reliably with this aftermarket bottom roller assembly for the John Deere 50D mini excavator. Bottom rollers support the weight of the machine during travel and digging while guiding the track for smooth, consistent operation.

There are significant differences between rollers used on other John Deere 50 series mini excavators. Please verify your exact model before ordering to ensure proper fit and performance.

This is a single-flange bottom roller manufactured to original specifications and built for long service life. It features high-quality double-lip seals designed to keep dirt and debris out while retaining lubrication under demanding operating conditions.

The flange rides in the center of the track guide to help prevent de-tracking, while the machine’s weight is carried on the outer surface of the roller. Replacing worn bottom rollers helps reduce uneven wear and extend the life of your tracks and undercarriage components.

United Skid Tracks offers a full range of undercarriage parts, including bottom rollers, rubber tracks, and sprockets, to keep your John Deere 50D working efficiently on the jobsite.
