Matel spacer is used on slitter shaft to adjust different distance between slitting knife according to needed width of coiling strips.
Same high pricision as slitting knife's;
Reasonable price, not as expensive as knife of raw material;
Wear resistance, but lighter for machine shaft to ensure higher precision of slitting strip and easier assembling.
