OID / ENGINEERING TOOLS

Minimum load

Check whether the load is sufficient for stable rolling: by the general reference value or by execution data.

The specific bearing's data is entered manually.

01Method of check

Applies to all loads and load ratings in this form.

02Data for comparison

Optional. Must be of the same direction and régime as the minimum.

REFERENCE MATERIAL

How to determine the inputs

Open the explanation, pick the applicable table, or step through the worked example.

OID / REFERENCE DATA
Methodology and limits of applicability

OID, ch. 5, §5.3; table C

Pmin ≈ 0.01·C — ball
Pmin ≈ 0.02·C — roller

Input coefficients and requirements must correspond to the specific construction and duty. Missing values are never substituted automatically.

The life, static-safety and minimum-load checks are independent. Slewing bearings, linear systems, plain bearings and small oscillation angles need an applicable specialized model.

What limits this calculation:

  • minimum-load formulas of specific series and thrust executions — these usually depend on C₀a, speed and a series coefficient
