About Sandvik 550 390 50 Rod, PISTON
A critical hydraulic component in the Sandvik DD320S percussion mechanism, this piston converts hydraulic pressure into the powerful impact force needed for rock breaking. Located in the Cylinder, worn pistons cause reduced penetration rate, increased energy consumption, and decreased overall drilling efficiency.
This is an OEM-compatible aftermarket replacement part for the Sandvik DD320S (DD320S). Also compatible with Tamrock branded equipment of the same model series. BK Drilling supplies this part with fast worldwide shipping and competitive pricing.
Frequently asked questions
