Title:
THRUST,COLLAR (KU-RD41166340)
Description:
The Genuine Kubota THRUST, COLLAR (Part No. RD411-66340 / KU-RD41166340) is an OEM thrust collar designed for compatible Kubota mini excavators. This precision-machined component supports rotating and pivoting assemblies by providing controlled spacing, reducing friction, and maintaining correct alignment between mating parts.
Manufactured to Kubota’s original equipment specifications, this genuine replacement thrust collar provides the correct dimensions, material quality, and fit required for reliable operation. It is used within swing bracket and linkage assemblies where accurate positioning and load distribution are essential for smooth machine movement.
A worn or damaged thrust collar can contribute to excessive play, misalignment, increased friction, and accelerated wear of surrounding components. Replacing the collar with a genuine Kubota part helps restore proper clearances and maintain the original performance of the machine assembly.
