Pedestal loads

The maximum safe radial load for a pedestal casting is based on the bearing static rating C_or. The full C_or rating can be applied if the angle of the load falls within the shaded area of the sketch.

If the load falls outside the shaded area or is greater than C_or, please consult our technical department.

When considering suitability of pedestal castings, the resultant effective radial load must be used. The effective radial load is the resultant of net loads and appropriate dynamic factors, excluding speed and life factors.

If the axial load exceeds 50% of the axial rating (C_a), please consult our technical department.

For shock and pulsating loads, steel or ductile iron pedestals should be considered. For loads within 45° of the horizontal, the base should be chocked or dowelled, these modifications can be made upon request.

Flange load

The maximum load on cast iron flanges is 0.26 C_or or 0.25 C_a. Higher loads and shock conditions require ductile iron or steel flanges and high tensile bolts.
