To order pillow block housing only, use the numbers listed in the "Housing Only" column. These units include: cap, base, cap bolts, triple ring seals and stabilizing ring.
Assembly and pillow blocks described on this page constitute fixed units.
To order float units, specify part number plus suffix "Float" or "FL".
If one end closed assembly is required, specify “CL” in assembly number when ordering.
All assemblies shown are furnished in cast iron. If cast steel is desired, add the letter "S" to the alpha prefix (e.g., SDAFS 22220).
