MOBILITH SHC 220 (16KG): Ideal Mobil Grease for McCloskey Mining Crushers
>>Download full datasheet<<
Core Performance Attributes
MOBILITH SHC 220 is a super-premium synthetic grease built on a Lithium Complex thickener system and Polyalphaolefin (PAO) base fluid. This chemical foundation delivers performance attributes that are unobtainable with conventional mineral-based lubricants.
Extreme Load Defense (EP Protection)
The high-pressure capability is non-negotiable for bearing applications where shock loads are routine. The lubricant achieves a remarkable 4-Ball Weld Load of 250 Kg. This high Extreme Pressure (EP) rating signifies that the grease additive package and base oil maintain a robust lubricating film under tremendous instantaneous pressure, protecting bearing rolling elements and races from metal-to-metal contact and indentation caused by heavy vibration and impact loading. Reduced wear under heavy loads is a key benefit derived from this EP characteristic.
Low Coefficient of Traction: Energy Savings and Cooler Running
-
Reduced Energy Consumption: Less power is dissipated as heat within the lubricant, leading to improved mechanical efficiency and potential energy savings in high-throughput applications.
-
Cooler Operation: Lower internal friction inherently results in lower operating temperatures within the load zone of rolling element bearings. Cooler operation directly slows the thermal degradation of both the lubricant and the bearing components, drastically extending service life.
Viscosity Index Stability across Temperature Extremes
The inherent viscosity index (VI) of the synthetic base oil (VI is 179 for this grade series) is far superior to mineral oils. This high VI signifies that the base oil's viscosity changes less dramatically across the grease’s massive operating temperature range of -40°C to 180°C. This stability ensures that the necessary lubricating film thickness (ISO VG 220 at 40°C) is maintained under peak operational heat, preventing shear thinning and potential boundary lubrication failure. Simultaneously, it guarantees that the grease remains flowable and pumpable in low temperatures, preventing bearing starvation at cold startup.

The McCloskey Crusher Imperative
McCloskey crushers—whether jaw, cone, or impact models—operate in an environment that pushes standard mineral greases beyond their performance limits. Critical bearings and articulation points are subjected to severe cyclical and non-cyclical loads, intense localized frictional heat, and persistent contamination from dust and water. The lubrication system in these assets is frequently listed in operator manuals as a key fault point, with warnings triggered for "greaser malfunctions" and lubrication issues potentially leading to immediate crusher shutdown.
MOBILITH SHC 220 is formulated to provide an exceptional margin of safety against these inherent operational risks. The lubricant’s suitability is ideal for use in McCloskey Crushers. This assurance eliminates specification risk for maintenance engineers seeking guaranteed performance in their high-capital equipment. By choosing this solution, operators invest in minimizing unplanned downtime and maximizing the operational life of highly stressed components.
Commercial Strategy and Total Cost of Ownership (TCO)
The selection of a premium synthetic lubricant like MOBILITH SHC 220 is justified commercially through a clear demonstration of reduced TCO, especially when the initial procurement cost is higher than conventional alternatives.
The financial justification for this investment is realized through three core mechanisms that minimize operational expense:
-
Maximized Uptime: The primary cost driver in mining is unscheduled downtime. Given that McCloskey crushers process high volumes of material, an hour of lost production due to bearing failure (a failure often accelerated by mineral grease breakdown) can cost orders of magnitude more than the lubricant itself. By providing superior protection against heat, shock, and contamination, SHC 220 serves as an insurance policy, extending bearing life and assuring continuous operation.
-
Extended Relubrication Intervals: The thermal and oxidation stability of the synthetic PAO base oil is significantly superior to mineral oils. This means the grease maintains its integrity and viscosity for much longer periods, allowing for extended intervals between relubrication. This dramatically reduces maintenance labor hours, minimizes the volume of grease consumed annually, and lowers disposal costs.
-
Energy Efficiency: The low coefficient of traction of the PAO oil translates into tangible, though difficult to precisely measure, reductions in energy consumption by minimizing frictional drag within the bearing. Over the lifetime of a high-power crusher, these incremental energy savings contribute significantly to the TCO reduction.
The purchase decision for MOBILITH SHC 220 shifts from a pure procurement cost analysis to a long-term asset reliability strategy.
OEM Maintenance Integration Recommendations
Integrating MOBILITH SHC 220 into a McCloskey maintenance program requires adherence to OEM specifications while optimizing the benefits of the synthetic product.
Standardized Lubrication Schedule
While the SHC grease permits extended relubrication intervals due to its low volatility and extended service life , it remains essential that operators continue to perform checks and follow the fundamental lubrication schedule outlined in the crusher's Operator's and Maintenance Manual. Attention must be paid to distinct lubrication systems within the crusher, such as the pinion shaft lubrication, which typically requires a separate oil change coinciding with cone crusher lubrication oil changes. Ensuring the correct fluid levels and volumes are respected is non-negotiable, irrespective of the superior quality of the lubricant used.
Inventory Consolidation Opportunity
Facilities utilizing synthetic greases in critical high-temperature or high-load applications, such as crushers, have the strategic opportunity to extend the use of these superior products to include many normal-duty applications across the site. This standardization, centered around a high-performance product like MOBILITH SHC 220, significantly reduces the number of unique lubricants that must be stocked. The reduction in lubricant inventory simplifies stocking, reduces procurement costs, and minimizes the risk of human error where the wrong grease is applied to a machine—a frequent cause of premature failure in complex industrial settings. This strategic deployment maximizes the return on the initial investment in premium synthetic technology.
