What are rubber-coated spacers?

Rubber-coated spacers hold and pull the strip during longitudinal cutting. They consist of two parts:

  • Core: the metal part of the piece, with the same treatment as the knife.
  • Rubber: a synthetic compound in nitrile or polyurethane, according to the material to be cut.

Industrial functions

Rubber-coated spacers perform four functions:

  • Pulling: they move the coil along the longitudinal cutting line.
  • Ejection: they direct the strip's exit direction.
  • Lifting: they guide the strips to prevent marking.
  • Support: they prevent strip buckling and improve cut quality.

Main features of our rubber-coated spacers

We manufacture them with the following characteristics:

  • Hardness from 60 to 90 Sh, for optimum pulling without marking the strip.
  • A wide range of colours, which make assembly easier for the operator.
  • Thickness tolerance of ±0.001, for a perfect fit.
  • Lightened designs that reduce weight when assembling the shear.
  • High resistance to oil and abrasion, for coil cuts with lubricants.

Frequently asked questions

Common questions

What is a rubber-coated spacer?

It is a spacer covered in vulcanised rubber that protects the surface of the strip and prevents marks during cutting and winding.

Do you manufacture them to size?

Yes. We manufacture them in the diameter, thickness and rubber hardness that your cutting line requires.
