insert bearing
radial rolling bearing with a spherical outside surface and an extended inner ring with a locking device
Note 1 to entry: The locking device, used for fixing the inner ring to the shaft, may be an eccentric locking collar or set screws either in a concentric locking collar around the inner ring or directly in the inner ring.
4 Symbols
ISO 8015 shall be applied and the dimensional and geometrical characteristics shall be included in the technical product documentation (for example, on the drawing). The dimensional specifications associated to these characteristics are described in Table 1.
In this document, the ISO default specification operator for size is in accordance with ISO 14405-1, i.e. the two-point size is valid. NOTE Figures 1 to 6 are drawn schematically and sealing devices and cages are not shown in Figures 1 to 4. A tolerance value and width of tolerance zone associated to a characteristic is symbolised by t followed by the symbol for the characteristic, for example t Vdsp or t A1.BS ISO 9628 pdf download.
