For applications where the unique Compensation System, with uncompromising angular accuracy cannot be installed, Hydroblock offers 2 types of products:
THREE-BALL ROTATION
A rototranslation system with three balls arranged at an angle of 120° designed to enhance the mechanical resistance of the system and to keep the inevitable angular clearance within minimum tolerances. Thanks to the force distribution along three rotation paths positioned over a large diameter, the rototranslational clearance is maintained in the long run. Although the cylinders will inevitably feature an increasing angular clearance cycle by cycle, this process will take longer with the three-roll system than with solutions based on two balls.
TWO NON-COMPENSATED BALLS
If the rototranslation system with three balls can`t be installed, we offer the conventional 2-roll rotation system. The two balls arranged over a large diameter will enhance high mechanical reliability in the long run and thus improve the rototranslation clearance for a prolonged period a time. As the cylinders will inevitably feature an increasing angular clearance cycle by cycle, we recommend limiting the swinging speed of the cylinder to a minimum value.
These cylinders are characterized by sturdy design, unparalleled reliability and maximized bolt and ball diameters.
They are made of alloyed and heat-treated materials.
This swing clamp cylinder type inevitably features slight angular clearance that increases over time. For applications requiring high repeat accuracy in the positioning of the clamping arm, we recommend using the SR COMPENSATION SYSTEM version.
