Vacuum Lead Screw Linear Actuators
Spotlight vacuum lead screw linear actuators can be configured from every standard lead screw motor platform for 10⁻⁷ Pa service while retaining the electrical, mechanical and motion parameters of the corresponding standard model.
A vacuum linear axis configured around your motion requirement
Each assembly is specified around the equipment envelope, target motion profile and vacuum operating conditions instead of forcing a fixed catalog configuration.
Vacuum options across the range
All standard lead screw motor platforms can be adapted for vacuum service, with materials, lubrication, cabling and connectors selected for the application.
Application-specific motion design
Frame size, screw lead, travel, winding and mechanical arrangement are matched to the required load, speed and positioning duty.
Integration-ready mechanics
Motor, lead screw and nut geometry can be coordinated with mounting constraints, available space and the surrounding machine structure.
Standard performance with vacuum compatibility
The vacuum version keeps the corresponding standard product’s frame, winding, lead screw, thrust or load rating, travel per step, motor length and mechanical dimensions. Vacuum-compatible materials, lubrication, cabling and connector options are applied for 10⁻⁷ Pa service.
Vacuum versions mapped to standard SP series

Voltage, current, resistance, inductance, step angle, motor length, travel per step, screw diameter, configuration and mechanical dimensions remain the same as the selected standard SP series product.
Vacuum versions mapped to standard SP ball screw series
| Standard model | Frame size | Recommended load limit | Ball screw lead | Vacuum level |
|---|---|---|---|---|
| SP14BSA | 14 mm | Up to 15 N | 1 / 2 mm | 10⁻⁷ Pa |
| SP20BSA | 20 mm | Up to 45 N | 1 / 2 mm | 10⁻⁷ Pa |
| SP28BSA | 28 mm | Up to 140 N | 1 / 2 / 6 mm | 10⁻⁷ Pa |
| SP35BSA | 35 mm | Up to 230 N | 1–12 mm | 10⁻⁷ Pa |
| SP42BSA | 42 mm | Up to 230 N | 1–10 mm | 10⁻⁷ Pa |
| SP57BSA | 57 mm | Up to 910 N | 2–20 mm | 10⁻⁷ Pa |
Load figures are the recommended upper limits stated for the corresponding standard product under its reference test conditions. Electrical, travel-per-step, accuracy, screw, nut and mechanical data follow that standard product.
