Electric linear actuators · engineering & manufacturing from one source

When standard is not enough.

S+R develops electric linear actuators from the load case outward – individually engineered, robustly built and traceably documented.

Solutions

We translate technical tasks into robust motion solutions.

The entry point may be a new development, retrofit, series assembly or repair. What matters is that the solution fits the problem: technically sound, commercially appropriate and traceable later in service.

01

Engineering

Sizing force, stroke, speed, installation position, motor, sensors and control.

02

Electric actuators

AP, SP and XP as proven design principles for standard-adjacent and custom solutions.

03

Manufacturing

Machining, assembly, testing and documentation from one source.

04

Repair

Repair, spare parts and retrofit support, also for older electric linear actuators and installed units.

05

Control

Limit switches, encoders, potentiometers, positioning and synchronous control systems.

06

Series & OEM

Repeatable assemblies, defined variants and technical alignment for serial demand.

Industries

Typical tasks instead of an abstract product catalogue.

Many inquiries do not start with a product range. They start with a machine: flap, slide, format adjustment, test bench, retrofit or series assembly. The industries lead faster to the right technical question.

Reference projects

Real-world project examples show how S+R thinks.

With technical challenge, solution route and result. This shows how a load case becomes a matching assembly.

Heavy-duty actuator for a lock system after 20 years in service

A heavy electric actuator from a lock project returned to the S+R workshop after roughly 20 years in operation for service and service-life assessment.

Short installed length for a compact machine module

An existing machine geometry left very little axial space but required a robust lifting motion.

Retrofit solution for an older installed system

An existing drive was no longer economical to repair and needed a mechanically compatible replacement.

Technology building blocks

AP, SP and XP as proven design principles.

The product families show how S+R typically builds force line, space, protection, sensors and control. For customer projects, these principles are adapted, combined or extended.

Motors & motion control

Platform-open: classic three-phase – or servo for motion control.

We build the actuator. You choose the motor that drives it – from a robust three-phase motor to a servo drive for demanding motion control.

Classic: three-phase motor

Robust, economical standard solution for reliable lifting and positioning motion – proven and long-lasting.

Motion control: servo – platform-open

For precise, dynamic and networked motion we equip the actuator with all common servo motors – e.g. SEW, Beckhoff (EtherCAT), Fanuc, Siemens (PROFINET, SIMOTION) – exactly as it fits your control environment.

Customer-supplied servo motors are possible: you provide the preferred motor, we integrate it into the actuator.

Process

How your motion solution is created.

We guide each project from the first load case to the right solution: technically sound, commercially appropriate and as specific as needed - no more and no less.

01

Inquiry

We assess force, stroke, environment, installation position and existing drawings, then identify early what really matters.

02

Sizing

With experience from engineering, manufacturing and service, we select the product range, spindle, motor, sensors and protection class to fit the problem.

03

Manufacturing

Once the technical route is clear, drawing, assembly, testing and documentation come from one source.

04

Service

After delivery, repair, spare parts, retrofit and technical questions remain traceable and supported.

From one source

Manufacturing, testing and service directly at the component.

Series production, custom builds and service work together so load case, interface and documentation remain traceable for engineering, purchasing and maintenance.

Repeatable assemblies from in-house production.
Series & OEM

Repeatable assemblies from in-house production.

Spindles, bearings and connection geometry are prepared so serial demand and spare-part supply remain traceable.

Technical inspection directly at the component.
Assembly & assessment

Technical inspection directly at the component.

Service cases, retrofit and new designs are handled by people who understand both mechanics and the application.

Heavy-duty cylinders for real machine environments.
Custom build

Heavy-duty cylinders for real machine environments.

When force, stroke, mounting or environment differ from standard, the solution is built from drawings, load case and manufacturing experience.

Component quality

Brand components selected around the task.

An electric actuator is only as reliable as the combination of screw, motor, gearbox, coupling, brake, sensors and interface. Depending on the load case, S+R uses proven components from established manufacturers and integrates them into a testable S+R assembly.

Typical use cases

For machine builders, OEMs and maintenance teams worldwide.

This experience becomes relevant where standard catalogues end too early: high forces, limited space, harsh environments, retrofit and documented series capability.
