Product Description

Internal Spur Gear for Planetary Transmission Systems

This internally toothed annulus gear features teeth aligned on the internal face of the ring, designed for planetary gear configurations. The internal tooth arrangement increases the contact surface area between mating gears, reducing load concentrations and significantly extending gear lifespan in high-ratio applications.
