Rubber rollers for wood sanders
Rollers, manufactured with proper tolerances to ensure consistent traction, uniform pressure, and long life, are used on calibrating machines, belt sanders, and edgebanders.
The rubber roller is the driving and pressing part of woodworking machines: it feeds the panel into the machine, keeps it in contact with the abrasive belt and absorbs surface irregularities during calibration and sanding.
Vulcanized rubber replaces hard surfaces where grip is needed without marking the material: on veneered edges, on laminated panels and on solid wood, where a roller that is too hard would leave scratches or marks.
The key elements for these rollers are:
- Compound: wear-resistant rubber, resistant to heat and processing oils is chosen
- Hardness: chosen based on the function, choosing lower for delicate surfaces and higher for dragging and calibration
- Metal core: turned and dynamically balanced tube
- Primer: quality adhesive to prevent detachment under load or heat
- Tolerances: Accurate cylindricity and concentricity for superior performance
The advantages that A.Piovan offers are:
- Durability: anti-wear compound that maintains constant diameter and hardness for a long time
- Quiet: The rubber absorbs drag vibrations, reducing noise and stress on the bearings.
- Uniform grip: calibrated surface along the entire length, without weak contact areas
- No marks on wood: lower hardness for veneered or lacquered surfaces
