U27-4 TOP ROLLER (KU-RG24821900)
Description:
The U27-4 TOP ROLLER (KU-RG24821900) supports the upper track chain as it travels over the undercarriage, while also maintaining correct track alignment and tension. It sits above the track frame and guides the track during operation, so it prevents excessive wear and ensures smooth movement.
Kubota engineers this component for durability; therefore, it withstands continuous load, shock, and harsh working environments. In addition, it features sealed bearings and hardened surfaces, which reduce friction and extend service life. As a result, it plays a critical role in maintaining undercarriage performance and machine stability.
