TFI Traveling Blocks
  
 

TFI traveling blocks are designed and manufactured according to API Spec 8C specification. Sheave grooves are hardened by medium frequency induction quenching to maximize service life. Double row roller bearings and alloy steel shafts ensure operational strength. Sheaves and bearings are interchangeable with American counterparts.
