SNL Plummer Block Housings

SNL Plummer Block Housings are our most popular housings. Because of their versatility it is seldom necessary to resort to tailored housings for specific applications, minimising costs and production downtime. The housings are horizontally split and have two or four attachment bolt holes in the base as standard.
The basis of the SNL plummer block hous­ing system consists of a number of housings of the same design but in different sizes. By combining these housings with different stan­dard seals, a wide variety of housing variants can be supplied, all belonging to the standard range. SNL plummer blocks (up to size 32) can accommodate shaft diameters ranging from 20 to 160 mm making them a flexible solution.
The housing base of the SNL blocks is reinforced with ribs and extra material sur­rounding the holes for the attachment bolts in order to improve seating on the base plate. The attachment bolts can be preloaded to give better location and cannot deform the housing base or housing bore.
SNL housings have two attachment bolt holes in the base as standard. Cast indications show where to drill the additional holes to
make installation fast and simple. Indications are also given for holes to accommodate other components, such as dowel pins, sensors for condition monitoring, and addi­tional grease nipples.
SNL housings are supplied with a grease nipple; two tapped holes for the nipple in the cap are standard. Cast indications mark other grease nipple locations for re-lubrication of the bearing or the seals. Bearing life is also extended by the extra ribs in the housing base provide additional surface area between the base and base plate to improve heat flow away from the bearing.
Large SNL bearing housings are available for shaft diameters from 115 mm and above. The housings are horizontally split and have four attachment bolt holes in the base as standard. They have two eyebolts on the cap to facilitate handling.
