57 No: 4124851851.2.9007203379904011 en-US
11.1.3 Grease
Considering the high operating temperature in the rock drill gear housing, always use a
high-temperature grease with lithium complex soap based on a synthetic base fluid (polyal-
phaolefin/synthetic ester) with EP additive, and additives that protect against oxidation, cor-
rosion and wear at high loads. The grease should meet the specifications, specified in the
table below:
NLGI Number Drop Point Base Oil Viscosity Operating Temp
2 260 °C 220 cSt at 40 °C -15 to +150 °C
!
NOTE: Molybden (Molybden disulfide) grease is harmful for seals. Molybden grease
shall be avoided.
Epiroc recommends the use of Epiroc COP GREASE, which has been specially developed
for our hydraulic rock drills, and is suitable to be used in both gear housing and flushing
seals. COP Grease withstands temperatures between -40ºC to +150ºC, and temperatures
of up to 220ºC during shorter periods. COP Grease is developed to be implemented in
both arctic and tropical conditions, and can be ordered with the following part numbers:
Grease Tube 0.4 kg Can 18 kg
COP Grease 3115 3422 00 3115 3423 00
