AP · product family

Axially guided thrust for high loads and clear installation conditions.

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

AP is the right choice when the force line needs to remain direct, robust and easy to access. Motor, gearbox, spindle, sensors and mounting interfaces are specified around the load case.

AP series technical view — AP 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: Gear motor connected to the spindle via an in-line coupling
Spindle: Ball screw or trapezoidal screw
Mounting: Rod eye and trunnion pins, optionally with trunnion feet

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 AP is the right technical fit.

rough industrial environments, outdoor use, high forces, positioning and synchronous motion tasks

Typical applications

pressing and clamping tasks
flaps, slides and dosing units
test benches and laboratory systems
outdoor and IP65 applications

Strengths

direct force line
very high force ranges
good maintenance access
many motor and sensor options

Check before selection

requires axial installation space
check SP or XP for very short installed lengths
clarify load case and installation position early

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.
