Borelli bearing supports for group 1, 2 and 3 gear pumps.
The bearing support (belt-drive support) fits between the gear pump and the drive when the pump is driven by belt or chain, with heavy radial loads the pump cannot take on its own. The support bolts to the pump flange and connects to its shaft through a splined half coupling; the support bearing takes the pulley load.
The list shows the versions available, by pump group and shaft: group 1; group 2 with 18 or 22 mm shaft, 1:8 taper or Bosch 1:5 taper; group 3 in several versions (25.4 mm shaft, SAE B, 1:8 taper). Each option carries its Borelli code (25400 and 25600 series) and its datasheet is in the attachments.
According to the Borelli catalogue, life is 3,500 hours at 1,500 rpm and lubrication is with DIN 51502 MPF-1K-20 grease.
