About Sandvik 552 146 98 PISTON
A critical hydraulic component in the Sandvik DI550 percussion mechanism, this piston converts hydraulic pressure into the powerful impact force needed for rock breaking. Located in the Inlet valve, 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 DI550 (DI550). 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
