This was the first design of silver alloy pulleys used on strength machines 15years ago .that was really a amazing selling after that while continurous orders came perfectly.
Regards the shape , there is nothing special but without any holes in the middle of the pulley , this is not specification but also a different feeling , actually the pulley on gym equipment is to be assembled and covered by steel plates for both of the front and back sides .the bearing in the middle of the pulley will be running around the steel shaft which to be stable with the machine ,so all body of the pulley will be moving after the power from the movement of exercise . frankly ,there is no any difference with hole or not .it is not to be found anytime .
And the groove size of the pulley , seriously speaking ,it is better match the cable sizes exactly without shaking anytime ,but it doesn't make any sense because of the strength and straight direction . the common size of sides is 19mm to 21mm , somebody likes to use very thin cable by 5mm and there are also some buyers like to use thicker size more than 6mm . up to you .
