Overview
Large Travel Motorized Linear Stage PP120-(50-300)
Precision ball screw drive, good repeatability and absolute positioning accuracy, small axial clearance and long service life; The guide rail adopts precision linear bearing guide rail (supported at both ends and suspended in the middle), with small load, suitable for single-axis scientific test, and good vertical use effect; The servo motor can be replaced, and the grating ruler is used for closed-loop control to realize high-speed and heavy-load.
Product characteristics:
Step motor is equipped as standard, and the company's ZD-KZ series motion controller can realize automatic control of it.
Driven by imported precision ball screw, it has good repeated positioning accuracy and absolute positioning accuracy, small axial clearance and long service life.
The anti-loose and anti-axial movement structure can effectively prevent the screw from loosening and axial movement, effectively ensure the repeated positioning accuracy and positioning accuracy, especially suitable for high-speed reciprocating use.
The guide rail adopts precision linear bearing guide rail (supported at both ends and suspended in the middle), with small load, suitable for single-axis scientific test, and good vertical use effect.
The reasonable adjustment and fixation method of guide rail greatly improves the installation accuracy of guide rail, effectively ensures the straightness, parallelism and comfort of movement.
The stepping motor and ball screw are connected by high-quality elastic coupling, which has good anti-bias performance, greatly reducing eccentric disturbance and low noise.
Equipped with handwheel, convenient for debugging.
Zero and limit switches are installed at both ends to facilitate accurate positioning and protection of products.
The base has threaded holes and through-holes with standard hole spacing, which is convenient for installation and fixation.
The servo motor can be replaced, and the grating ruler is used for closed-loop control to realize high-speed and heavy-load.
