PI (Physik Instrumente) L.P. Compact High-Precision Direct Drive Linear Stage V-141

V-141 direct-drive linear stages are designed for accuracy, precision, long life, ease of use, and can be mounted in any orientation. A model with integrated counterbalance is available for vertical operation. Even though compact, V-141 linear stages offer superior travel accuracy, flatness, and performance compared to bigger stages. With a powerful, non-cogging, direct drive motor, the V-141 linear stage family performs well in production environments. The ultra-precision cross roller bearings are intended to be low maintenance for the life of the stage. The V-141 is designed for XY and XYZ mounting. The Z model comes with a magnetic counterbalance. Three phase motors for higher dynamics and friction-free, maintenance-free operation The three-phase linear motors driving the V-141 stage family transfer their force directly and friction-free to the motion platform. This eliminates backlash and play that can result from mechanical components like gears and screws in the drivetrain. Ideal for high-velocity, high-acceleration applications, these motors feature a maintenance-free, frictionless design, ensuring longevity in demanding 24/7 operations. The controller's current limit settings allow easy motor disablement, preventing damage to the stage or the application. Crossed roller bearings improve load capacity, accuracy and lifetime Crossed roller bearings offer a superior level of smoothness, straightness, and flatness, close to air bearing performance. By replacing the point contact of ball bearings with a line contact, rollers become considerably stiffer, requiring less preload. The resulting reduction in friction enables smoother running and higher accuracy. Crossed roller bearings can also support higher vertical and moment loads. The anti-creep mechanism prevents roller drift, enhancing reliability. Cleanroom grease is applied for low-maintenance operation.
