LOCTITE® 609 is designed for the bonding of cylindrical fitting parts. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Typical applications include rotor to shafts in fractional and subfractional horsepower motors. Locks bushings and sleeves in housings on shafts. Augments press fits.
FEATURES AND BENEFITS
- Prevents loosening: It fills all gaps between the cylindrical components and cures into a hard thermoset plastic. This unitizes the assembly and prevents loosening and leakage from shock and vibration.
- Augments press fit.
- Recommended for parts that will need subsequent dismantling, for eg: retention of bearings on shaft and into housing.
- Prevents loosening and leakage from shock and vibration.
