To meet the increasing demand of suitable high speed Ball Screws, KSS of Japan have developed a 13mm diameter, 30mm lead Rolled Ball Screw. The MRB1330 High Lead Ball Screw allows for rapid yet precise linear movement.
The new MRB1330 can achieved 50% longer travel compared to an existing product of 20mm lead when operating under the same rotary speed. This cost-effective product delivers exemplary linear accuracy through enhanced manufacturing techniques and innovative design. Directly interchangeable with existing shaft diameter 13mm products such as 12mm, 15mm & 20mm, the optimised ball bearing recirculation design enables smooth ball rotation and high-speed durability.
Accuracy grades C7 (+/-0.05mm/300mm) and C10 (+/-0.1mm/300mm) are available. Please note that this product is rated for a maximum of 4,000 RPM and this parameter may change depending on the acceleration / deceleration of the application.
