About Sandvik 550 990 58 Guide Ring, PISTON Rod
A critical hydraulic component in the Sandvik PANTERA DP1500i percussion mechanism, this piston converts hydraulic pressure into the powerful impact force needed for rock breaking. Located in the Cylinder Assembly, 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 PANTERA DP1500i (PANTERA DP1500i). 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
