Crankshaft Seal

Description

Intended for professional drill rig and drifter maintenance, the Crankshaft Seal (OEM 4R-9999) is engineered to fit the service requirements of the rock drilling machine or hydraulic drifter assembly. It forms a controlled barrier between mating surfaces, helping prevent fluid loss and ingress of abrasive contaminants.

Controlled sealing dimensions help preserve contact at the mating surface while resisting wear, contamination and repeated cycling. Designed for aftermarket use, it helps maintenance teams control spare-parts cost while keeping the correct application and cross-reference clearly identified.

Delkom combines rock-drilling spare-parts expertise with international supply capability, serving mining and tunneling customers across more than 100 countries.
