The SKF SNL205 is a cast iron split plummer block housing designed to support compatible self-aligning ball bearings, spherical roller bearings and CARB toroidal roller bearings. Its rigid construction provides bearing support for industrial machinery, while the removable housing cap simplifies installation, inspection and maintenance.
The housing features a 52 mm bearing seat diameter, a 25 mm bearing seat width and a 40 mm centre height. Two elongated mounting holes, positioned at 130 mm centres, allow adjustment when securing the housing to its supporting surface.
Designed for grease lubrication, the SNL205 can be configured for through-shaft or shaft-end installations using suitable sealing accessories and an end cover. SKF lists labyrinth and heavy-duty taconite seal options, allowing the sealing arrangement to be selected for the operating environment.
The 52 mm dimension refers to the outside diameter of the bearing accommodated by the housing. The compatible bearings listed below have a 25 mm bore; the shaft dimensions at the seals must also suit the selected sealing arrangement.
