SKF housings for paper machines are made of grey cast iron.
Paint, corrosion protection
SBFN, SBPN and SDM housings are painted blue (RAL 5007) using a water based alkyd/acryl paint. The paint protects the housings in accordance with ISO 12944-2:1998, corrosivity category C2. Housings can be repainted with most water or solvent based 1- or 2-component paints. The housings can also be supplied painted according to customer specification (→ Housing variants).
Unpainted surfaces are protected with a solventless rust inhibitor.
