China Hot Sale Steel Hollow Shafts for Gearbox factory and manufacturers

Short Description:

Steel Flange Hollow Shafts for Gearbox Reducer

Our hollow shafts are mainly applied in gearbox motors, made of C45 steel and processed with tempering and quenching to enhance mechanical performance.

One outstanding merit of the hollow shaft design is its considerable weight-saving effect, which is beneficial to both structural engineering and practical function. The hollow center also improves space utilization, as it can serve as a passage for axles, drive components or other operating media.

Compared with solid shafts, the production of hollow shafts is more technically complicated. Its stability depends heavily on wall thickness, material selection, working load, torque, as well as overall dimensions including diameter and length.

Hollow shafts are critical elements in hollow-shaft motors for electric-driven vehicles like trains. They are also ideal for use in jigs, fixtures and automatic equipment manufacturing.

Our precision flange and hollow shafts are engineered for high-performance gearboxes, providing smooth torque transmission, high concentricity, and long service life. Made of high-strength alloy or stainless steel, these shafts are CNC machined to tight tolerances with corrosion-resistant surface finishes.

The flange design allows secure mounting, while the hollow structure reduces weight without losing strength. Suitable for automation, robotics, conveyors, and industrial machinery.

We offer customization on length, bore size, keyways, and surface finishes to meet specific requirements. The shafts fit standard gearbox setups and industry mounting standards.
