The adoption of the best bearing V considering the balance with the ball spiral shaft on the rigidity, we utilize high-rigidity
low-torque angle ball bearing (contact angle 30X, DF combination). Meanwhile, the tiniest supporting unit, EK/FK4, 5, 6, 8,
is installed with the tiniest angle ball bearing, which is developed for the tiniest ball spiral shaft. The contact angle for this
bearing is 45X, with small ball diameter and more ball quantity, which can provide high rigidity and precision offering steady
rotation energy. Shape of supporting unit V provided with options: angle series and round series, in accordance with
applications. small and easy installation V supporting unit is designed for small space for installation. Meanwhile,
installed with pre-adjusted and pre-stressed bearing, it can be assembled right after delivery, which can reduce the
assembling man-hours and increase the precision of assembly.
