ARIS STELLANTRIEBE
With the series Tensor ARIS offers an innovative generation of electronically controlled actuators. The Tensor is based on a low-backlash precision gear in combination with a brushless DC motor. The Tensor´s complete mechanical shut-off system has been replaced by a wear-free, non-contact position detection, which is based on the Hall effect. This sensor technology was developed many years ago for use in the automotive industry and has proved extremely robust, wide temperature range and high reliability.
The actuator drive series Nano has been designed for industrial use. A robust aluminum housing combined with the impact resistant plastic cover reliably protects the drive technology even in harsh environments. Weight savings through the use of a plastic hood in combination with the compact design allow you to use them even on small actuators / fittings. The consistently cost-optimized design in combination with a high quality allows the use in cost-sensitive systems without compromising reliability.
Of course, the Nano is available in all standard voltages (230 V, 115 V, 24 V AC, or 12 V DC).
A stainless steel high-helix spindle with dryspin® spindle nut made of high-performance polymer ensures reliable and maintenance-free operation. Due to the high gradient, the required engine speed is noticeably reduced in comparison to the classic design, so that the engines run significantly smoother and quieter, thus significantly increasing the service life of the engines. Instead of the commercially available castings, anodised aluminum machined parts are used with the Linearis TE, which are significantly more robust with a low weight. The Linearis has been developed by practitioners. Long holes in the brackets allow easy assembly. The dry running spindle nut prevents dirt build-up so that large and expensive bellows designs are no longer required. Likewise, the regular greasing is avoided by the lubricant-free construction.
Single and double-acting pneumatic actuators
Namur VDI/VDE 3845 and ISO 5211 connections on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners.
The standard angle of rotation is 90Åã. Additional travel rotations of 120°, 135°, 150° and 180° are available. PD/PE 15 and upper sizes feature a travel stop wit ±10° in both open and close directions. Other angles (e.g. 30°) are optional.
The female pinion drive is standard with a double square output drive, and optional with a double-D drive, keyed drive and designs to meet your specific requirements.
Shaft bearings isolate the pinion gear from the housing and support the shaft for high cycle applications.
Ambient temperature: -20 °C to +80 °C (optional -40 °C to +150 °C).
The pinion teeth are engaged for the full length and stroke of the piston.
The pinion height allows manual override without disturbing the indicated positions.
External open/close indicator is standard, available indicators for all rotations.
Pistons incorporate double wear pads to separate the rack from the actuator wall and serve as both guide and wear bearings.
PD/PE series pistons feature a keyway as anti-blowout system.
All internal and external components are treated to increase corrosion resistance.
Epoxy coated special steel springs are pre-loaded.
The stainless steel end cap fasteners are extra long to allow for spring relaxation (PE only).
Air pressure operation from 2 to 10 bar (40–150 PSI). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator.
All external fasteners are corrosion resistant stainless steel.
All units are permanently lubricated at the factory with non-silicone grease.
All units are externally stamped with a progressive traceable serial number.
100% of all units are factory pressure leak tested.
