Wrapped spring steel plain bearing | Requires maintenance | DIN 1498 | DIN 1499

Bearing properties

  • FER-MET® is a spring steel plain bearing without integrated sliding material. Lubrication of the bearing point is necessary. Very high load capacity and impact resistance for heavy-loaded applications with impact loads. Very wear-resistant. A standard gap design with a straight slot and without chamfer inside [EG], but can also be manufactured with other slot shapes if required.
