SONL plummer (pillow) block housings must
be mounted properly using the appropriate
tools and state of the art mechanical mounting
methods. All the associated components must
also meet certain basic requirements (†
Specifications for shafts and housing support
surfaces on page 45).
Mounting instructions for each housing are
provided with the seal kit. For information J 6
about mounting rolling bearings, refer to the
SKF bearing maintenance handbook or

SONL plummer (pillow) block housings have
appropriate positions for condition monitoring
sensors († fig. 16).
Position 1 is a measurement point perpen-
dicular to the shaft and is in accordance with
ISO 10816-1.
Position 2 is a measurement point parallel
to the shaft and should be used when loads act
toward the support surface.
