108mm Commerical Quality Raw Metal Colour Alloy Material Gym Equipment Pulleys& Gym Wheels

  The dimension of pulleys in 89mm and 114mm are the most common in fitness equipment assemble ,though there are some diference in design with 105mm or any sizes else ,but it is not easy to find anyone could be used instead .

   The point of this specification is not only about the direction of working as ropes but also about the selling cost.  the alloy pulleys are origionally expensive than many plastic pulleys which are also exhensively used in equipment design . except the surface beauty of alloy material after oxidation and the colours could be very optional whatever you like just like the charcoal colour in the picture . this brings you much difference from nylon pulleys , you will be not good enough with black colour all the time .
