As with the angled lock, the ends are less likely to hang in a coil or control port during linear movements.

Step cut/Type D (sharp corners)

Custom step cut piston ring + spring

In the radial direction, these ends must run completely along the radius of the cylinder wall and, thereby ensuring best possible sealing. This is an important technical aspect during production and is additionally checked. The correct lock clearance and lock length is important for proper operation when at operating temperature.

This type of lock is often used in compressors and start air valves in the shipping industry. Euroring produces this type of lock for tensioned piston rings both internally and externally.
