Load and bolt limit curves
If both radial and axial loads act upon the bearing, these need to be converted to a single equivalent load to enable accurate graphical analysis. Bearings should operate within the prescribed triangular load area at all times.
The bolt limit curve is based on the use of Grade 8.8 bolts. An improvement to this can be achieved by using Grade 10.9 bolts, but only after consultation with and approval of the NBC Technical Department.
If the load is suspended, or the axis of rotation is not vertical, refer the application details to NBC Technical Department by e-mail on email@example.com
Generally accepted interchange numbers are listed below. However, variations exist and all queries should be referred to our Technical Department for analysis.
Dimensional equivalence does not always imply equal performance!
