Pivot and Axle Structure of the Round Fan: Precision at the Heart of Smooth Opening

Although a round fan doesn't open and close as often as a folding fan, the connecting pivot between handle and face, and the rotating axle of a rotatable round fan, directly affect handling feel and service life. Material selection, assembly, and anti-loosening are all essential.

The Scenario: Three challenges in pivot design

Round-fan pivot and axle design has three challenges:

Pain Points

• Axle material that doesn't match fan-rib hardness wears and loosens over long rotation;
• Improper assembly clearance makes the axle bind when tight or wobble when loose;
• Humidity can rust or swell the axle, hurting smooth opening.

The Solution: Three pivot-craft points

Round-fan pivot and axle craft has three points:

1. Axle material and hardness match Choose brass, stainless steel, or hardwood axles to match rib material, with matched hardness and wear resistance.

2. Clearance and lubrication control Precisely control axle-hole clearance with light lubrication for smooth, non-loose rotation.

3. Anti-loosen and anti-rust Secure axle ends and apply anti-rust treatment to withstand humidity and long use.

The Result: Smooth opening, lasting durability

With pivot craft in place, the round fan opens smoothly and rotates freely, staying tight through long use — for both collection and daily use.
