Trojan Bearing Boss Protector S/S 45mm

Trojan Bearing Boss Protector S/S 45mm is the stainless‑steel upgrade your trailer hub deserves. Replacing the standard grease cap, this protector turns your bearing housing into a sealed, grease‑charged sanctuary that stays lubricated longer and resists moisture ingress—even in challenging, damp environments.

• 45mm diameter, stainless steel construction—built to withstand road salt, moisture and grit while remaining durable over time.
• Replaces grease cap for a seamless, corrosion‑resistant seal that keeps bearings immersed in grease under slight pressure.
• Large grease capacity means fewer fill‑ups and more dependable lubrication between maintenance intervals.
• Prevents premature bearing failure by blocking moisture and keeping the bearing array thoroughly greased, even on rugged trailers.
• Easy, quick installation—designed for fast retrofits on Trojan hubs without special tools, so you can get back on the road sooner.
• Pair pack—two protectors come together to cover both ends of the axle for comprehensive protection.
• Suits Trojan 1500 kg hubs—optimized for common heavy‑duty trailer setups, providing reliable performance where it counts.

Ideal for campers, caravans, and light commercial trailers that face harsh weather, water spray, and dusty roads. The Trojan Bearing Boss Protector S/S 45mm turns a simple maintenance task into a durable, long‑term solution that keeps wheels turning smoothly—reducing downtime and extending hub life with proven, robust design.

Why choose this bearing protector

Rather than relying on a standard grease cap, you gain a purpose‑built reservoir and a seal that keeps lubrication in place while blocking contaminants. This design translates to longer bearing life, fewer grease top‑ups, and more predictable performance on long trips and demanding workdays. The Trojan name adds reassurance: built for reliability in demanding trailer applications, with components engineered to endure the tests of road use.

Practical care and use tips

Install as a direct replacement for your existing grease cap, then fill the system with grease as recommended for your Trojan 1500 kg hubs. Periodically inspect the seal area for wear and ensure the protector sits flush against the hub. When re-greasing, use the appropriate trailer bearing grease and follow your hub’s maintenance schedule to maximize efficiency and longevity.
