NOTE: The catalog numbers in the above table with (F) on the end have both ends machined so that they can be butted against each other to make any desired length. The items with (D) have mounting screw holes for easier assembly.
CAUTION: SSR and SIR corner racks are external and internal ring gears. Perform secondary operations to suit your applications.
CAUTION: Precision grade standard of racks are set by KHK. Please see "Precision of Racks" in Selection Hints section for details.
