Attach adhesive-mount coatings—also known as lagging—to conveyor pulleys without removing them from your system, which is how you apply traditional coatings. For optimal bonding strength, apply the primer and mix equal parts adhesive and activator. Apply two layers of the adhesive mixture.

To Order—You’ll need the same amount of adhesive and activator. One can of adhesive and one bottle of activator will cover up to 314" of surface area. To find your pulley’s surface area, multiply your pulley’s diameter by its width.

Determine how many cans of primer you’ll need by multiplying pulley diameter by pulley width (in inches). One can will cover 3,220" of surface area.

Slide these coating strips into metal retainers (sold separately) that you attach to your pulley—they add friction that helps conveyor belts stay on pulleys and are replaceable when they’re worn. Unlike traditional coatings, you don’t need to detach the pulley from your system to apply them. Each strip consists of rubber bonded to a metal backing plate to prevent it from separating from the pulley surface, which can happen to adhesive-mount coatings. When the strips wear out, pull them out and slide in new ones. They’re also known as lagging.

These rubber strips protect pulleys from wear and damage, helping them last longer. They have a diamond tread that sheds sand, gravel, grain, and other debris to prevent material buildup and maintain traction on the belt. Use them in dry and dirty environments.

Pair tapered strips with straight strips to give your pulley a slightly concave surface, which improves belt tracking by directing the belt back to the pulley’s center if it starts to wander.

Perforated-backing strips bend to fit any diameter pulley 12" and over, so you don’t have to keep strips for different diameter pulleys on hand to replace damaged ones. They’re interchangeable with standard coating strips that are made for a specific pulley diameter.

Bolt or weld retainers onto the surface of your pulley. Single-sided retainers only have lock-down tabs on one side, so use them to mount the first and last strips. Double-sided retainers have lock-down tabs on both sides. Use them on the majority of your pulley’s diameter.

To Order—For flat surfaces, check the chart or follow the 4 steps below to determine how many straight strips and retainers you’ll need to cover your pulley.

1. Divide the pulley’s diameter (in inches) by 2.

2. Multiply the answer by the pulley’s width, and then add 6.

3. Divide the answer from step 2 by 72 and round up. This is the number of straight strips and double-sided retainers you’ll need.

4. Take the answer from step 3 and divide it by 4, then round up. This is the number of single-sided retainers you’ll need.

For slightly concave, or crowned, surfaces, pair tapered strips with straight strips. The number of tapered strips you will need is equal to your pulley’s diameter (in inches). To determine the number of straight strips you’ll need, follow the 4 steps below:

1. Divide your pulley’s diameter by 2.

2. Subtract 20 from the pulley’s width.

3. Multiply the answer from step 1 by the answer from step 2, and then add 6.

4. Take the answer from step 3, divide it by 72, and then round up. This is the number of straight strips you’ll need.
