This lock type is mainly used to prevent the piston ring from springing open during installation. The preload creates too large a diameter that makes mounting difficult with recessed holes, blind installation and passing through ring grooves. This lock is therefore only used for outside tensioning piston rings.

Lock step cut / Type F

This lock can, if needed, be rotated by 90º to a radial configuration. We find this type of ring in turbochargers and gearboxes, which in turn can be found in:
