Where it is used
Components of this type are used across Cascade attachment lines including Carton Clamps, Bale Clamps, Rotators, Fork Positioners, Sideshifters, Hydraulic ReachForks and Push/Pull attachments. This is category-level context, not a fitment list — confirm the part number against your own attachment before ordering.
Service notes
Always fit a new locknut. A reused nylon-insert or prevailing-torque nut retains a fraction of its original locking force.
