Save Money by Re-covering Worn Parts

Nothing lasts forever. So when a roller, actuator or lifter starts wearing out, what's your first step?
The solution actually starts before the part breaks down. Many operators may run a part or roller well beyond its lifespan, which can cause a wide variety of problems. For example, if they're using the roller to apply an adhesive to a part, the application will be uneven. If being used to drive a belt, the belt can slow down or may have difficulty tracking, which will lead to wear or damage on other components of the system. Not to mention producing an inferior product.
A part needs attention when it starts slipping, sliding, failing to grip or failing to drive.Sometimes, in an effort to delay the inevitable, operators perform quick fixes like placing tape over it to counteract the wear. But that's simply a Band-aid approach. Operators who do that are simply fooling themselves into thinking they've solved the problem.
For the most part, their efforts area misplaced desire to do the best for their employer. They want to keep the job running and the machine in service but don't understand that by not replacing the parts in a timely fashion, they're actually doing more harm than good.
How can you tell if a rubber covered part needs to be replaced or just re-covered?
Consider a roller. If the metal core of the roller is undamaged, in most cases, there is no need to replace it. You simply need to put a new rubber covering on it. That same logic applies to any part, not just rollers. If there's no damage to the roller, gripper, or other metal pieces that the rubber is attached to, more than likely, you just need to re-cover them, not replace them.
To determine damage, examine the metal pieces. Are there any wear marks? Has it thinned out in spots? Is the core shaft marked where the bearings roll on the roller? If not, then you don't need to replace that steel core, just the rubber on top of it.
Thisis where companies can save a lot of moneyby replacing the rubber surface, not the whole metal core. A reputable vendor will take your specifications and, using the original metal pieces like the roll core or the metal subframe of the part, re-cover it with new rubber or polyurethane.
More information, the better
Vendors need to understand as much about the operating environment of this item as possible. The type of information you need to share may include:
- Where and how is the part used?
- How hot does the part or item get?
- Does it come into contact with any chemicals or fluids?
- Is it a food-grade application where the item comes into contact with food or food products? If so, be sure to let your vendor know so they will use a material suitable for food contact. Also, be specific about the types of food the
