When a piece of equipment vibrates there is always the chance that nuts and bolts may loosen. As such, checking that bolts are correctly torqued down is an essential component of routine maintenance.
This task can be tedious, but not completing it correctly can result in unscheduled shutdowns or even injuries. This is why Bearings International has partnered with Dykem to distribute the brand’s Cross-Check Torque Seal locally. It is a tamper-proof vibration-warning indicator paste that can improve safety and reduce inspection time.
Bearings International product manager, Richard Lundgren, says that applications for Cross-Check Torque Seal range from vehicles to conveyor belts. “The artisan literally draws a line of the paste from the bolt head and along the threads of the screw, once perfect torque has been achieved,” explains Lundgren.
At the next inspection, the artisan simply checks to see if the brightly-coloured mark is still in alignment. If not, action can be taken on that specific bolt, instead of having to retighten all of the bolts, thereby speeding up the process and reducing the possibility of any loose bolts being missed.
With its excellent adhesion to all types of materials, including steel, the indicator paste comes in a range of eight colours for high visibility. It is also fluorescent under UV lighting. Lundgren stresses: “The safety aspect of this product cannot be overstated, especially when one considers the potential danger of a bolt coming off a kilometre-long conveyor belt in a factory where people are working.”
Lundgren anticipates increased demand from manufacturers, agricultural organisations, mines, and even the power-generation sector. “It’s a product that should be in every workshop, maintenance facility, or warehouse,” he concludes.
