Wrapped bronze sliding bearing - with lubrication pockets

Technical Details BRO-MET®

  • Wrapped bronze sliding bearing
  • CuSn8P (DIN 17662)
  • DIN 1494 / ISO 3547
  • Low-maintenance
  • With lubrication pockets
BRO-MET BMZ

Properties

  • High load capacity and stability at low abrasion, suited for rough operation, corrosion resistant.

Materials

  • Support material CuSn8P (DIN 17662)

Material Properties

  • Specific load capacity static ≤ 120 [N/mm2]
  • Specific load capacity dynamic ≤ 40 [N/mm2] at max. 2.0 m/s
  • Sliding speed ≤ 2.5 [m/s]
  • Friction value *** 0.05 [µ] to 0.12 [µ] depending on lubrication
  • Temperature strain – 40 [°C] to + 250 [°C]
  • Max. PV-value 2,8 [N/mm² x m/s]
  • Percentage contact area > 75 [%]

Tolerance Details

  • Housing Ø H7
  • Bushing inner-Ø after mounting H9
  • Shaft tolerancef 7 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 roundedThe application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.

Maintenance

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

Range of Application

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