Mobilgrease XHP™ 320 Series — Lithium Complex Mine & Industrial Grease
Mobilgrease XHPâ„¢ 322
Super Premium Lithium Complex EP Grease | NLGI 2 | Mining & Heavy Industrial
Super Premium — Mine-Duty EP Performance
Mobilgrease XHP 322 is the NLGI 2 grade in ExxonMobil's super premium XHP 320 Series — a lithium complex EP grease engineered specifically for the most demanding mining and heavy industrial applications where shock loading, contamination, water exposure and high operating temperatures combine to defeat conventional EP greases.
The XHP 320 Series delivers superior performance across all key mining application parameters versus conventional lithium EP greases — higher dropping point (295°C), higher weld point (315 kg), better water washout resistance, better mechanical stability under shear, and superior oxidation resistance for extended relubrication intervals. Developed specifically for the severe operating conditions of open pit and underground mining equipment — conveyor systems, dragline pins and bushings, shovel components, crusher bearings and heavy mining support equipment.
Product Overview
Mobilgrease XHP™ 322 is a super premium NLGI 2 lithium complex EP grease formulated for demanding mining, quarrying and heavy industrial applications. The lithium complex thickener system delivers a dropping point of 295°C — well above the operating temperatures of mining equipment bearings — combined with excellent mechanical stability that resists softening under the high shear conditions of dragline pins, shovel crowd gears and heavily loaded conveyor bearings.
The EP additive package provides a four-ball weld point of 315 kg — protecting heavily loaded bearings, pins and bushings under the shock loading and sustained high loads typical of mining and quarrying operations. Outstanding resistance to water washout and water contamination maintains grease performance in wet underground mine environments and surface mining equipment exposed to dewatering spray and rain.
Available in 18 kg pail and 180 kg drum from Orbit Industrial — authorised Mobil sales agent, South Africa. Supplied to mining operations across the Northern Cape, Western Cape, Garden Route and Gauteng.
Performance Benefits
High Dropping Point — 295°C
295°C dropping point — the highest in its class — ensures the lithium complex thickener structure remains intact at the elevated temperatures of heavily loaded mining bearings, crusher bearings and electric motor bearings on continuous-duty mining equipment.
Extreme Pressure Protection — 315 kg Weld Point
Four-ball weld point of 315 kg provides outstanding EP protection for mining pins, bushings, dragline components and heavily loaded bearings under the shock loads and sustained heavy loading of open pit and underground mining operations.
Excellent Mechanical Stability
Outstanding resistance to mechanical degradation under shear — the grease maintains its NLGI 2 consistency under the continuous shear conditions of heavily loaded slow-speed bearings, dragline pins and bushed pivots, resisting the softening that causes grease leakage and bearing failure.
Water Washout Resistance
Excellent resistance to water washout and water contamination — maintaining grease film and bearing protection in underground mine environments and surface mining equipment exposed to dewatering spray, rain and high-pressure washdown.
Excellent Rust & Corrosion Protection
Outstanding rust and corrosion protection for bearing surfaces and housing components — protecting against the accelerated corrosion caused by mine water, acidic drainage and moisture ingress in underground and open pit mining environments.
Extended Relubrication Intervals
Superior oxidation resistance and grease retention enable extended relubrication intervals versus conventional lithium EP greases — reducing the frequency and cost of bearing relubrication on remote mining equipment where relubrication requires crew time and equipment shutdown.
Recommended Applications
Mining Equipment — Pins & Bushings
Dragline pins and bushings, shovel crowd gears and pins, excavator pin joints and pivots, crusher toggle pins and open pit mining support equipment — the primary applications where the XHP 322's combination of EP performance, mechanical stability and water resistance provides superior protection over conventional lithium EP greases.
Conveyor Systems
Mine conveyor idler bearings, conveyor drive gearbox bearings, take-up bearings and conveyor structure pivot points — where extended relubrication intervals, water resistance and EP performance reduce the maintenance burden on long conveyor systems in Northern Cape and Western Cape mining operations.
Heavy Industrial Equipment
Plain and rolling element bearings in quarrying, construction and heavy processing plant equipment — crushers, screens, vibrators and heavy machinery operating under combined heavy load, shock loading and water contamination where conventional lithium greases fail prematurely.
Electric Motor Bearings
Electric motor bearings on mining equipment — conveyors, fans, pumps and hoist motors — where the high dropping point, excellent mechanical stability and extended service life of XHP 322 provide superior bearing protection versus standard NLGI 2 lithium EP motor bearing greases.
