Wrapped bronze sliding bearing - with perforations

Technical details BRO-MET® / L

Wrapped bronze sliding bearing
CuSn8P (DIN 17662)
DIN 1494 / ISO 3547
With perforations



  • High load capacity and stability at low abrasion. Because of perforations lubrication clearances are reduced to a minimum!


  • Support material CuSn8P (DIN 17662)

Material properties

  • Specific load capacity static ≤ 120 [N/mm2] bei max. 0,01 m/s
  • Specific load capacity dynamic ≤ 40 [N/mm2] bei max. 2,0 m/s
  • Sliding speed ≤ 2.5 [m/s] depending on lubrication
  • Friction value *** 0.05 [µ] to 0.20 [µ] depending on lubrication
  • Temperature strain – 40 [°C] to + 250 [°C]
  • Max. PV-value 2.8 [N/mm² x m/s]

Tolerance Details

  • Housing Ø H7
  • Bushing inner-Ø after mounting H9
  • Shaft tolerance f7 to h8

Shaft material

  • Steel, hardened or untempered, surface roughness ≤ Rz 6.3

Mounting Advise

  • Housing: Mounting bevel min. 1.5 mm x 15-45°
  • Shaft: Mounting bevel 5 mm x 15°, edges rounded
  • The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.


  • BRO-MET®/L is a low-maintenance bronze sliding bearing, primary lubrication is necessary. Oil or grease lubrication is possible. Due to lubrication pockets lubrication clearances are reduced to a minimum

Range of application

  • Hydraulic cylinders, construction machines, crane construction, agricultural machines (impact loading)
