Large SNL series Plummer block housing SNL3144 SNL 3144 bearing block split plummer block housings SNL3144

SNL plummer block housings in the 30, 31 and 32 series are also referred to as “Large SNL plummer block housings”. These plummer block housings enable the bearings to achieve maximum bearing service life with less need for maintenance. This supports user 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. A range of seals for oil lubrication and difficult environments provide trouble-free operation.

SNL 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 graph-ite cast iron can be supplied. These housings are only available with four cast attachment bolt holes (series FSNLD) or without any holes in the base (series SSNLD).
