Segment Gears

Spur Gears Manufacturing

Our segment gears are specialized partial‑circle gears designed to transmit motion and torque over a limited arc rather than a full 360‑degree rotation. This makes them ideal for heavy industrial machines that require controlled, intermittent, or reciprocating movement. In quarry crushers, cement plants, and large material‑handling systems, segment gears are often used to drive massive components where a full gear would be unnecessary, too heavy, or difficult to install. Their segmented design allows engineers to achieve precise motion control while reducing overall material usage and simplifying maintenance.

Because segment gears are manufactured in sections, they offer major advantages in serviceability and cost efficiency. Instead of replacing an entire large gear, technicians can remove and install only the worn segments, dramatically reducing downtime. At Mass Gear, segment gears are produced using high‑strength alloys, precision machining, and robust heat‑treatment processes to ensure durability under shock loads, dust, and continuous operation—conditions common in quarries and heavy industries. Their modular construction, combined with accurate tooth profiles, ensures smooth engagement, long service life, and reliable performance even in the harshest working environments.
