About Sandvik 887 078 49 PISTON RING
A critical hydraulic component in the Sandvik AXERA 7-240 percussion mechanism, this piston converts hydraulic pressure into the powerful impact force needed for rock breaking. Located in the GEARBOX CONVERTER, 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 AXERA 7-240 (AXERA 7-240). Also compatible with Tamrock branded equipment of the same model series. BK Drilling supplies this part with fast worldwide shipping and competitive pricing.
