3、Support：The support be used for support the inclined plate, and could adjust the angle of plate in the range of 0～60°.

4、Base：The base should be able to adjust and maintain the device in the level.

5、Catching ball box：Catching ball box be used toreceiving rolling steel ballon the plate, inside with the soft material.

Steel ball

   Made of GCr15 bearing steel the accuracy of it is not lower than “0” level of regulation of GB 308-77 steel ball, it is the 33 kind steel ball which diameter is 1 inch, could be used as test steel ball.

The steel ball is name the ball number according to the 32 times according to the inch diameter. Should use a set of steel ball that it is continuous number

Steel ball should be stored in anti-rust oil. The rust and scars ball should change in time.

Cleaner and wipe the material
