Ball Screw SFU2005-200MM~2500MM Set + 6. Ball Screw Support Bearing, Contact Angle 60 Degrees , Bore Dia. TAB series ball screw support bearings with seals: Seal is integrated into a ball screw support bearing with great axial rigidity. Ball screws convert rotary motion to linear motion, or torque to thrust, and vice versa. The BG Type Ball Screw Linear Actuator offers compact dimensions, which outperforms conventional positioning tables. Solved Example. With high load carrying capacity, low friction and great stiffness these ball screw support bearings are used in machine tools to help feed work pieces into the machine quickly efficiently and accurately. thomsonlinear. HS Series ball screw jacks with travelling nut:. Ranges of Thompson ball screws. Barden Ball Screw Support Bearings. Ball screws use ball bearings to eliminate friction between the nut and the screw. End supports handle radial loads (perpendicular to the lead screw) and thrust loads (parallel to the lead screw). 5-2 times higher loading capacity than a standard ballscrew series and are capable of higher axial loading due to the reinforced circulation system.
