Kubota U55 Lower Track Roller

Aftermarket OEM Replacement – Part #RD411-21700

Improve undercarriage performance and reliability with this aftermarket lower track roller for the Kubota U55 from United Skid Tracks. Bottom rollers support the weight of the machine while guiding the track during travel and digging, making them a critical wear component.

This bottom roller is designed to fit the newer Kubota U55 models and features an all-new sealed ball-bearing design for smooth operation and long-term durability. A stainless steel shaft provides added strength and corrosion resistance for extended service life.

For best results, it is recommended to replace all bottom rollers on one side of the machine at the same time. Installing a new roller next to worn rollers can create uneven load distribution and reduce the lifespan of the new component.

These rollers arrive fully assembled and are ready for installation. Original factory mounting bolts can be reused for a quick and straightforward install.

This is a dual-flange, outside guide-style bottom roller manufactured to original specifications. High-quality double-lip seals help keep dirt and debris out while retaining lubrication for long-lasting performance. These rollers are direct-fit replacements designed for use with the original Kubota rubber track guide system and provide a guaranteed fit.

Important Fitment Note:
