Rotary actuators

The pneumatic rotary cylinder GRCseries is an actuator whose rotary motion is obtained by the action of compressed air on a piston that drives a rack. In turn, the rack drives a pinion causing the plate to rotate. The drive pinion, mounted between 2 bearings, drives the plate on which the load can be directly fixed. In addition, the GRC series rotary tables allow the direct installation of heavy loads and the realization of very precise positioning thanks to guide bearings. Compactness and high precision are also the major advantages of the GRC series. On the other hand, assembly and installation are facilitated by supply ports on one of the 3 sides as required.

Features

• Slow or fast speed (0.2 to 25 sec. for 90°)
• Reliable operation thanks to external shutter

Excellent design freedom

• Smallest size on the market: GRC-5 - 0.5 Nm
• 6 sizes are now available: 5, 10, 20, 20, 30, 50 and 80
• Selection of standard or high precision model with the same dimensions
• Available in 90° or 180°

Easy installation

•  Pneumatic connection possible on 3 sides
•  Simplified piping and cabling with a large central hole
•  The threads and centring pins are provided on the plate (4 positions) and under the body

The pneumatic rotary cylinder RRC series is a rack and pinion actuator whose combined action of the 2 racks and the pinion provides stable torque even at low pressure. In addition, internal and external leaks are reduced as in a linear cylinder. This also allows the cylinder to have a longer service life.

Features

• Compact cylinders
• 3 Effective torque: 0.7 to 5.6
• Rotate: 90°, 180°, 270°, 270°
• Male shaft, end of stroke damping (pneumatic or hydraulic)
• Model with available angle adjustment

The rotary pneumatic cylinder series RJC (40, 63 and 80) is a double-acting oleopneumatic pneumatic cylinder, consisting of a piston with a chain seal coupled to a drive shaft. Indeed, it is a dual power actuator, thanks to the two cylinders included that generate the thrust at the same time. The integrated hydro cushion reduces shocks at the end of rotation and increases the stopping capacity of the road and its aluminium body gives it a high tensile strength. In addition, the tubular shaft provides ease of assembly and use of the air piping. It is also recommended to pay attention to the choice of the position of the fasteners on the shaft and the direction of rotation when installing them.

Features

• Oleopneumatic cylinder (Air-Oil)
• Pneumatic supply and chain connection between pistons and drive shaft
• Hydraulic end of stroke damping (high damping capacity)
• Hydraulic movement control, smooth rotation at low speed
• Easy assembly of the shaft drive by centring
• Smooth rotation in the low speed field
• Adjustable end stop by adjusting screw
• SDRJ is the base that attaches the shock absorber to each item (choice rubber)

The RTU series rotary pneumatic cylinder (25, 40 and 50) is a double-acting rack and pinion type actuator for a low tolerance transmission of drive power in a single rotational movement. It consists of an aluminium body for high anodised resistance, a rectangular rotating unit for rotation in both directions of the two clamps and a suction flange to facilitate connection to an application-specific adapter plate. Also equipped with an internal shock absorber, the RTU series cylinder considerably reduces shocks at the end of rotation and thus increases the stopping capacity of the road. It is recommended to use a lightweight finger such as the AF28D and it is also easy to mount when used and associated with the AF30 or AF46 series.

Features

• 90° rotation
• 2 mounting flanges for on-board equipment (e.g. clamps)
• Easy and direct mounting of JRT clamps series AF30 or AF46
• Integrated shock absorbers at the end of the stroke
• SDRJ is the base that attaches the shock absorber to each item (choice rubber)

The SDRJ series rotary pneumatic cylinder (16, 20, 25, 25, 30, 40, 50 and 63) is a rack and pinion type actuator, for a low tolerance transmission of drive power in a single rotational movement, and consists of a hole through the shaft to allow the passage of air tubes or electrical cables. In addition, its aluminium body allows it to have a high tensile strength

Features

• High stopping capacity thanks to shock absorbers
• Integrated support and shoulder to reduce end of stroke tolerances
• Rack and pinion type rotary actuator with double internal piston
• Saving of power tube per center through the bore and easy assembly
• Identical stopping power with a rotation power reducing the moment of inertia of rotation
• Mounting block for inductive proximity switch

The PSM2 series rotary pneumatic cylinder is a cam-type rotary cylinder. The piston is set in motion by the pneumatic pressure. It moves linearly from the front stop to the rear stop (and vice versa). During its translation, the piston is simultaneously rotated by the rollers and its groove. Since the two grooves are opposite, the rotation angle is doubled with respect to the piston stroke.

Features

• Torque up to 130 Nm at 10 bar (78 Nm at 6 bar).
• Rotation angle: 90, 180° or 360° (other on request)
• Adjustable shaft position: Facilitates cylinder assembly
• Can be used from 0.5 bar due to high quality gear machining and the use of low-friction seals

Persuasive technology

Operating pressure max. 10 bar
Thanks to the use of low-friction seals, the rotary cylinder can operate from a working pressure of about 0.5 bar.

Large contact surface
All-wheel drive torque, even under high load conditions
Proven technology in hydraulics

Extremely light and compact design
The combination of aluminium and plastic alloys results in a very lightweight rotary cylinder

Keyed male shaft
The standard version of the PSM2 has a keyed hollow shaft. As an option, a keyed male shaft can be inserted and fixed with a central screw. Other types of shafts can be supplied: square shaft, splined shaft, consult us.

Threading for control axes
The tapping of the through shaft allows position sensors to be mounted at the rear of the cylinder.

Angle adjustment (standard)
The rotation angle can be changed at any time by +/- 5°

High-strength friction surfaces
Long service life
Low friction
Low internal clearance

Perfect tightness
Longer seal life
No internal leakage

Torque, efficiency
The torque is constant in both directions of rotation and throughout the rotation. Perfect sliding of the parts, low friction seals and reduced friction allow high yields to be achieved

Rotation up to 360° or more
Standard rotations 90°, 180°, 360°, 360°
Intermediate and greater than 360° rotation angles are also possible
