1ONA supplies high‑quality bronze countershaft bushings specifically engineered for reliable power transmission and long service life. Each crusher requires two bushings – one installed at each end inside the countershaft box. These bushings serve as the interface between the rotating countershaft and the stationary box, preventing direct metal‑to‑metal contact.

Key Features
Made from premium bronze alloy, ONA countershaft bushings provide five essential benefits:
1. Friction reduction: The self‑lubricating bronze surface significantly lowers friction between the shaft and housing, reducing wear and extending component life.
2. Shaft support & protection: They securely support the countershaft, preventing vibration or displacement under heavy loads, and cushion shock loads to protect adjacent precision parts.
3. Heat dissipation: Bronze’s excellent thermal conductivity helps dissipate heat generated during high‑speed rotation, preventing overheating and maintaining stable performance.
4. Motion accuracy: The smooth, precision‑machined surface ensures accurate tracking of the shaft’s rotational path, avoiding misalignment or uneven wear.
5. Equipment longevity: By absorbing normal wear, the bushing sacrifices itself to protect the much more expensive countershaft and box.
Installation & Maintenance
Each countershaft bushing is mounted inside the countershaft box – one at the drive end, one at the opposite end. Proper lubrication is essential; ONA bushings feature optimized oil grooves for consistent film distribution. Regular inspection of clearance and wear patterns helps schedule timely replacement, preventing damage to the housing or shaft. All ONA countershaft bushings are cast from high‑grade copper alloy, machined to OEM tolerances, and 100% dimensionally inspected. Custom sizes are available upon request.
