42×16T Flange Coupling Gear Hub Description

The YNF03427 42×16T Flange Coupling Gear Hub is a precision-machined transmission component designed for use in flange-type gear couplings. Gear hubs play a critical role in transmitting torque between rotating shafts while allowing slight misalignment and reducing vibration in mechanical drive systems.

Manufactured from high-strength steel, this gear hub features accurate tooth geometry and tight dimensional tolerance to ensure smooth engagement with the coupling sleeve. With an inner diameter range of 30–35 mm, outer diameter of 110 mm, and height of 55 mm, it is suitable for a wide range of industrial machinery, construction equipment, and power transmission systems.

The hardened and wear-resistant surface improves durability under continuous load and rotational stress, helping extend service life and minimize maintenance frequency. The YNF03427 gear hub is widely used by machinery repair workshops, equipment manufacturers, and aftermarket distributors as a reliable replacement coupling component.
