CRC engineered this heavy‑duty formula to cling to exposed metal surfaces, absorb shock, and keep moving parts running quieter without constant reapplication. The 12 weight‑ounce aerosol delivers concentrated moly and graphite solids in a carrier that evaporates, leaving a durable, dark protective layer that resists displacement by water and surface contamination.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this lube protect open gears and chains under heavy loads?\u003c\/h3\u003e\n\u003cp\u003eThe molybdenum and graphite solids form a low‑friction, pressure‑resistant surface film that reduces metal‑to‑metal contact and dissipates impact forces.

CRC Extreme Duty Open Gear \u0026amp; Chain Lube is aimed at maintenance technicians, fleet operators, contractors and plant engineers who need a dependable, industrial‑grade lubricant for exposed mechanical components. If you maintain outdoor conveyors, mining equipment, construction machinery, winches, or open drive systems where water, grit and heavy loads threaten performance, this product provides a durable barrier of moly and graphite that reduces wear, noise and maintenance frequency.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this lube be used on sealed gearboxes?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. It's formulated for exposed gears and chains; sealed gearboxes require the manufacturer‑specified oil or grease.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is it safe for stainless steel and painted surfaces?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Safe for stainless steel lubrication; avoid contact with painted surfaces to prevent staining of the dark film.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"CRC","offers":[{"title":"Default Title","offer_id":48086042181790,"sku":"B000R8EI08","price":42.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/crc-aerosol-front-label.jpg?v=1785882716","url":"https:\/\/northtrailauto.ca\/products\/crc-extreme-duty-open-gear-chain-lube-12-oz-aerosol-with-moly-graphite-film-for-heavy-loads","provider":"North Trail Auto","version":"1.0","type":"link"}
