  • Each assembly includes the housing cap and base, cap bolts, bearing, locknut and washer, stabilizing ring and triple ring seals.
  • 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 23152).
  • For fixed applications, both stabilizing rings must be used. Do not use stabilizing rings for “Float” mounting.
