BRO-MET®

Wrapped bronze sliding bearing with lubrication pockets/ CuSn8P (DIN 17662) | Low-maintenance | DIN 1494 / ISO 3547

Bearing properties

BRO-MET® is a low-maintenance bronze plain bearing. However, initial lubrication is required—both oil and grease lubrication are possible. Due to the lubricant depots, relubrication intervals are significantly reduced! High load capacity and strength with low wear, suitable for rough operation, corrosion resistant.
