LOCTITE 640 High-Strength Sleeve Retainer, High-Temperature, High-Stength, Anaerobic Adhesive, For Large Diameter Components, Active Metals | Green, 6 ml Tube (PN: 487235)

Used to hold my wheel bearing in place on my moped. So far so good!

I have used Loctite for years and mostly very successfully even with heavy industrial use. This sleeve retainer didnt work so well for me on a fairly simple fan to motor shaft sleeve. It wouldnt cure either by warming up both parts and/or attempting to let it setup for more than 24-hours. I was a bit disappointed with this product, I dont know it the clearance was too great for this particular job.

Only brand I trust is loctite

Wanted to clean of old bandsaw’s rubber tire the “easy” way. I did but in the process enlarged the bandsaw’s bearing hole. The loctite product says it can fill up some of the space between the bearing and bearing hole. Well it did and 5 years have passed and the bearing is still in there.

Great product. A translucent green liquid that is strong but also light enough that it can wick into tiny cracks. Dries relatively clear and is barely noticeable. Starts to bond within minutes, but total cure time is about a day. Used this on a loose and jiggly metal part and its solid as a rock now.

This worked really well to secure my dipstick tube into the engine block.

Not something you can find at local home improvement or hardware store. I needed this for an RC helicopter pinion gear gluing to the motor shaft. The torque was enough to break high strength red Loctite 271, but this green 640 stuff hasnt broken yet.

It is the standard for a reason

good value

its a great retainer for metal to metal contact. Would recommend and will buy again Thank you very much. RauL
