Rubber roller

Wide belt sanders

Unlike inflexible steel rollers, different sanding results can be reached depending on the hardness of the rubber.

The hardness of the rubber is measured and given in °Shore (degrees Shore). The hardness of rubber rollers is measured according to the Shore A-scale according to DIN 53505. In this measurement, it is determined how deep a metal tip with a defined shape can be pushed into the rubber. The lower the hardness in Shore, the softer the rubber.

Rubber rollers as well as steel rollers are usually ribbed (among other uses, for holding the sanding dust, for cooling and for harmonization of the sanding structure).

Guideline on rubber hardness for wood sanding:

  • 70 - 95° Shore: very hard, suitable for calibrating
  • 60 - 70° Shore: sanding/calibrating
  • 35 - 55° Shore: 'soft' sanding
  • 20 - 30° Shore: very soft, Finish-sanding, final sanding e.g. before painting
