Securing Motor Mounting Bolts Against Vibration and Torque

  • Post last modified:November 15, 2025

Motor mounting bolts are the crucial connection between the power source and the machinery. They are under continuous stress: constant high-frequency vibration from the rotating component, massive starting and stopping torque loads, and potential operational heat. A failure in these structural bolts leads immediately to misalignment, belt or chain issues, excessive wear on couplings, and catastrophic operational failure.

Don’t compromise the stability of your power source; anchor the motor with the toughest chemical lock.

INCURE Re-Lok™ B72 Red Heavy Duty Threadlocking Adhesive

For securing structural components like motor feet to a frame or base plate, maximum permanent strength is non-negotiable. The INCURE Re-Lok™ B72 Red is a high-strength, high-temperature anaerobic adhesive engineered to secure fasteners against the most severe dynamic loads and continuous vibration found in industrial and automotive applications.

Feature & BenefitTechnical Insight for Motor Mounting BoltsConversion Value
High Strength, Permanent LockProvides the maximum breakaway and prevailing torque, permanently securing fasteners up to M36 against loosening from high torque and constant vibration.Maximum Stability: Achieve an unshakeable bond that prevents motor walk and belt tension loss.
Superior Shock and Vibration DampingCures into a solid, rigid plastic that fills all thread gaps, effectively damping high-frequency vibration and preventing fastener back-out.Stop the Movement: Eliminate creep and ensure the motor remains precisely aligned, maximizing component lifespan.
Extreme Thermal ResistanceWithstands continuous operating temperatures up to 230°C, maintaining full strength even near hot running motors or exhaust components.Heat-Proof Confidence: Ensure the chemical lock remains robust under peak thermal conditions.
Contaminant ToleranceDesigned to cure quickly and reliably on surfaces that are not perfectly clean, tolerating minor residue from assembly oils or lubricants.Reliable Assembly: Get dependable performance without requiring excessive, time-consuming preparation.

Application Steps: Securing Motor Mounting Bolts for Structural Integrity

Preparation (Mandatory): Due to the critical nature of motor alignment, the threads of both the bolts and the receiving bore must be meticulously cleaned. Use a wire brush and a heavy-duty degreasing solvent. Ensure all surfaces are perfectly dry and free of old grease or oil.

Application: Apply a continuous, liberal bead of Re-Lok™ B72 Red around the entire circumference of the bolt threads, focusing on the area that will be engaged.

Assembly: Immediately install the motor and thread the bolts. Using a calibrated torque wrench, tighten the bolts to the manufacturer’s specified value. Proper clamping force is essential for seating and alignment.

Curing Time (Critical): Allow a full 24 hours for the adhesive to achieve its maximum high-strength and load-resistant cure. The machinery must not be operated or subjected to full torque loads until the full cure time is complete.

Stop risking catastrophic machine failures and secure your structural components with the toughest chemical integrity.
