Ball Screw Based Linear Translation Stages of series 8MT165 are based on 3 phase ironless linear brushless servo motor technology (version with stepper motor available by request) . BLDC technology allow user to reach motion with high accuracy, repeatability and low wear.
Rotary non-contact optical encoder as a feedback system guarantees in-direct control of position with sub-nanometer resolution of motion.
Naturally aged aluminum alloy guaranties high temperature stability, softness of 8MTL165 instruments and excellent long period kinematics without drift of guide system. Special guiding system with recirculating balls ensures long-lasting linear positioner precision.
Linear translation stages of series 8MTL165 can be prepared for clean rooms and vacuum up to 10-3 Torr. For higher vacuum please contact Standa. Higher cleanliness requirements could be requested additionally.
Motorized translation stage can be easily connected to standard imperial/metric optical table directly. XY configuration stages can be assembled by direct stacking without using any connecting plates. Standa could deliver assembled preset XY system with extremely high orthogonality for additional cost.
Motion control of 8MT165 series translation stages is available with Standa or ACS motion Controllers & Drivers in exposed or housed configurations.
For industrial applications 8MT165 stages can be supplied mounted on standard optical table or extremely flat granite plate fully sealed from spray and dust to ensure performance of kinematic pairs
