Tape-on roller groove sleeves (also called E-Z Grooves and Add-A-Groove) allow you to add a groove or a number of grooves in any configuration to conveyor rollers from 1.9" to 50mm diameter. Lets you add belt power to gravity rollers quickly and economically.
The grooves can be round, flat (with or without a crown) or vee shaped. Our standard round groove is 1/4" (6.3mm) wide and .18" (4.8mm) deep. We can also machine the grooves to your specs, or you can machine them yourself.
The material is heavy but springy PVC with .23" (6mm) wall thickness. This limits the grooves depth to a maximum of .18" (4.8mm) deep.
Available IDs, all with approximant tolerance +/- 080" (2mm):
Since PVC is not an extremely hard material, it may abrade if belts rub hard against the groove edges at an angle. Therefore, if your belts impinges on the groove at angle as in lineshaft conveyors or curves, test the sleeves for a few months before buying large quantities.
There is 1/32" (0.8mm) wide lateral slit (perpendicular to the grooves) in the PVC sleeve. Internal stress in the sleeve make it want to close, so the slit allows the sleeve to snap tight against the roller as if it were spring loaded. The belts are not affected adversely by the slit even if the slit is not fully closed as on 50mm rollers. It can be open as much as 1/8" (3mm) without causing any wear on the belt.
There are two primary ways to attach the groove sleeves to rollers, two-sided tape or epoxy:
Tape-on Roller Groove Sleeve
Two Tape-on Roller Grooves
Multiple Roller Grooves
E-Z Groove opened with Screwdriver
Double Groove Sleeve
Epoxy-on Flat Belt Sleeve
