Rolled plain bearings made of heavy-duty bronze AW-TM, AW-TMH, AW-TMD
AW-TM plain bearings are the Hercules of plain bearings | Heavy-duty bronze
They have been specially developed to meet the highest demands. Heavy-duty bronze bearings have exceptional characteristics and allow higher load capacities, operating temperatures and sliding speeds. Their corrosion resistance and long service life enable enormous service lives.
-
- Plain bearing made of heavy-duty bronze.
- Suitable for applications with high loads.
- Versions with smooth running surface, with diamond-shaped lubrication pockets or perforated deposits in the running surface, ready for installation. Versions according to customer drawings with lubrication grooves etc. are also available.
- Suitable for rotating and oscillating movements in the mixed friction range for grease-lubricated applications.
- Due to the load values, wear behavior and higher PV value, this material is ideal for heavy construction machinery, oil and gas drilling equipment, heavy military vehicles, production machinery, steel mill rollers, injection molding machines and marine applications.
Versions:
- AW-TM: Plain bearing made of solid heavy-duty bronze strip. Suitable for applications with high loads. For example in construction machinery, agricultural machinery, crane construction and vehicle construction.
- AW-TMD: Design as AW-TM, but with diamond-shaped lubrication pockets. Not available as flanged bearings.
- AW-TMH: Plain bearing made from perforated heavy-duty bronze strip. The perforated pockets allow a larger storage volume for the lubricant. This results in longer lubrication intervals. Not available as a flanged bearing.
- AW-TMG: Design as AW-TM, but with lubrication grooves.
- AW-TMGH: Plain bearing made of perforated heavy-duty bronze strip (like AW-TMH) with additional lubrication groove.
