Title:
Kubota BUSHING(KNUCKLE CASE) (KU-K759117860)
Description:
The Kubota K7591-17860 knuckle case bushing supports and stabilises the steering knuckle assembly, thereby ensuring smooth steering movement and reducing wear. In operation, it acts as a bearing surface between moving metal components inside the knuckle case. First, the bushing fits inside the knuckle housing, where the steering shaft or pivot rotates. By doing so, it provides a low-friction surface that allows controlled movement. Next, the bushing absorbs loads generated during steering and driving. As a result, it prevents direct metal-to-metal contact and reduces component wear. In addition, it maintains correct alignment of the steering assembly. Therefore, it helps ensure stable handling and consistent wheel positioning. Moreover, the bushing protects internal components from damage caused by vibration, shock loads, and contamination. This ensures long-term reliability in demanding working conditions.
Construction & Design
Kubota engineers design this bushing for durability and precision:
- Cylindrical sleeve design:
Fits tightly into the knuckle case housing
- Wear-resistant material (metal-backed or composite):
Provides long service life under load
- Smooth internal surface:
Allows efficient rotation of the shaft or pivot
- Precision sizing:
Ensures correct fit and alignment within the steering system
- Corrosion-resistant finish:
Protects against moisture, dirt, and harsh environments
