Each assembly includes the housing cap and base, cap bolts, bearing, bearing adapter, locknut and lockwasher, stabilizing ring and triple ring seals.
If only the pillow block is desired, use the numbers listed in column "Housing Only" column. These units include: cap, base, cap bolts, triple ring seals and stabilizing ring.
Assembly and pillow blocks as 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 23024).
Please note that for applications SAF23048 and larger, the shaft size must be included in the part description when ordering (e.g., SAF23048-8 15/16).

When ordering non-standard pillow block assemblies specify the shaft size.
