  • The basic number for ordering complete pillow block assemblies is listed in the table below.
  • 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 housing is desired, use the numbers listed in column headed "Housing Only". These units include: cap, base, cap bolts, triple ring seals and stabilizing ring.
  • All assemblies and housings described on this page constitute fixed open units (FXOP), which are typically stocked items. To create the float open (FLOP) version, order the FXOP version and remove the stabilizing ring from the housing.
  • If a closed end housing is required, order the FXOP version and order the appropriate end plug separately to create the fixed closed (FXCL) or float closed (FLCL) versions (remove stabilizing ring for FLCL).
  • In some cases FXCL, FLCL, and FLOP units are stocked, contact Timken Customer Service for details.
  • Assemblies shown are furnished in cast iron. If cast steel is desired, add the letter "S" to the alpha prefix (e.g., SAFS 22515K).
