Loctite® 641 Bearing
For medium strength retaining of bearing, bushes, oil seals, etc.
Increases the reliability of slip-fitted and light press-fit parts preventing fretting, corrosion between bearing surfaces and seals against leakage
Recommended for parts that need subsequent dismantling e.g. bearings and bushes retained by this product can be readily removed from shafts or housings by ordinary tools and methods

Loctite Retaining Compound Liquid
The Loctite yellow medium strength, 50ml retaining compound liquid is designed to bond cylindrical fitting parts, particularly where disassembly is required for servicing operations. This product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. The liquid is composed of methacrylate and provides robust curing performance. It is ideal for parts that need subsequent dismantling. It increases the reliability of slip-fitted and light press-fit parts preventing fretting, corrosion between bearing surfaces and seals against leakage.
