VIBRALOCK® is a patented new mechanical locknut system that will make annual inspection and re-torque checks of your structural bolts redundant.

Vibrations – or oscillation - in industrial equipment can be a symptom, or cause, of a problem, or it can be associated with normal operation. Vibrations can accelerate machine wear, consume excess power, and cause equipment to be taken out of service, resulting in very expensive and un-planned downtime.

Less tangible consequences are general safety issues and diminished working conditions. Imbalance, misalignment, wear and loosening are the most common causes that lead to unwanted vibrations. For some applications, vibrations are unavoidable, or even an essential part of the equipment’s function.

Regardless of whether the vibrations are desirable or not, it is very important to use components that can withstand the oscillations. If your bolted connections cannot handle the vibrations, you are doomed to spend countless and ex-pensive man-hours on regular maintenance checks throughout the equipment lifecycle.

VIBRALOCK® is a patented new mechanical locknut system that will make annual inspection and re-torque checks of your structural bolts redundant. This superior product is currently under DNV GL certification for proof of the concept.

In late 2021, Bondura Technology AS performed the laboratory test of VIBRALOCK® at the University of Stavanger with EXCELLENT results. A copy of the test results can be found below.

The VIBRALOCK® technology is based on the use of two nuts working on different thread diameters and pitches. No loosening can occur due to the contact pressure between the two nuts and difference in pitch. With VIBRALOCK® your maintenance work and inspection regime will be very different compared to conventional bolting solutions. Man-hours needed and your overall cost of operations will significantly be reduced.
