Power springs are widely used in fitness equipment, such as a seated row machine or an abdominal roller wheel. The most commonly used materials for the power springs are 62Si2MnA, BTX(1078) carbon steel and SK5 carbon steel. After the heat treatment, the rigidity is in a range of HV480 to 510, the tension strength reaches up to 1700-3500kgf/mm², and the maximum service life is 50,000 usages. With over 25 years of experience, Zongda has the capability to produce power springs for fitness equipment with a thickness range of 0.65mm to 1.2mm, width range from 6mm to 30mm, and length from 1500mm to 4000mm. We can also customize the power springs, as long as customers provide information regarding what material they want to use, spring size, and power spring application. The following products are spring examples for fitness AB rollers and row machines. We keep a number of products in stock, as well as carry out custom order production.

Power springs play an important role in row machines. Compared to a hydraulic seated row machine, power springs ensure the cable row runs with a uniform force, and reduces the risk of muscular injury. The power spring in the cable row machine is wound in the opposite direction, and supports a cable of 2 to 3 meters in length. We just the power spring force through a heat treatment of the spring strips. When using a row machine with power springs, customers experience a more comfortable pulling performance that is smoother and safer. We are a trusted power spring manufacturer, and offer customization services.

Abdominal exercise is easily done either at home or at the gym using an abdominal exercise roller wheel. Compared to an AB carver roll that uses wire springs, the power spring roller features lower noise levels, and when used correctly, assists users in obtaining an excellent abdominal shaping effect. The automatic rebound AB roller uses rewinding spring strips to ensure the force remains within a specific space, and allows users to easily push and pull the roller to carry out exercise. The roller springs are heat treated in order to increase elasticity, which ensures exercise is safe, and will obtain outstanding results. We can customize the power springs based on roller specifications.
