Graphite Lubricant for Bearings

The best lubricant for bearings depends on the operating environment. For high-temperature, heavy-load, or contamination-prone settings, dry graphite lubricants are ideal because they don't run, migrate, or attract particulates. For pneumatic or cold-weather applications, an extreme pressure lubricant like an anti-frost formula is more appropriate. Zircon Industries offers both options — consult our technical team at 800-547-4328 for a recommendation tailored to your specific bearing type and conditions.

AAR M971-93 is a certification issued by the Association of American Railroads that qualifies lubricants for use in railroad maintenance operations. It confirms the product meets stringent performance and safety standards required by North American rail operators. Zircon's Dry Graphite Lubricant is the only graphite product in their line to carry this approval, making it the required choice for CSX, Norfolk Southern, Canadian National, and Canadian Pacific contractors.

Zircon's Dry Graphite Lubricant is available in aerosol cans (20 oz, 12 per case) for precision or smaller-scale applications, and in bulk formats including 4x1 gallon cases, 5-gallon pails, and 55-gallon drums for large-scale industrial or railroad maintenance operations. Both formats deliver the same AAR-certified, quick-dry formula. Contact Zircon at 800-547-4328 for pricing and availability.

No. Zircon's Dry Graphite Lubricant uses a quick-dry carrier that evaporates rapidly after application, leaving only a dry graphite film on the surface. This means the lubricant stays exactly where it is applied and will not run, drip, or migrate to adjacent components — an important property for railroad switches, coupling components, and precision bearing surfaces.

Graphite lubricant is suitable for all metal-to-metal wear surfaces, including bearing assemblies, railroad switches, coupling components, autotrack equipment chains, tie-down chalks, hinges, thread lubricants, internal combustion engine components, and industrial gaskets. The dry graphite film provides lasting lubrication without attracting contaminants, making it versatile across railroad, manufacturing, automotive, and general industrial applications.

Dry graphite lubricant is generally applied to mechanical wear surfaces and is not recommended for live electrical components due to graphite's conductive properties. For pneumatic systems in cold weather, Zircon offers the Anti-Frost Pneumatic Tool Lubricant (X831 Chill Kill), a non-alcohol-based formula specifically designed to lubricate valves and ports without damaging pneumatic equipment.
