Standard housing design
SE plummer (pillow) block housings in the 2, 3, 5 and 6 series are split housings consisting of a cap and base (fig. 1). They have two holes cast into the base for attachment bolts.
The housings are designed on the “building block” principle to enable a wider choice of bearings and seals as well as a variety of shaft-bearing combinations and lubrication methods.
