Protective Covers for Conveyor Rollers
Reduce noise, absorb impact, and extend roller life. The higher the hardness rating, the longer the covers will protect rollers in demanding applications.
Heat-shrink covers conform to the shape of your roller when heated. Slide-on covers slip over the roller. For easier installation, use lubricant and an air nozzle.
PVC is for use in corrosive environments. Polyurethane has a high-friction surface for high speeds and inclines.
FDA-compliant covers are safe to use for conveying food and beverages
Lubricant is water based and loses its lubrication properties upon drying to ensure covers retain a snug fit.
Connect air nozzles to a source of compressed air to create a cushion for sliding covers onto the roller.

Loose-Fitting Protective Covers for Conveyor Rollers
Covers fit loosely over the roller to allow packages to accumulate. Rollers can continue spinning inside the cover without causing damage to packages.

Transfer Guards for Conveyor Rollers
Keep small items moving smoothly down a roller conveyor. These guards cover the gap between rollers so items don’t fall through or get jammed. They consist of a flat plate with flexible legs that snap in place between your rollers.
To figure out how many guards you need, consider how wide your rollers are. For rollers wider than 12”, you’ll need multiple. Trim guards that are too long using the installation tools (sold separately). Use the leg cutter to remove the leg just past the width you need. This gives you enough room to use the guard cutter to trim the guard down. For a proper fit, you can’t trim these shorter than 4”.

Protective Covers for Conveyors
Protect conveyed material from dust, debris, and other contaminants. All of these covers are FDA compliant for food and beverage conveying.
PETG plastic covers are more chemical resistant than ABS plastic but not as scratch resistant.
Metal-detectable ABS plastic covers are best when metal detection and retrieval are essential, such as in food processing applications. Made with metal additives, they set off metal detectors if any part falls into your line, so it won’t leave your facility.

Chemical-Resistant Heat-Shrink Tubing
Use this tubing where wire and cable may be exposed to chemicals, oil, and acids.
PVC plastic tubing is more chemical resistant than rubber. It also resists UV, so it won’t fade or discolor when exposed to sunlight. Store tubing at 70° F or lower to avoid premature shrinkage.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown. The higher the dielectric strength of a material, the better it is for preventing electricity, heat, or signal from dissipating from wire and cable.
