Liquid sleeve retainer, or bearing mount, strengthens the fit between non-threaded, smooth, cylindrical assemblies that rely on tight clearances and friction to maintain the connection. Designed for high-temperature and close-fit applications.


Features:

  • Creates a tighter fit and prevents slippage when applied to non-threaded, smooth assemblies
  • Withstands higher temperatures than other bearing mounts - up to 400 F
  • Designed for tight clearances
  • Prevents treated parts from corroding
  • Requires heat and, for the tightest fits, a press or puller to disassemble
  • Made in the USA


Specs:

  • Application: press-fit or slip-fit assemblies with clearances to 0.007" diameter
  • Quantity: 0.20-fl oz tube (6 mL)
  • Sheer strength: 3,000 psi
  • Fixture cure (time required to become tacky): 1 hour
  • Full cure (time required to reach full set): 24 hours
  • Temperature range (endurance limits of threadlocker): -65 F to 400 F


Applications:
  • Bushings
  • Bearings
  • Oil seals
  • Ring gear bolts and differential lock pins
  • Cylinder sleeves
  • Valve guides
  • Valve seats
  • Woodruff keys
  • Gears
  • Pulleys
  • Liner assemblies


The following diagrams illustrate the use of Loctite sleeve retainer. Arrows on the gear and shaft illustration show the effects of heating and cooling. The parts can be assembled more easily if the gear is heated or the shaft cooled to make a looser fit between the two parts.

diagram of sleeve retainer applications


Loctite Sleeve Retainer 640 liquid is applied to the surfaces of parts to be joined. By filling up empty space (microscopic voids) on the surfaces of the parts, the sleeve retainer increases the area of contact between them, creating a tighter fit and preventing slippage.


Withstands temperatures up to 400 F, whereas standard anaerobic bearing mounts withstand temperatures only up to 300 F.


To disassemble, heat to 500 F (requires about 5 minutes with a torch) to loosen the sleeve retainer; then remove while sleeve is still hot, using a press or puller, if necessary.


This sleeve retainer is anaerobic (hardens in the absence of air) and requires contact with an active metal to cure. Active metals (those that tarnish, corrode or rust) include brass, copper, bronze, iron, soft steel and nickel. If both parts to be joined are made of inactive materials, Loctite Klean 'N Prime primer must be applied to one of the surfaces for curing to occur. Inactive materials include plated parts, stainless steel, galvanized steel, magnetite steel, pure aluminum, titanium, magnesium, gold, silver, plastic, cadmium, Iconel, zinc, natural or chemical black oxide and anodized aluminum.


Klean 'N Prime can speed the cure rate of Sleeve Retainer 640. This is especially helpful when you are applying the sleeve retainer to any material, active or inactive, in colder temperatures (below 70 F). Klean 'N Prime also improves the performance of the sleeve retainer in applications with larger clearances by filling some of the space between parts.


Note: If used with Klean 'N Prime primer, sleeve retainer may reach fixture cure in 30 seconds; in this case, it is essential that parts be assembled quickly.

Lowest price for the good stuff - Loctite 640 - in the 0.2 fl oz tube. Quick shipping, order well was packed - I'm a satisfied customer


Comments
I used the adhesive to secure a steel sleeve in a cast iron bore on a 4x6 bandsaw. The sleeve is still holding and the bandsaw works much better now that the spindles are parallel under load.

Can't beat Loctite for fastener retention. Used it to retain a sleeve in a motorcycle which gets heat cycled a lot and, it dies the job well. Highly recommend this. Pudding was a breeze and, I received it quickly. Great ordering experience.
