Omnitrack highlight: B21 Spring Loaded Ball Transfer B Bar.
Today we highlight the Omnitrack B21 spring loaded ball transfer bar B. Used mainly in machines and presses, this solution uses several high capacity ball units with spring, housed in a solid steel bar for the movement and positioning of tools and dies. KNOW THE CHARACTERISTICS of this solution.
The patented ‘double recirculation’ internal mechanism provides the lowest coefficient of friction available in all ball transfers so heavy tools and dies can be positioned very accurately with relative ease. Once they are in place, the springs in the B21 B bar allow the ball units to retract into the machine bed when extra load is applied from above to clamp the tool in place. When relieved of the extra load, the ball units then raise the tool or die from the machine bed surface and permit ‘frictionless’ movement once more.
The B21 is 250mm [approx. 10”] in length and features 6 spring loaded ball transfer units providing a combined preload of 168 Kg. At one end of the B bar there is an M8 cap screw which holds the bar firmly in place when wound into a corresponding tapped hole in the press bed.
If the dimensions or load ratings of the B21 are not quite suitable for your specific application, most of the dimensions of the T and B bar ranges can be adapted so that they are tailored to a particular press or machine bed. A greater or fewer number of ball units can be installed into the bar depending on the optimum spacing you require to move the heavy tooling or dies.
