SKF Pillow block housing SSNLD 520-617

SNL and SE plummer (pillow) block housings in the 2, 3, 5 and 6 series are the most popular SKF bearing housings on the market. Different housing variants and seal designs are available, making the use of tailored housings virtually unnecessary and enabling costeffective bearing arrangements to be made.
The plummer block housings are split housings and as standard they have two holes cast into the base for attachment bolts. The plummer block housings can als be supplied in a four cast bolt hole configuration. These housings are designated with a prefix F.

The split plummer block housings are typically used with self-aligning ball bearings, spherical roller bearings or CARB toroidal roller bearings fitted on straight or stepped shafts; the bearings can be mounted on adapter or withdrawal sleeves or directly on cylindrical shaft seats.

The plummer block housings are made of high quality, grey cast iron to provide high tensile strength. For applications where additional strength is required, housings made of spheroidal graphite cast iron are available. These types of housings are supplied with a solid base (no holes for attachment bolts) as standard (type SSNLD or SSED).
