loads acting on a plummer block housing
are between 55° and 120° († fig. 2),
SKF ConCentra ball bearing units should be
doweled to the support surface or stops
should be provided in the direction of the
load. Recommendations for the position and
size of the dowel pin holes are provided in
table 2.
SKF ConCentra ball bearing units with
flanged housings have two or four drilled
holes to attach the housing to its support
surface. For applications where there are
heavy loads, SKF recommends doweling the
housing to its support surface. Dimples for
the dowel pin holes are cast into housings in
the SY, FY and FYTB series. Information on
the position and size of the holes for these
dowel pins is provided in table 3.
