What is Loctite 603 used for?

It is designed for bonding cylindrical metal parts, such as roller bearings, bushings, and shafts into housings.

Can it be used on lightly oiled surfaces?

Yes, Loctite 603 is oil-tolerant and cures effectively even when surfaces are not fully degreased.

How does this retaining compound cure?

It is an anaerobic adhesive that cures in the absence of air between close-fitting metal surfaces.

What is the maximum gap fill for Loctite 603?

This low-viscosity adhesive is suitable for close-fitting joints with a gap fill of up to 0.15 mm.

How do you disassemble bonded components?

Apply localized heat of 250 °C to soften the cured retaining compound and disassemble while hot.

High strength cylindrical bonding Loctite

Practical benefits

Excellent vibration and shock resistance: You prevent the loosening of bearings and bushings under continuous mechanical stress and impact.
Easy penetration into gaps: You reinforce tight press fits effortlessly thanks to the low-viscosity formula designed for close tolerances.
Effective oil tolerant bonding: You achieve dependable joint strength even when parts retain light oil residues during assembly.

In a nutshell

The right choise for

With Loctite 603, you securely retain cylindrical metal components such as bearings, bushings, and shafts into housings. Supplied in a practical 50 ml bottle, this liquid retaining compound fills gaps up to 0.15 mm and reliably prevents loosening, slipping, and fretting corrosion under heavy vibration or shock loads. Thanks to its oil-tolerant anaerobic formulation, you achieve high-strength bonding even when surfaces retain slight oil residues. It allows you to reinforce press-fit and slip-fit assemblies quickly during machinery maintenance and repair without extensive degreasing.
