GN 509.7

Ball transfer units GN 509.7 are used in machine and device construction for such purposes as to move heavy loads in any direction without the need to exert high levels of force. The spring ensures even distribution of the load over multiple ball transfer units. This is necessary when the load centers of gravity are arranged asymmetrically or when the support surfaces are uneven. The roller bearing of the ball ensures reliable operation and a long service life.

The ball transfer units are inserted from above into a corresponding mounting hole and held by gravity. The load is transferred via the housing collar.
