Securing components (like bearings or drive sprockets) onto conveyor roller shafts is essential for smooth and reliable material handling systems. This joint is subjected to heavy radial loads (from the conveyed material), continuous rotational fatigue, constant vibration, and often exposure to dust, moisture, and temperature fluctuations.Maintaining a zero-clearance, non-shifting fit is vital to prevent bearing walk, premature failure, and the costly downtime associated with roller replacement.
INCURE WeldLock™ 365 Retaining Compound
For securing components onto the roller shaft—especially bearing races or drive hubs—where maximum shear strengthand resistance to vibration/fatigue are paramount, the WeldLock™ 365 provides the highest structural integrity. Its superior strength ensures components cannot shift, preserving the bearing fit and concentricity required for long-term operation.
| Feature & Benefit | Technical Insight for Conveyor Roller Shafts | Conversion Value |
| Highest Strength (365) | Cures to an extremely high-shear strength, rigid plastic, providing maximum resistance to radial load and torsional slip. | Zero Slippage: Guarantees absolute 100%torque transmission (if driven) and prevents fretting corrosion. |
| High Temperature Resistance | Withstands continuous operational temperatures up to 200∘C (392∘F), essential for systems operating in warmer environments. | End the Heat Threat: Ensures the bond remains strong and rigid under maximum thermal load. |
| Fills Close Clearance Gaps | Ideal for components with an interference or true close-tolerance slip fit (less than 0.05 mm diametral clearance). | Maximizes Concentricity: Converts the fit into an integrated component, optimizing roller balance and stability. |
| Fluid/Contaminant Immunity | Inert to common grease, oil, and environmental contaminants, ensuring the integrity of the joint is protected. | Reliability Assured: The bond remains permanently intact despite constant exposure. |
Application Steps: Locking Roller Shaft Components for Maximum Service Life
Preparation (Critical): Thoroughly clean both the component bore (bearing inner race, hub bore) and the roller shaft surface. Remove all oil, grease, rust, and residue. Use a powerful degreasing solvent (like acetone or industrial cleaner) and wipe until both metal surfaces are perfectly dry.
Application: Apply a continuous, liberal bead of WeldLock™ 365 evenly around the shaft surface. Alternatively, apply it to the inside circumference of the component bore. Ensure the compound completely covers the mating area.
Assembly: Press or slide the component onto the shaft. Ensure the component is seated correctly (axially) and wipe away any excess compound immediately.
Curing Time (Mandatory): Allow a full 24 hours for the compound to reach full cure strength before installing the roller or operating the conveyor system under load.
Alternative Consideration (Worn or Large Gaps): If the bore-to-shaft clearance is larger (up to 0.25 mm), use INCURE WeldLock™ 356 (Metallic Grey). This compound is formulated with metallic fillers to tolerate larger diametrical clearances while still providing high structural integrity.
Stop risking bearing walk and ensure your conveyor roller shafts provide smooth, reliable operation.
