59mm Simplicity Dust Cap

59mm Simplicity dust cap is a replacement dust or grease cap.

The Simplicity dust cap fits all Simplicity bearing kits.

Specifications

OD: 59mm
Total Height: 35mm
Height Lip Insert: 7mm

Some hubs do not have machined chamfers in the boss and rear of the hub.

Inserting the 59mm dust cap can be difficult. Using a pipe of the correct diameter significantly improves how easily the dust cap can be installed.

Dust caps can become loose if you hammer them into position too often, even on the first insert.

Once the dust cap is home, stop hitting it. An extra hit can make it loose-fitting.

Question: Should I fill my grease cap full of grease?

Answer: No. The grease cap’s purpose is to catch excess grease when the bearing cavity is pressurised, which occurs during high-speed rotation.

Ideally, insert the grease cap dry. However, grease is generally oversupplied during the greasing process.

At high speeds and during initial heating and cooling, grease can exit the bearing cavity.

The 59mm Simplicity Dust Cap is designed to prevent grease from re-entering the bearing cavity once it is trapped inside. This technical explanation outlines how the product works and its role in maintaining optimal bearing performance.

Key Features

Preventative Design: The grease cap seals the bearing, ensuring trapped grease does not re-enter the bearing cavity. This is crucial for preventing contamination and maintaining bearing integrity.
Robust Materials: Made from durable materials, the dust cap withstands environmental factors while ensuring a secure fit over the bearing.
Easy Installation: The design allows quick, straightforward installation, so users can apply the dust cap without specialised tools.

How It Works

Sealing Mechanism: Once installed, the dust cap creates a tight seal around the bearing. This prevents external debris from entering while also keeping the grease contained.
Grease Retention: If any grease becomes trapped in the cap, it cannot return to the bearing cavity, ensuring the bearing remains free of excess grease that could cause performance issues.
Maintenance: Conduct regular checks to ensure the dust cap remains intact and functions as intended, helping prolong the bearing’s life.

Conclusion

The 59mm Simplicity Dust Cap plays a critical role in bearing maintenance by preventing grease from re-entering the bearing cavity. Understanding its technical specifications and functionality can help users make informed decisions about their trailer parts.

How to Install a Simplicity Dust Cap

Clean the hub surface: Make sure the mounting area is completely free of dirt, old grease, and debris before installing.
Align perfectly straight: Position the Simplicity dust cap squarely against the hub bore to prevent cross-threading or uneven seating.
Use a proper installation tool: Tap the cap gently into place using a dust cap installation tool or a soft-faced mallet (rubber or wood block) to distribute force evenly.
Seat it fully: Check that the dust cap flange sits completely flush against the face of the hub.

DO’s

Apply a light film of clean grease to the inner lip to ease installation.
Inspect the cap regularly for cracks, leaks, or loose fittings.
Ensure the internal rubber plug (if equipped) is intact and sealed tightly.

DON’Ts

DON’T use a steel claw hammer directly on the cap, as it will dent and ruin the seal.
DON’T over-fill the hub with grease, which can blow the cap off during travel.
DON’T reuse a severely warped or damaged dust cap.
