Description

Material
Steel electro zinc-plated.
Note
Undersprung ball transfer units allow for even distribution of loads for goods with uneven surfaces.
When used in machines such as punch presses and bend form machines the ball rollers spring back up after the forming process and the finished article can be rolled off.

By the “End tension (N)” the ball has completely receded into the housing.
Drawing reference
1) load ball
2) bearing balls
