89mm US Quality Approved Nylon Gym Cable Wheels & Plastic gym Rollers

  This is another item of nylon gym cable pulleys on strength machines , as we know well ,the function of this wheel is to work directing the power into different ways for reaching the strength works on the right position ,now so it is not working with only one or two wheels but five or six even more .

  Let's take one chest press machine for example , the movement needs the strength from your hands to the weight stacks , it finished up one when you find the weight plates up and down . first ,you push the poles with handles while the nylon cables which fixes with the steel on your arms connecting with handles come and go ,then the cables works on the wheels which direct into different ways till the weight plates . so the plates are lifted by the strength connecting cable and plates by a bolt .that is the way for any one-kind function strength machines .

  As any use by rollers ,we use it because it could reduce the weight pressure and help the thing to be finished by the direct function. now it works well on fitness equipment range.
