Gear Ring

The Gear Ring (OEM 3217 3909 10) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. It carries rotational power between drive parts, meshing under load to provide controlled torque and speed for drilling and feed.

Made from case-hardened alloy steel with precision-cut teeth, it delivers smooth transmission, low backlash and strong resistance to wear and fatigue. As an alternative spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.

Backed by Delkom’s expertise in alternative rock drilling and drifter equipment, this part reflects the quality we export to over 100 countries. Reach out for availability, bulk pricing and technical support.
