Theseshould be used if the housing cannot be mounted using the two centrally positioned fastening holes. Forexample, this can be the case when attaching to T profiles. The corresponding distances for the connectionsand the bore diameters can be found in the table on Page 26.Pin markings for additional dowel pinsSNC bearing housings can be fixed onto the mounting surface using additional dowel pins. To do this, drillholes at the four marking points for the dowel pins. Pinning is useful if extremely high loads will occurparallel to the mounting surface. The position of the holes in the support surface and the recommendeddowel pin diameters can be found in the table on Page 26.Mounting holesThe holes drilled on the underside of the housing foot simplify precise alignment of the units in seriesproduction. Dowel pins that have been pre-installed in the mounting surface as set out in the table on Page 26indicate the exact positions. If modification of the housing is necessary, the mounting holes can also beused for alignment on a processing machine with no problems.25
