BRO-LUB®

Wrapped bronze sliding bearing - with filled lubrication pockets

Technical Details BRO-LUB®

  • Wrapped bronze sliding bearing
  • DIN 1494 / ISO 3547
  • Maintentance-free
  • Lubrication pockets filled with solid lubricant
BRO-LUB / BLZ

Properties

  • High load capacity at low abrasion, excellently suitable for low sliding speed and oscillating movements.

Materials

  • Support material CuSn8P (DIN 17662)
  • Lubrication pockets filled with solid lubricant

Material Properties

  • Specific load capacity static ≤ 120 [N/mm2]
  • Specific load capacity dynamic ≤ 40 [N/mm2]
  • Sliding speed ≤ 2.5 [m/s] depending on lubrication
  • Friction value *** 0.03 [µ] to 0.25 [µ] depending on lubrication
  • Temperature strain – 100 [°C] to + 200 [°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.
  • In spite of the bearing being maintenance-free, a primary lubrication is necessary.

Maintenance

  • BIV-LUB® is a maintenance-free composite sliding bearing with solid lubricant pockets, but primary lubrication is necessary. Therefore an aging resistant lithium stiffened grease should be used

Range of application

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