1. If the machine length is 1m and 2m and the roller pitch (P) is 75 and 150, the actual roller pitch will be 77 and 154 respectively.
2. Curves are applicable for nominal roller widths of 240mm or more. (For nominal widths of 890mm and 990mm, a 90° curve is divided into two 45° units.)

Note: The above figures are for no impact.

Note) The above is calculated with an allowable bending stress of 100 MPa and a deflection of 1/500.
