GorillaPro® AR200 is a high-strength, anaerobic adhesive designed for retaining close-fitting parts like shafts, bushes, pulleys, and rotors. It is particularly well-suited for use on oily surfaces, eliminating the need for additional cleaning. This formula is recommended for press-fit applications that demand tighter machining tolerances. GorillaPro® AR200 demonstrates exceptional resistance to heat, corrosion, vibrations, water, gasses, oils, hydrocarbons, and various chemicals.

Features & Benefits

Product Benefits
  • Available in slip fit or press fit formulas
  • Best choices for non-threaded, cylindrical applications
  • Fills inner space between components
  • Cures into a hard thermoset plastic that resists loosening
  • Color coded for grab-and-go
  • Better load transmission and performance
Product Features

Reliable Retaining Compounds
Retaining compounds durably and reliably retain bearings, shafts, studs, and flanges. In general, the need to dismantle these joints is not required, and GorillaPro retaining compounds are designed for high strength to meet this requirement. They achieve uniform stress distribution throughout the joint, making it possible to withstand dynamic and static loads with equal ease.

  • Retaining compounds can fill small gaps within twomated assemblies which allows for less costly part designs
  • Friction corrosion is avoided
  • Replaces clamp rings, set screws, and snap rings, reducing annual maintenance spend

High-Performance MRO Solutions 
Proactive maintenance can help prevent costly unplanned downtime. It’s a challenge keeping up with maintenance activities while keeping teams trained, equipment operating, and driving productivity. With a full complement of maintenance adhesives, repair epoxies, lubricants, and sealants, GorillaPro retaining compounds can repair and improve the reliability of almost any piece of equipment or machinery.

Product Attributes
  • Fast Flow: Lower viscosity works best for augmenting press-fit applications
  • Press Fit: Great for bushing and bearing mount housings
  • Cost Savings: Replaces clamp rings, set screws, and snap rings

Applications & Uses

Compatible Substrates & Surfaces
Cure Method
Application Instruction

Surfaces to be bonded should be clean, dry and free of grease. Product should be applied in enough quantity to fill all engaged threads or gap. The product performs best in thin bond gaps. Very large gaps may create voids that will affect the cure speed and overall strength. Good contact is essential. It is recommended to confirm compatibility of the product with all substrates prior to use. This product is not recommended for use with strong oxidizing materials. Where aqueous washing systems are used to clean the surfaces before bonding, these aqueous washes can affect the cure and performance of the adhesive. This product is not normally recommended for use on plastics, users must check compatibility of the product with such substrates.

Curing Performance
The rate of cure will depend on environmental conditions and the substrates used. The gap of the bond line will affect set speed. Smaller gaps tend to increase set speed. Activators may be applied to further improve set speed, but may also impair overall adhesive performance.
