STAR BRITE Wheel Bearing Grease NLGI #2 — Marine-Grade, Water-Resistant 3 oz. Cartridge with Grease Gun

STAR BRITE Wheel Bearing Grease is a marine-grade NLGI #2 lubricant formulated to protect trailer wheel bearings and other marine hardware from water, corrosion, and wear across a wide temperature range.

Whether you tow a boat, maintain a marina rig, or simply need a dependable grease for saltwater-exposed equipment, this product is engineered for harsh, wet environments. It meets ASTM D4950 GC-LB performance classifications and is produced in the USA, combining corrosion resistance with broad compatibility for many moving parts on boats, trailers, and outdoor equipment.

How does this grease defend bearings in saltwater conditions?

The formulation resists water washout and forms a protective film that helps prevent rust and electrolytic corrosion on bearing surfaces. It’s designed to remain in place under splashing and wet conditions typical of marine use, keeping lubricant where bearings need it most.

• Water-resistant base that minimizes washout
• Corrosion inhibitors to slow rust and pitting
• Stable film under repeated wet-dry cycles
• Maintains protection across variable saltwater exposures

What parts besides wheel bearings can benefit from this grease?

While optimized for trailer wheel bearings, this NLGI #2 formula is versatile enough for many marine and trailer components. Use it on winches, hatch hinges, pumps, anchor chain reels and other moving metal-to-metal contacts where water and salt are concerns.

• Winch gears and pawls — for smooth operation under load
• Hatch and door hinges — reduces squeak and wear
• Pumps and fittings — supports longevity in corrosive environments
• Anchor chain reels and swivels — shields against abrasion and corrosion

How easy is it to apply and maintain over time?

The product ships with a user-friendly grease gun and a 3 oz. cartridge for precise, one-handed application, which simplifies topping off bearings and hard-to-reach fittings. When the cartridge is consumed, compatible refills are available so you can continue regular maintenance without specialty tools.

• Comes with a lube gun and 3 oz. cartridge for controlled delivery
• One-handed operation speeds routine servicing
• Heavy-duty gun construction for repeated use
• Refill cartridges sold separately for straightforward replenishment

What performance range and standards does this grease meet?

This NLGI #2 grease is formulated to perform from low to high temperatures typical in marine and trailering applications. It satisfies ASTM D4950 GC-LB classification, signaling suitability for wheel bearing and chassis lubrication tasks while offering consistent protection under fluctuating conditions.

• Operational temperature range up to 325°F (0 to 325°F performance)
• Meets ASTM D4950 GC-LB industry classification
• Designed for extended service life in marine environments
• Balanced viscosity for bearing protection and ease of pumping

Who is this for? STAR BRITE Wheel Bearing Grease is intended for boat owners, trailer operators, marina maintenance crews, and outdoor gear technicians who need a dependable, marine-rated lubricant. If you service trailer hubs, winches, hinges, or any moving parts exposed to water and salt, this product offers a practical solution: easy application, refillable cartridges, and proven corrosion resistance from a US manufacturer trusted in marine care.
