Shock Cushion Sub

Mass shock-cushion subs are utilized in conjunction with rotary or DTH drill strings to minimize shock and vibration damage to the rotary head, bit, and drill string components.

Benefits
1.    Reduces shocks and vibrations transmitted to the rotary head, thus safeguarding it from premature failures.
2.    The shock-cushion sub's floating piston feature protects the thread during making and breaking by allowing axial travel.
3.    Facilitates uniform pressure on the bit, thereby increasing bit lifespan and enabling faster penetration rates.
4.    The durable, maintenance-free design provides peace of mind without the need for worry for at least six months (the actual lifespan may be longer, depending on mine conditions).
5.    Optional safe lock feature eliminates the need for welding between the rotary head shaft and the shock sub and shock sub to the top adapter.
6.    Ensures smooth drilling operations by absorbing the majority of shocks and vibrations.
7.    Supports both angle and vertical drilling operations.
8.    Compatible with both rotary and DTH drilling applications.
