• Mineral oil base with lithium / lithium-zinc soap thickener and MoS₂ solids
• Provides a robust EP-capable grease structure with solid-lubricant backup, delivering high load-carrying capacity and wear protection in highly loaded metal-to-metal contacts.
• High load-carrying capability
• Base oil viscosity around 105–106 mm²/s and MoS₂ solids support heavy unit loads in tie-rod ends, ball joints, and slow-speed bearings without film collapse.
• Wide service-temperature range (approx. −35 °C to 130 °C)
• Maintains lubricity and grease structure from cold starts through sustained hot running in chassis and machine joints.
• Resistance to oxidation and long-term lubrication
• Oxidation inhibitors slow grease degradation at temperature, supporting extended relubrication intervals in sealed or semi-sealed components.
• Good corrosion protection
• Corrosion inhibitors help protect steel surfaces in exposed linkages and bearings against rust in the presence of water and road or plant contamination.
• Good water resistance and washout performance
• Formulation resists water washout and maintains adhesion on exposed joints, which is critical in mobile equipment, on-highway trucks, and outdoor machinery.
• Compatible with many elastomers and plastics
• Listed as compatible with many elastomers and plastics, supporting use in assemblies where seals, boots, or polymer bearing cages are in contact with the grease.
• No intentional PTFE or PFAS
• Helps meet OEM and regulatory expectations about fluorinated substances while still delivering high load, long-life lubrication.
• NLGI Grade 2 consistency
• Offers a stable, pumpable grease body suitable for hand application, grease guns, and centralized lubrication systems.

Premature wear or play in chassis joints such as tie-rod ends, axle rod linkages, and ball joints that see high loads and oscillating motion; MOLYKOTE^® Longterm 2/78’s MoS₂-reinforced, high-viscosity film protects these metal-to-metal interfaces and helps maintain steering feel and alignment longer.
Frequent re-greasing and downtime on slow-speed, high-load bearings, guides, and splined shafts in mobile equipment and industrial machinery; the grease’s long-term lubrication, oxidation resistance, and water washout performance extend service intervals and reduce maintenance touchpoints.
• Corrosion and seizure of exposed linkage points in wet, dirty environments (road splash, wash bays, outdoor plant equipment); corrosion inhibitors and good water resistance help keep joints free-moving instead of rusted solid.
Inadequate film strength from generic multipurpose greases in heavily loaded small gear units and plain bearings running at slow speeds; Longterm 2/78’s high base oil viscosity and MoS₂ solids improve load capacity and mixed-friction performance in these low-speed, high-torque drives.
Concern over PFAS- or PTFE-containing greases in new designs; MOLYKOTE^® Longterm 2/78 is formulated with no intentional PTFE or PFAS, helping engineers specify a high-load MoS₂ chassis and bearing grease that is aligned with emerging material restrictions.
