The diagram illustrates a "01 family" bearing with location diameters on inner and outer ring (Generic part ref. SUN xxx 20 01 CC LM). Note: the "00 family" does not exhibit these toleranced diameters.
Final part number dependent on bearing specification e.g. SUN 486 20 51 CC LM
Bearings usually manufactured in C45 steel (Europe) or 50Mn (China), roughly equivalent to BS 080M46
Bearings usually supplied with 4 grease points in the outer ring only, DIN 71412A M8x1 equispaced
Load and bolt limit curves
Bearings should operate within the prescribed triangular load area at all times. If a combination radial and axial load act on the bearing this should be replaced by a single equivalent load for graphical analysis.
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 approval of the NBC Technical Department.
If the load is suspended, or the axis of rotation is not vertical, refer application details to slewingrings@nbcgroup.co.uk
Units: Y-Axis = moment load in KN.m; X-Axis = Axial load in KN
Interchange information
This information offers generally accepted interchange numbers. However, variations exist and all queries should be referred to our Technical Department for analysis. Dimensional equivalence does not always imply equal performance!
