Inch Tapered Bore Mounting Pillow Block SDAF225 and SDAF226 Series
Mounted SAF Split-Block Spherical Roller Bearings
When ordering non-standard pillow block assemblies specify the shaft size.
- Each assembly includes the housing cap and base, cap bolts, bearing, bearing adapter, locknut and lockwasher, stabilizing ring and triple ring seals.
- To order pillow block housing only, use the number listed in the "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.
- Assemblies shown are furnished in cast iron. If cast steel is desired, add the letter "S" to the alpha prefix (e.g., SDAFS 22515).
When ordering non-standard pillow block assemblies specify the shaft size.
