  • Each assembly includes the housing cap and base, cap bolts, bearing, locknut and lockwasher, stabilizing ring and triple ring seals.
  • To order pillow block housing only, use the numbers listed in "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., SAFS 22217).

Speed ratings are found in dimension tables in the spherical roller bearing section.
