Category overview
Rotary head and rotation unit parts for Epiroc drilling and exploration equipment
The rotary head is the primary torque delivery system on every Epiroc drill — it drives the drill string, controls rotation speed, and takes continuous stress on every metre drilled. When a hydraulic motor fails, a bearing wears out, or seals start leaking, rotation stops and so does the hole. eincors carries rotary units, rotation units, hydraulic motors, gear wheels, chuck housings, swivels, bearings, seal kits, oil seals, and all associated service components for Epiroc blasthole drills, surface rigs, underground face drills, and exploration rigs — organized by machine model for fast identification.
Coverage scope
Rotary units, rotation units, hydraulic motors, gear wheels, output gears, chuck housings, swivel assemblies, roller bearings, ball bearings, seal kits, oil seals, axial seals, radial lip seals, bushings, wear sleeves, housings, gear output components, signal cables, and lubrication components — covering Pit Viper, DM series, DIAMEC, Explorac, Boomer, SmartROC, ROC, PowerROC, and Boltec models.

Atlas Copco ↔ Epiroc cross-reference
Epiroc’s drilling and mining equipment division operated under Atlas Copco until 2018. Rotary head and rotation unit part numbers in older service manuals may still carry Atlas Copco references. eincors cross-references both — send the number you have and we’ll match it to the current Epiroc equivalent.
Frequently asked questions
What rotary head and rotation unit parts does eincors carry for Epiroc rigs?
We carry 950+ parts covering rotary units, rotation units, hydraulic motors, gear wheels, output gears, chuck housings, swivel assemblies, roller bearings, ball bearings, seal kits, oil seals, axial seals, bushings, wear sleeves, housings, and all associated service hardware — across Pit Viper, DM series, DIAMEC, Explorac, Boomer, SmartROC, ROC, PowerROC, Boltec, and Cabletec models.
Do you carry rotary head parts for DIAMEC exploration drilling rigs?
Yes. DIAMEC Diamond Core Drill and DIAMEC U6 PHC are among the highest-coverage models in our rotary head catalog, with combined references covering hydraulic motors, gear wheels, seals, bearings, swivels, and associated service components.
Can you cross-reference Atlas Copco rotary head part numbers?
Yes. Many Epiroc rigs were built and documented under Atlas Copco before the 2018 spin-off, and rotary head part numbers in older service books may still carry Atlas Copco references. Send us what you have and we’ll find the current equivalent.
