Static misalignment

Y-bearings can accommodate initial misalignment by tilting in the housing (fig. 1), because of their sphered outside surface. The permissible values are:
  • SKF housings
    • relubrication is not required → 5°
    • relubrication is required (where applicable) → 2°
  • SKF pressed steel housings
    • Misalignment cannot be accommodated once the attachment bolts have been fully tightened, unless a rubber seating ring is used.

Dynamic misalignment

Y-bearings can accommodate a few minutes of arc (misalignment) between the inner and outer rings.
