Service throughout the life cycle

Repair, spare parts and retrofit for electric linear actuators.

An electric actuator is part of a machine, not just a spare part. S+R therefore checks whether repair, original part, retrofit or a new solution is the best technical and economic path.

Service fields

The technical route back into operation.

The most important information should quickly reach the right person: type, failure pattern, application and mechanical interface.

01

Register repair

Describe the failure, photograph the type plate and name the application. S+R evaluates whether repair is sensible.

02

Spare parts

Spindle, nut, bearings, seals, motor, limit switches, encoder or control are assigned based on the assembly.

03

Technical support

Load case, installation position, sensors, synchronization, protection class and control questions are clarified technically.

04

Retrofit & replacement

When old units are no longer economical to repair, S+R develops a mechanically and electrically matching replacement.

05

Documentation

Testing, drawings, spare-part logic and connection information create confidence for operation and purchasing.

06

Series stock

Recurring service and spare-part packages can be defined for OEM and distributor demand.

Components & spare parts

Known brand components remain traceable in service.

When motor, gearbox, screw, brake or sensors are documented cleanly, spare parts, retrofit and technical questions can be clarified faster. This is especially useful for older assemblies and serial stock.

Heavy-duty actuator in the S+R workshop for service

Assessment to replacement

When standard is not enough, the interface remains decisive.

Many service cases are not limited by the motion itself, but by existing mounting, space, control and lead time. S+R can record existing machine geometry and derive a matching solution - even when a heavy-duty actuator returns to the test stand after roughly 20 years in service.

Decision
Repair, retrofit or new part

Workflow

Four steps to a reliable decision.

01

Collect data

Type, serial number, stroke, force, voltage, images and failure description.

02

Assessment

Check mechanics, spindle, bearings, motor, limit switches, encoder and control.

03

Decision

Compare repair, spare part, retrofit or new actuator with lead time.

04

Restart

Testing, documentation, shipping and technical support when required.
