SNLN 30 plummer (pillow) block housings are split housings consisting of a cap and base. They have two holes cast into the base for attachment bolts. The housings are designed on the “building block” principle to enable a wider choice of bearings and seals as well as a variety of shaft-bearing combinations.
All SKF large-size housings are designed to provide excellent protection for the bearing and are equipped with a range of features that make them easy to install and maintain. They have a split design, which allows for easy access to the bearing for inspection, lubrication, and replacement. The housings also have a four-bolt mounting system, which provides a secure and stable connection to the foundation. SNL 30 series housing is designed to accommodate the following bearing series:
• 30(00) For housings from size 3024 to 3056, for bearings on an adapter sleeve
