The Ball Screw is a high-efficiency method of converting rotary motion to linear motion by using a recirculating ball mechanism between the screw shaft and the nut. Compared with a conventional sliding screw, the ball screw requires driving torque of one-third or less, making it ideal for saving drive motor power.
The nut bracket is standardized for standard Ball Screw assembly provided with finished shaft ends. This model is designed to be secured directly on the table using bolts. Since the height is low, it can be mounted on the table only using bolts.
The Support Unit comes in six types: models EK, FK, EF, and FF, which are standardized for standard Ball Screw assembly provided with finished shaft ends, and models BK and BF, which are standardized for ball screws in general. The Support Unit on the fixed side contains a JIS Class 5-compliant angular bearing provided with an adjusted preload.
The Lock Nut for Ball Screws is capable of easily fastening the screw shaft and the bearing with high accuracy. A loosening prevention mechanism comprising a hexagonal socket-head setscrew and a set piece prevents the Lock Nut from loosening and ensures firm fastening.
