Whitmore Industrial Grease Selection Guide: How to Match EP Grease to Mining and Heavy-Duty Applications

How to select Whitmore extreme pressure grease for mining and heavy-duty equipment is the exact question this episode answers — walking procurement managers and reliability engineers through every major product in the Whitmore EP grease lineup so your next RFQ matches the right thickener, base oil viscosity, and weld point to the actual application. Browse the full Whitmore catalog at https://www.pe-energy.com/brand/whitmore/ and hear all Whitmore episodes at https://www.pe-energy.com/podcast/whitmore/ Caliber 3M vs Caliber 5M for draglines and shovels. Both are lithium complex extreme pressure greases covering NLGI Arctic through EP 2, with a Four Ball EP weld point of 800 kg (minimum) and a wear scar of 0.50 mm on EP 0–EP 2 grades. The split: Caliber 3M carries 3% MoS2 on a straight lithium thickener; Caliber 5M carries 5% MoS2 on a lithium complex thickener for added oxidation stability. For cold climates, the Arctic grade pumps to -22°F (-30°C) at 400 psi on the Lincoln Ventmeter — spec it on Arctic mining rolling stock. https://www.pe-energy.com/product/whitmore-caliber-3m-arctic-greases/ and https://www.pe-energy.com/product/whitmore-caliber-5m-arctic-greases/ Caliber Blue EP and SL-Tech solid lubricants. When you need extreme pressure performance without MoS2 or graphite, Caliber Blue EP delivers a 620 kg weld point using Whitmore's proprietary SL-Tech solid lubricant blend — no heavy metals, no hazardous ingredients. Base oil viscosity is 760 cSt at 40°C; water spray-off loss is under 10% (ASTM D-4049), making it a strong fit for wet plant environments. Note: that high viscosity rules it out for electric motor bearings. Operating range is 18°F–200°F (-8°C to 95°C) for EP 1. https://www.pe-energy.com/product/caliber-blue-ep-2-2p-greases/ Caliber XR and XR-Syn for slew ring bearings and steel mills. At 1,000 cSt base oil viscosity (40°C), Caliber XR is Whitmore's most robust lithium-based bearing grease — built for steel mill roll stands, slew rings, and heavily loaded industrial mills. The mineral-base Caliber XR hits a 620 kg weld point and pumps to 25°F (-4°C). Upgrade to Caliber XR-Syn for an 800 kg weld point and cold pumpability to -40°F (-40°C) at 400 psi, with water washout loss of just 4% (ASTM D-1264). https://www.pe-energy.com/product/caliber-xr-ep-1-pail-greases/ Matrix EP calcium sulfonate grease for chemical and high-temperature environments. The calcium sulfonate complex thickener in Matrix EP neutralizes acids and has survived phosphoric acid fume exposure without corrosion. Continuous service to 400°F (200°C); sustains 550°F (288°C) with 30-minute relubrication intervals; tolerates 600°F (315°C) spikes for 5–10 minutes without carbonizing. Water spray-off under 1% (ASTM D-4049) — the tightest figure in this lineup. Meets Bucyrus International SD 4711 and DIN 51502 KP2R -20; approved by Andritz Separation for tilting pan filter auto-lube systems. https://www.pe-energy.com/product/matrix-ep-2-wliner-pail-greases/ Resources https://www.pe-energy.com/product/compass-ep-2-50-ct-cartridges-greases/ https://www.pe-energy.com/product/legacy-m-ep-1-50-ct-cartridg-greases/ https://www.pe-energy.com/product/medallion-fm-grease-2-kosher-cs-food-grade-lubricants/ https://www.pe-energy.com/product/multiplus-80w-90-pail-enclosed-gear-oils/ https://www.pe-energy.com/product/multiplus-85w-140-4x1-jug-cs-enclosed-gear-oils/ https://www.pe-energy.com/product/omnilith-gl-2-pail-greases/ https://gravatar.com/peenergymx https://gravatar.com/taylorindustrialequipment
