SR-D Series Linear Actuators

The WEISS SR-D Series of linear actuators represents a class of highly engineered products built around a precision ball screw drive and two parallel, integrated, zero-backlash rail guides.

Designed with compact dimensions, these actuators deliver exceptional performance characteristics - specifically high speeds, rigorous accuracy, and exact repeatability. These strict operational tolerances make the SR-D series exceptionally well-suited for demanding industrial applications requiring absolute structural certainty, such as aerospace component manufacturing and advanced metrology positioning systems.

Core Mechanics & Load Handling

At the structural core of the SR-D series is a compact, precision-extruded aluminum profile. The integration of the parallel, zero-backlash rail guide systems within this profile allows the unit to handle high load capacities and execute optimal motion cycles, even when moving larger masses at high velocities. Furthermore, the units are inherently modular and can be easily combined to construct complex, multi-axis positioning systems.

Environmental Protection

To maintain exact precision in active manufacturing environments, the internal mechanics are fully shielded. Two parallel, circulating, anti-static polyurethane sealing strips work in conjunction with an aluminum cover to protect the internal ball screw and guide rails from dust and other particulate contaminants.

Maintenance & Integration

Routine maintenance is streamlined through dedicated carriage lubrication ports, which allow for the easy re-lubrication of both the ball screw and the rail guide systems without disassembling the unit. Additionally, the external aluminum profile features integrated T-slots, providing secure, flexible mounting points for fixing the linear unit into a machine bed, as well as for attaching necessary sensors and switches.
