Reference-class linear drive
Combines high precision, high forces, and high dynamics.
High-quality components
Ball screw for high velocities and a high number of cycles. Nonrotating tip for uniform motion prevents wobble, torque, and wear at the point of contact. Incl. flat and spherical tip for decoupling forces. Noncontact limit switches protect the mechanics. A direction-sensing reference switch supports automation applications. Position-controlled variants with differential encoder driver in the connector for safe signal transfer over distances up to 10 m.
