The SNL 30, 31, 32 series Split Plummer Block Housings, also referred to as "Large SNL Split Plummer Block Housings", enable the bearings to achieve maximum bearing service life with minimum need for maintenance. 

This supports users' efforts to further reduce maintenance costs. Among other enhancements, SNL housings are designed for easy alignment and handling during installation. Another benefit is the choice of oil or grease lubrication for the bearings housed in SNL plummer blocks.

SNL housings can be used for both the locating and non-locating bearing positions. In addition to the standard seal assortment. SNL housings in the 30, 31 and 32 series are also available with seals for large axial movements. Custom seals for special applications are also available on request.

The SNL split plummer block housings are made of grey cast iron. For applications where the strength of grey cast iron is inadequate, dimensionally equivalent housings made of spheroidal graphite cast iron (Ductile Iron) or cast steel can also be supplied. These series bearing housings are only available with four cast attachment bolt holes (series FSNLD) or without any holes in the base (series SSNLD).
