KAJO MHP Rock Breaker Grease: Choosing the Right Cartridge for Your Hydraulic Hammer
on Sep 24 2026
Hydraulic rock breakers operate in some of the toughest working conditions across construction, mining, quarrying and demolition. High impact loads, vibration, heat, dust and moisture place significant demands on the hydraulic hammer, insertion tool, and wear components.
KAJO®-Grease MHP, developed and manufactured by KAJO in Germany, is specifically formulated for the demanding lubrication requirements of hydraulic hammers.
But choosing the right hammer grease isn't only about the grease itself, especially on hammers over the 12t sizes where there is an auto grease pump system.
To support different hammer and automatic lubrication systems, KAJO Australia offers the MHP Rock Breaker Grease range in three different cartridges:
KAJO MHP ROCK BREAKER GREASE – 500g Small Thread
KAJO MHP ROCK BREAKER GREASE - 500g (Ø22mm Large Thread)
KAJO MHP ROCK BREAKER GREASE - 400g (Ø22mm Large Thread)
Why Rock Breakers Need a Specialised Grease
Hydraulic hammers and rock breakers have very different lubrication demands from standard bearing or general-purpose grease applications.
A hydraulic hammer/rock breaker generates repeated high-impact forces to break rock, concrete and other hard materials. This creates a particularly demanding lubrication point between the socket end of the chisel and the guiding sleeve.
KAJO identifies this area as the critical wear point within the hammer. Using a purpose-designed grease helps provide a protective lubricating and separating layer between these heavily loaded components, assisting in reducing wear and protecting the equipment during operation.
KAJO®-Grease MHP has been developed specifically for hydraulic and pneumatic hammer applications, offering:
High pressure absorption
Wear reduction
Water resistance
Corrosion protection
Oxidation resistance
Engineered for Extreme Loads
KAJO®-Grease MHP has been specifically formulated for applications involving substantial surface pressures.
Its formulation is based on mineral oil with a lithium soap thickener and incorporates a combination of 30% solid lubricants including:
Copper
Graphite
Molybdenum disulfide (MoS₂)
These solid lubricants contribute to the grease separation properties and wear protection under high surface pressures and elevated temperatures. KAJO's technical data sheet specifies an operating temperature range of -20°C to +1100°C.
The product is an NLGI Grade 2 lubricant and records an OK load of 4,000 N and weld load of 4,200 N under the four-ball test detailed in the KAJO technical data sheet.
For demanding hydraulic hammer / rock breaker applications, these characteristics are particularly important where conventional lubricating greases may not be designed for the combination of impact, pressure and temperature experienced around the chisel.
KAJO MHP Cartridge Options for Different Rock Breakers
The key difference is the cartridge size and thread which must suit the rock breaker and lubrication system being used.
All three cartridge options contain KAJO®-Grease MHP, a specialist grease developed for hydraulic and pneumatic hammers.
