Cylindrical spur gears are the workhorses of parallel shaft transmissions, appreciated for their simple design, high efficiency, and lack of axial thrust loads. In heavy-duty drivetrains, keeping parallel shafts in alignment relies on gears with minimal pitch error and precise tooth spacing. Our robust cylindrical spur gear is engineered to provide reliable parallel power transmission under heavy radial loads. Over our 19 years in the gear manufacturing industry, we have worked closely with major industrial clients to refine our manufacturing processes. Backed by our parent company, Zhejiang Fengan Gear Co., Ltd., we operate a modern workshop equipped with advanced gear hobbing and profiling machinery, ensuring that every cylindrical spur gear matches your technical specifications.
We manufacture each cylindrical spur gear from high-grade alloy steel, using modern CNC hobbing machines and finishing equipment to ensure precise tooth spacing and profile accuracy. This high precision reduces gear whine at high speeds and ensures even wear across the gear face, extending the operating life of your gearboxes. We offer custom manufacturing based on your technical drawings, allowing you to specify module sizes, pressure angles, and bore configurations. We are committed to providing competitive factory-direct pricing, on-time deliveries, and comprehensive quality documentation for every shipment. |
