Bell-Everman’s drop-in replacement actuator


Bell-Everman’s ServoBelt RA, a new high-performance, drop-in replacement actuator designed for applications that traditionally use rod actuators, pneumatic cylinders, or linear motors, is fully guided along the entirety of its stroke, making it more resistant to off-axis loads and more stable in on-axis moves.

With linear forces up to 200 N, speeds up to 4 m/s, accuracy to ±4μm per meter and bi-directional repeatability as low as ±25μm depending on deceleration profile, ServoBelt RA performance compares favorably to linear motors that cost thousands more.

ServoBelt RA is built from the ground up for moving chassis installation in both horizontal and vertical Z-axis orientations. Its drive unit features standard or custom mounting hole patterns for easy integration into machines. A range of standard motor offerings enables the replacement of pneumatic cylinders by connecting DC power and rerouting servo-valve signals to the ServoBelt RA.
