Sleeves in heavy-duty drills (e.g., impact drivers, large hammer drills) require a secure bond to resist high torque and impact vibration. However, these tools are often disassembled for maintenance, repair, or component replacement. This demands a retaining compound that is secure yet allows for easier, non-destructive disassembly.
This is a Medium Strength, Serviceable application.
INCURE WeldLock™ 338 Retaining Compound (Yellow)
The INCURE WeldLock™ 338 Retaining Compound is the ideal functional “Medium Strength” solution. It’s designed for assemblies where future disassembly is required, providing enough holding power to transmit torque and resist vibration without making sleeve removal a destructive process.
| Key Feature | Performance for Drill Sleeves |
| Serviceable Bond (Yellow) | Designed for assemblies requiring removal or repositioning. Locks the sleeve securely but allows for easier, non-destructive separation for tool maintenance. |
| Excellent Vibration Resistance | Provides reliable holding power against continuous high-speed rotation and operational shock/impact, preventing the sleeve from shifting. |
| Gap Fill (Up to 0.25mm) | Effectively fills the annular space, ensuring a solid, unified interface between the sleeve and the housing/bore. |
| Temperature Resistance (150∘C) | Maintains integrity under the sustained operational temperatures of power tool motors and gearboxes. |
Application Steps: Installing Sleeves in Heavy-Duty Drills
For optimal retention and reliable, yet removable, installation of sleeves, follow these steps:
1. Surface Preparation (The Foundation)
- Clean: Thoroughly clean both the sleeve’s outer surface and the housing/bore. Surfaces must be absolutely free of all grease, oil, and contaminants. Use an industrial cleaner (e.g., acetone) and wipe dry.
- Activate (If Needed): If the ambient temperature is low, applying a chemical activator can ensure faster, more consistent curing.
2. Product Application
- Apply: Apply a continuous, thin bead of WeldLock™ 338 around the full circumference of either the outer surface of the sleeve or the internal bore of the housing.
- Ensure Coverage: Ensure the adhesive completely wets the entire mating surface as the sleeve is inserted.
3. Assembly and Curing
- Assemble: Immediately slide or press the sleeve into the housing bore. Ensure the components are aligned correctly before the compound fixtures.
- Wipe Excess: Remove any excess adhesive visible outside the joint immediately after assembly.
- Cure: Allow the assembly to fixture before handling (typically 10-30 minutes). Allow a full 24 hours for the compound to reach maximum strength before placing the drill back into service.
