Standard housing design
SNL and SE plummer (pillow) block housings in the 2, 3, 5 and 6 series are split housings consisting of a cap and base (fig. 1 and fig. 2). 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.
SE plummer (pillow) block housings supersede SNL plummer (pillow) block housings for sizes 507 up to 515-612.
