Title:
BEARING,NEEDLE (KU-6A61035320)
Description:
The Kubota 6A610-35320 Needle Bearing is a genuine Kubota precision bearing designed to support rotating components within compatible hydrostatic transmission (HST) assemblies. Its needle-bearing design reduces friction between moving components, helping the transmission operate smoothly and efficiently.
During operation, the bearing supports rotating shafts and manages radial loads within the HST assembly. Consequently, excessive wear or bearing damage can increase friction, create abnormal noise and affect transmission performance. Replacing the bearing with the correct OEM component helps restore smooth movement and reliable power transmission.
Furthermore, Kubota parts diagrams place 6A610-35320 within HST port-block cover, motor-shaft and valve assemblies. The component appears across a wide range of B Series tractors, BX Series compact tractors, RTV utility vehicles and ZD/ZG mower applications.
