The easy-to-install support unit boasts a compact design, meticulously crafted to fit seamlessly within the installation space. At the
same time, the bearings come pre-adjusted and preloaded, allowing for immediate assembly upon delivery. This feature not only
reduces assembly time but also enhances overall assembly accuracy.
BK Series
The fixed-side support unit is equipped with JIS5 class angular contact ball bearings, precisely adjusted through preloading. Of particular note are the ultra-miniature EK6 and EK8 types, which feature ultra-miniature angular contact ball bearings with a 45° contact angle, designed specifically for ultra-miniature ball screws. These bearings offer exceptional rigidity, precision, and stable rotary performance. The support-side unit employs deep groove ball bearings. Each support unit in the EK and BK series comes pre-loaded with the optimal amount of lithium soap grease and is sealed with specialized gaskets to ensure long-term performance. (1) Employing the finest bearings, the design balances rigidity and torque efficiency using high-rigidity, low-torque angular contact ball bearings with a 30° contact angle. The ultra-small EK6 and EK8 units showcase ultra-small angular contact ball bearings developed for ultra-small ball screws, featuring a 45° contact angle, high ball count, and small ball diameter, ensuring outstanding rigidity, precision, and stable rotary performance. (2) The support units come in both angular and circular series, offering flexibility based on application needs. (3) The compact, easy-to-install design considers surrounding space constraints, allowing for straightforward installation. Furthermore, the pre-adjusted and preloaded bearings facilitate immediate assembly after delivery, effectively reducing assembly time and enhancing accuracy.
