Hollow Spline Shaft Drive Linear Bearing Shaft Hollow Connecting Tube Ball Spline Shaft

The main functions of hollow spline shaft include:

• Lightweight: Because the center section is hollow, hollow splined shafts are lighter than solid shafts, which is useful in applications where weight reduction is required to increase efficiency or reduce load.
• Stiffness: Despite being hollow, the splined shaft is designed to provide sufficient stiffness to withstand torque and prevent bending.
• Transmitting Power: Spline grooves allow mating with keys to transmit power to other mechanical components, such as gears or couplings.
• Space Savings: In some designs, hollow splined shafts can be used to transport oil, gas, or other media through the interior of the shaft, saving space and reducing complexity.

Hollow spline shafts are widely used in various machinery and equipment, especially where light weight, high stiffness and the ability to transmit power are required.

Our company was formerly known as Changsha Double Star Gear Industrial Co., Ltd, which was established in 1994. It is a directly affiliated university-run enterprise founded by Central South University Professor Zeng Tao, the leading expert on spiral bevel gears in China. It was later renamed as Changsha Senjie Gear Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production R&D base specializing in professional design, reserch, manufacture and sales of high-quality small module spiral bevel gears and high reduction hypoid gears and cylindrical gears. In 2023, Hunan Dinghan New Material Technology Co., Ltd. was established as a specialized international export business department. CSG has strong scientific research and development capabilities and is also equipped a full set of advanced equipment including seven-axis five-linkage CNC spiral bevel gear grinding machines and gear milling machines. By making the best use of the scientific and technological achievements and equipment of the Gear Research Institute of Central South University, machanical processing, heat treatment and testing. We have developed high-quality products featuring high reduction, high speed, heavy load, low noise and less teeth for users.

With the quality policy of "scientific and technological innovation, quality first, being first-class firm and customer‘s satisfaction", we have won the trust of well-known domestic and abroad enterprises with stable and excellent quality. It is committed to be a pioneer of the industry of China's small-module spiral bevel gears, and is dedicated to providing service for any related industry requiring industrial robots, CNC turning and milling compound power tool turrets, industrial sewing machines, reducers, bicycles, power tools and aeromodelling. We sincerely look forward to your cooperation!
