1. Preparation - Cleaning
Use LOCTITE® 7200 for easier removal of residues in case of old retaining adhesive. It is recommended to use LOCTITE® 7063 to degrease and clean surfaces prior to applying the adhesive. For gaps larger than 0.5mm or worn out shafts, bearing seats or keyways, use LOCTITE® metal-filled compounds.
2. Preparation - Activation
If cure speed is too slow due to passive metals or low temperature (below 5°C), use activator LOCTITE® 7240 or LOCTITE® 7649 (see cure speed vs activator graph in the TDS).
3. Application - For Slip Fitted Assemblies
Apply adhesive around the leading edge of the male component and the inside of the female component and use a rotating motion during assembly to ensure good coverage.
4. Application - For Press Fitted Assemblies
Apply adhesive thoroughly to both bond surfaces and assemble at high press on rates.
5. Application - For Shrink Fitted Assemblies
Apply the adhesive onto the shaft; heat the collar to create enough clearance for free assembly.
6. Equipment
For manual assembly of adhesive, the use of a peristaltic hand pump is recommended to ensure a consistent application volume. For semi-automatic or fully-automated dispensing options, contact our technical service team for advice.
7. Disassembly
Apply localised heat to approximately 250°C; disassemble while hot. For corroded or seized parts, use LOCTITE® LB 8040 Freeze and Release.

The low viscosity of LOCTITE® 603 makes it ideal for augmenting press/interference fits, or slip-fitted assemblies with small clearances. The high-strength adhesive reliably prevents loosening from shock and vibration on cylindrical parts, such as roller bearings or oil-impregnated bushings mounted in housings, while it also prevents corrosion between the metal parts.
