SP · product family

Compact thrust when machine space is limited.

Name: SP series electric linear actuator
Brand: S+R Linear Technology

SP places the drive parallel or at an angle to the axis. The assembly stays short while retaining robust spindle technology, sensors and adapted mounting interfaces.

SP series technical view — SP series · IP65+ · up to 500 kN

up to 500 kNforce

up to 3,000 mmstroke

up to 1,000 mm/sspeed

up to 100 % duty cycleduty cycle

Sizes & drive

A standard programme as the basis – sized for the load case.

Design & drive

Drive: Worm-gear motor keyed directly onto the spindle (feather key)
Spindle: Ball screw or trapezoidal screw
Mounting: Eye or trunnion journals, optionally with trunnion brackets

Standard sizes

Five sizes per design. Stroke and speed follow from the actuating force.

Size	max. force
5	up to 8 kN
20	up to 15 kN
30	up to 25 kN
50	up to 60 kN
60	up to 80 kN

Duty cycle up to 100 % ED
Stroke & speed depend on the actuating force
all common motors can be mounted
coating, stainless steel and ATEX possible

For heavy-duty and special cases we also realise much higher forces (up to ~500 kN) as a custom design.

Classification

When SP is the right technical fit.

machine modules with limited axial space and demanding integration requirements

Typical applications

compact machine modules
retrofit with fixed installation space
parallel and angular drive arrangements
lifting motion with protected motor space

Strengths

short axial installed length
flexible motor position
good integration into existing machines
high adaptability

Check before selection

define gearbox and motor position early
check access for assembly
derive mounting points from the drawing

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.

EtherCAT

PROFINET

SIMOTION

Fanuc

SEW

Beckhoff

Siemens

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

Options & variants

Tailored to the load case – not off the shelf.

Design and size are only the start. Mounting, protection, adjustment and finish are specified to suit the machine and environment.

**Dual drive / synchronisation** Two actuators mechanically coupled by a connecting shaft – synchronous motion without control effort.

**Bellows** Protects the piston rod and spindle against dirt, dust and splash water in harsh environments.

**Flange mounting** Front flange for a stiff, defined connection to the machine structure.

**Handwheel adjustment** Manual emergency or fine adjustment directly at the gearbox – even without power.

**Stainless steel version** Corrosion-resistant for hygiene, outdoor and wet areas – up to a full stainless build.

**Foot mounting on the barrel** Additional support via clamps or feet on the barrel tube – ideal for long strokes.

**Heavy duty from 80 kN** Robust large sizes for high continuous forces – well beyond that as a special build.
