About Sandvik 550 542 90 PISTON ROD D50
A critical hydraulic component in the Sandvik DX700 percussion mechanism, this piston converts hydraulic pressure into the powerful impact force needed for rock breaking. Located in the STEERING 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 DX700 (DX700). 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
How does a worn piston affect drilling performance?
