Trojan 45mm Grease Cap Pair – Hub Sealing Components for Agricultural & Industrial Lubrication Equipment

Preserve bearing longevity and maintain pressure seals during regreasing cycles with precision-fitted 45mm grease caps engineered for rapid field service.

Precision Dimensional Fitment

Manufactured to exact 45mm outer diameter tolerances, this cap pair aligns directly with standard wheel hub bosses and bearing housings found across tractors, trailers, pumps, and conveyors. The threaded retention design screws securely onto pre-tapped hub surfaces, providing quick removal and reinstall without damaging threads or shifting internal bearing positions.

Field-Durable Construction

Constructed from hardened steel with a corrosion-resistant surface treatment, each cap resists oxidation from moisture, fertilizer runoff, and salt exposure. The paired quantity enables balanced replacement across dual-wheel axles or complete retrofit projects, ensuring uniform clearance and load distribution when protecting packed grease zones from abrasive particulate ingress.

• 45mm diameter matches common hub configurations for immediate drop-in compatibility
• Threaded attachment system prevents vibration-induced loosening under heavy torque loads
• Maintains full access to zerk fittings without requiring shaft extraction or hub disassembly
• Corrosion-resistant exterior finish withstands harsh agricultural and marine-grade environments
• Matching left-right sizing delivers symmetric sealing profile for complete axle restoration

Replacing worn or stripped caps restores factory-level bearing isolation and keeps lubrication points reachable during scheduled maintenance. These Trojan grease caps eliminate the gap-and-leak cycle that accelerates inner race wear, extending interval performance while reducing unscheduled downtime on high-use mechanical systems.
