The roller that moves the center shaft with the heavy object is called a moving roller. It is a deformed unequal arm lever, which can save half of the force, but doubles the cost. Distance, and can not change the direction of force. The force direction of the fixed roller is equal, no matter where it is, the force used to lift the weight is equal.

 

So, what is the structural composition of the aluminum alloy door and window roller? Usually it is mainly composed of several important parts of the lower roller, the upper roller, the fixing screw and the lower roller traction screw. The selection of the upper and lower rollers should be noted that the poor rollers are very noisy and the operation is not smooth and smooth, so pick the good quality rollers when selecting.
