THK BNS4040+700LC5

The THK BNS4040+700LC5 is a heavy-load ball screw from THK’s BNS series, designed to provide simultaneous linear and rotary motion with high rigidity and durability. This model features a 40 mm screw shaft diameter, a 40 mm lead, and a 700 mm overall shaft length, making it suitable for demanding industrial automation, indexing mechanisms, and high-load positioning applications. The BNS series integrates a ball screw and ball spline structure in a single unit, enabling torque transmission while maintaining smooth axial movement. This configuration is especially effective in applications requiring synchronized rotation and linear travel without backlash.
