  • timken-SAF-pillow-block-mounted-spherical-roller-bearing-unit-4-bolt-with-4-cap-bolts
  • Inch Tapered Bore Mounting Pillow Block SAF230K and SDAF230K Series
  • 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.
