Bearing Bush / Bogie Bracket – PU-BU
It helps absorb vibration and impact loads while maintaining proper alignment of the bogie bracket. The combination of PU (polyurethane) and BU (rubber) materials provides optimal flexibility, strength, and wear resistance compared to standard bushings. This hybrid construction prevents metal-to-metal contact, reduces noise, and protects adjoining suspension components from stress. It ensures stable and reliable performance under heavy-duty load cycles.
Engineered for demanding commercial applications, this bearing bush improves vehicle stability and handling by minimizing play within the bracket. Its durable material composition resists deformation, cracking, and fatigue even on rough terrain. By maintaining consistent alignment and cushioning, it extends suspension lifespan and reduces maintenance needs. Ideal for trucks exposed to continuous load variations and harsh road conditions.
Key Features
- PU-BU hybrid material for superior strength and flexibility
- Reduces vibration, noise, and suspension stress
- Maintains proper alignment inside the bogie bracket
- Prevents metal-to-metal contact for extended component life
- High resistance to wear, deformation, and fatigue

FAQ
Why use a PU-BU bush instead of a normal rubber bush?
PU-BU provides better durability, improved load handling, and longer service life under heavy-duty operations.
What are signs of a worn bogie bush?
Excessive vibration, knocking sounds, misalignment, or irregular suspension movement.
