The Oil Film Lock: Securing Camshaft Bushings Against Spin-Out

  • Post last modified:October 9, 2025

The retention of camshaft bushings is a critical, High Strength engine application. These bushings are subject to: immense rotational friction and load, continuous exposure to hot engine oil, and high engine operating temperatures. Failure (bushings spinning or walking out) results in immediate oil pressure loss, camshaft seizure, and catastrophic engine failure.

The optimal solution is a high-strength retaining compound engineered specifically for dynamic loads and superior thermal and oil resistance.

INCURE WeldLock™ 347 Retaining Compound (Green)

The INCURE WeldLock™ 347 Retaining Compound is the definitive choice for securing camshaft bushings, as it is a high-strength solution designed for dynamic loads and superior thermal stability in motor components.

Key FeaturePerformance for Camshaft Bushings
High Strength, Fast CuringCreates a monolithic bond that resists the extreme rotational torque and friction exerted on the bushing, preventing spin-out.
Temperature Resistance (175∘C)Maintains full structural integrity under the sustained, elevated temperatures of the engine block and cylinder head, crucial for long-term reliability.
Ideal Gap Fill (Up to 0.15mm)Perfectly secures standard, close-tolerance press-fit bushings, eliminating the micromovement (fretting) that destroys the interface and compromises oil pressure.
Core ApplicationSpecifically suited for securing rotors and shafts in motors and mechanical drives, directly matching the demands of the rotating camshaft within the engine.

The WeldLock™ 347 provides the required security and thermal stability for this demanding engine application, ensuring precise camshaft timing and oil pressure.
