Product Description

Our Heavy-Duty Sector Spur Gear is designed for high-load industrial transmission systems requiring precise rotary positioning, intermittent motion, and reliable torque transfer. Unlike a full circular gear, the sector gear provides efficient power transmission over a limited rotation angle, making it an ideal solution for large machinery where full-rotation gears are unnecessary.

Manufactured from premium-grade steel and precision-machined using advanced CNC equipment, every sector gear is produced according to customer drawings and technical specifications to ensure exceptional accuracy, strength, and durability.

Product Features

Precision Spur Gear Teeth

The external spur teeth are machined with high accuracy to provide smooth meshing, consistent transmission, and reduced vibration during operation.

Reinforced Lightweight Structure

The optimized spoke-type body reduces overall weight while maintaining excellent rigidity and structural stability, making the gear suitable for large-diameter applications.

High Torque Capacity

Designed for demanding industrial environments, the gear withstands heavy loads, impact forces, and continuous operating conditions.

Excellent Dimensional Accuracy

Critical surfaces, including the bore, mounting faces, tooth profile, and locating features, are precision-machined to simplify installation and improve transmission performance.

Long Service Life

High-quality materials combined with appropriate heat treatment deliver excellent wear resistance, fatigue strength, and long-term operational reliability.
