If you use four units of IK-51 for a cargo of 1,000 kg against the rail of the hardness of HRC55 or equivalent grade, the initial resistance is about 15kg. If the SS metal is used, the figure will be double or more.

If the hardness of the ball transfer is HRC62, you should examine the hardness of the rail. Initial resistance will differ depending on the hardness.
