SNL3060 SKF Split Plummer Block Housing for 280mm Shaft
Couldn't load pickup availability
The SKF SNL3060 is a cast iron split plummer block housing designed to support compatible spherical roller bearings and CARB toroidal roller bearings. Part of SKF’s SNL 30, 31 and 32 series, it provides a rigid bearing support for industrial machinery, while its removable housing cap simplifies bearing installation, inspection and maintenance.
The housing accommodates bearings with a 460 mm outside diameter and features a 168 mm bearing seat width and a 280 mm centre height. Its four-bolt base provides secure mounting, with elongated attachment holes allowing adjustment during installation.
When used with the bearing and adapter sleeve combinations listed below, the SNL3060 is suitable for a 280 mm shaft. Locating rings secure the bearing outer ring within the housing where axial location is required.
Designed for grease lubrication, the housing can be configured for through-shaft or shaft-end installations. Separate labyrinth and heavy-duty taconite seals allow the sealing arrangement to be selected for the operating environment.
