Overview

LOCTITE® 609 is a green, medium strength retaining compound designed for the bonding of cylindrical fitting parts. The product cures in the absence of air between close fitting metal surfaces. Typical applications include rotor to shafts in fractional and subfractional horsepower motors. Locks bushings and sleeves in housings on shafts.

  • Medium Strength (2300 Psi)
  • Fills Gaps upto 0.1mm
  • 150oC Service Temperature
  • Prevents loosening and leakage from shock and vibration

Features and benefits

  • Prevents loosening: It fills all gaps between the cylindrical components and cures into a hard thermoset plastic. This unitizes the assembly and prevents loosening and leakage from shock and vibration
  • Augments press fit
  • Recommended for parts that will need subsequent dismantling, for eg: retention of bearings on shaft and into housing

FAQs

  What is the optimum fit for using anaerobic retaining compounds if I want to maximize the shear strength?

The optimum fit for thinner products (low viscosity) like LOCTITE 603 and LOCTITE 609 is 0.025 mm to 0.08 mm, and for thicker products (high viscosity) like LOCTITE 638 and LOCTITE 648 it is 0.05 mm to 0.1 mm.

  What is the recommended surface roughness for cylindrical components being fitted with LOCTITE retaining compounds?

The recommended range for surface roughness of the cylindrical parts is 0.8 micron to 3.2 micron. You can also go for surface roughness as high as 50 micron if eccentricity is not a concern.

  What is the correct procedure for applying LOCTITE retaining compounds?

For slip fit assemblies, apply to only one of the parts and assemble with a twisting/turning motion. For tight/close fitting assemblies with minimum clearance, apply to both parts.

  We need to lock bearings in place but there will be exposure to oils. Will LOCTITE retaining compound also seal the joint?

Yes, all LOCTITE retaining compounds offer the dual benefit of lock and seal.

  Can LOCTITE retaining compounds migrate to and jam other parts?

No. LOCTITE retaining compounds are thixotropic in nature, which means that they are quite viscous unless a shear force is applied. Hence, LOCTITE retaining compounds will not flow to other areas of the machinery.

  Do I need to use a Primer with a LOCTITE retaining compound?

We recommend the use of primer where both the parts come under the category of 'inactive surfaces'. These metals lack the iron or copper content and thus the metallic ions that are required to fully cure the product within 24 hours. These inactive surfaces include plated parts, stainless steel, galvanized steel and anodized aluminium to name a few. On the other hand, in case both or at least one part is an active metal, then there is no need to use a primer to ensure full cure, which is typically within 24 hours at room temperature.

  How can a cylindrical assembly fitted with LOCTITE retaining compound be disassembled?

To disassemble an assembly fitted with LOCTITE retaining compound, just pull the assembly apart mechanically. If necessary, apply localize heat (230 degrees celsius for 5 mins) and pull while the assembly is hot.

  We need to retain a worn shaft and also lock it into a housing or bearing. Are there any solutions for this?

Yes. With LOCTITE 660 retaining compound, shafts with radial gaps less than 0.5 mm can be locked. In case of badly worn shaft, the repair can be done with LOCTITE Superior Metal.
