Internal Gear Ring

Product Overview

The internal gear ring, also known as an internal ring gear or inner gear ring, is an essential component widely used in planetary gearboxes, hydraulic drive systems, and industrial transmission assemblies. It features precision-machined internal teeth that seamlessly mesh with planetary gears, enabling efficient torque transmission and smooth rotational motion under demanding conditions.

Manufactured from high-grade alloy steel or carburizing steel, our internal gear rings undergo CNC gear hobbing, grinding, and heat treatment processes to ensure exceptional hardness, superior wear resistance, and a long service life. This product complies with international standards and is compatible with leading heavy-duty equipment brands.

Key Features
