a linear guide way structure . the structure utilizes spring strips to combine a sliding body assembly and end caps , instead of using screws or pins . the sliding body assembly and the end caps are combined together with an almost constant resilient force provided by the spring strips whose mechanical strength is greater than that of plastic material . the problem of exfoliation between two physically different materials such a metal and plastic never is avoided . accordingly , the linear guide way is easy to fabricate , operate , and maintain with low cost .
