The nominal diameter of the supported-end refers to the nominal diameter opposite to the fixed-end; the inner diameter of the supported end is equal to or smaller than nominal diameter.
☐ : Bearing type. Blank refers to standard production which uses a 30 degree angular contact bearing. On shaft diameter over 20mm, a 40 degree angular contact bearing is available. Nominal diameter of 35mm and 40 mm require higher radial loading and are only offered with the 40 degree angular contact bearing.
