Loctite-586 - Improvement in the frictional bond
Bearing installation using Loctite-586
The roughness of the surfaces to be joined should not exceed a value of Rt 65 (peak-to-valley height) since shear strength will decrease at greater roughness values.
Theoretically, the quantity required for a layer of 0.1 mm is 100 ml/m². However, if the layer is to be applied by hand, it is advisable to use double or triple this quantity, since dosage by hand cannot always be absolutely accurate.
The following points must be observed during installation:
- Cleaning of contact surfaces with a commercially available cleaning agent to remove any oil or grease
- Inactive surfaces must be pretreated with the T 747 activator. Loctite-586 must only be applied to the nonactivated surface. If both sides are active, or if Loctite is applied onto the activator, premature curing may result (drying within a few minutes).
- Loctite must be applied with a stiff brush onto one surface
- Spigot locations must not come into contact with Loctite since this would render later dismantling difficult. They must be coated with a separating agent, e.g. wax or grease.
- Tightening of fastening bolts. Loctite will start curing as soon as 2 hours after positioning of the bearing. If it is not possible to fully tighten the bolts during this period, manual tightening will suffice as a preliminary solution.
- Through holes and tapped holes have to be protected against Loctite
