High Precision Motorized Linear Stage: PT-GD140M
Product characteristics:
※ Precision ball screw drive, good repeated positioning accuracy and alignment positioning accuracy, small axial clearance and long service life.
※ Precise linear slider guide (square, connected with the base plate as a whole) is adopted for the guide rail, which is comfortable in movement and large in load, and suitable for single axle heavy load or multi axle combination.
※ The precision grinding of the bottom plate of the electric moving table and the reasonable guide rail fixing method greatly reduce the pitch and yaw of the electric moving table, and greatly improve the straightness and parallelism of the movement.
※ The servo motor can be replaced, and the grating ruler is used for closed-loop control to achieve high speed and heavy load.
