How to Increase the Lifespan of Your Conveyor: The Smart Tips

Correct tracking of the belt is important. Most conveyors are built with PVC or PU belts. These belts need to be installed and tracked correctly after first installation. A lot of people do this with every conveyor before it leaves the factory. Therefore no major adjustments should be needed after the conveyor is set up on-site. It is important that you double check the tracking of the belt before the conveyor starts the production. It is also a good idea to periodically check if the belt tracking is correct. This will greatly increase the serviceable lifespan of any conveyor belt.

Conveyors are designed with heavy-duty drive and idler rollers. These rollers are slightly crowned according to belt manufacturer’s specifications. All conveyors are delivered with belt stretch/tracking adjustment bolts on either side of the idler rollers. To adjust tracking, simply loosen the bolt that holds the idler side-plates in position and tighten the adjustment bolt on the side the belt is moving towards too. In other words, if the belt is to far on the left, tighten the left adjustment bolt. The amount of tension needed depends on the size and speed of the belt. In general, it can be said that only small adjustments will be needed. A quarter turn of the adjustment bolt can make a huge difference. So be careful not to over compensate. Give the belt a bit of time to settle in its place and make fine adjustments if necessary. After the belt has settled in, don’t forget to tighten the side-plates. Some conveyor experts observe a periodical check to make sure the tracking is still okay.

Tracking of a belt on a conveyor is normally done via slightly crowned rollers. This approach works really well in most applications and conveyors utilizes this approach on all standard conveyors. There are however, a few circumstances where this approach is not reliable and other solutions need to be implemented. Conveyors with a width to length ratio of less than 1:2 for instance will not track properly with crowned rollers. Conveyors where the direction of travel changes should also not rely on crowning.

The Smart Strategy – A Conveyor with a Tracking Strip

It is now possible to order belt conveyors online where the belts themselves are fully guided. This is done via a tracking strip joined onto the underside of the belt, which in turn runs in the base extrusion T-slot and a location groove machined into the rollers. This feature offers the opportunity to integrate standard belt conveyors into an automation solution, which up to now would have demanded the use of a modular belt conveyor. In most cases those would be substantially more expensive.

With clever and innovative solutions such as the fully tracked belt conveyors, several online conveyor shops are again able to help you save money. Fully guided conveyors can still be shipped within two working weeks, fully assembled!
