SAF and SAW pillow (plummer) block housings have appropriate positions for condition monitoring sensors. These housings provide a flat area to attach sensors for different condition monitoring equipment (fig. 1)
Position 1 is a measurement point perpendicular to the shaft, and should be used when the housing is hung from its support or when loads act away from the support surface.
Position 2 is a measurement point parallel to the shaft and should be used when loads act toward the support surface.
Both positions 1 and 2 are in accordance with ISO 10816-1:1995.
Position 3 is a measurement point that is approximately 20° to 45° to the shaft axis.
SAF and SAW housings have dimples cast into the housing cap to show where condition monitoring sensors can be mounted for maximum effectiveness.
