POM-MET®

Wrapped composite sliding bearing steel / POM | low-maintenance | With lubrication pockets | DIN 1494 / ISO 3547

Bearing properties

POM-MET® is a low-maintenance composite sliding bearing with a POM coating. Initial lubrication is required. Both oil or grease lubrication are possible. Due to the lubricant pockets, relubrication intervals are significantly reduced! Suitable for all sliding movements, good load capacity, robust and resistant to dirt.
