UKI SNA series horizontally split Plummer Blocks (bearing housings) is completely interchangeable with earlier SN type Plummer Blocks, concerning mainly to its center height, foundation bolt centres. Same bearing housings can be used for 500 and 600 series bearings having equal bearing outside diameter by changing its shaft seal, eg. SNA 506 plummer blocks can be used as SNA 605 also where bearing O.D of 1206 K and 1305 K are equal, eg. 52 mm
Similarly same plummer blocks can be used for bearing with tapered bore mounted with adapter sleeve or bearing with (straight) cylindrical bore. However such plummer blocks are designated as SNA 500 and SNA 600 for bearings with adapter sleeves and SNA 200 & SNA 300 for bearings with cylindrical bores. Bearings seating width provides axial freedom which can be made axially located by insertion of suitable locating rings. SNA series are primarily designed for bearings mounted directly on cylindrical shafts or on adapter sleeves. Their design is based on a building block principle. This provides different options for the selection of bearings and methods of mounting as well as choice of seals, metric and inch, and forms of lubrication and monitoring systems.
