Compact Design
The TECHNICA rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double acting and spring return units.
Namur Mounting
Namur VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners.
Degree of Travel
The standard angle of rotation is 90°. Additional travel rotations of 120°, 135°, 150° and 180° are available. For sizes from UT16 and larger, TECHNICA features dual travel stops that provide for ± 10° stroke registration on both the opening and closing phases of the actuator stroke. 110° of travel in a standard 90° actuator!
Bottom Mounting Flange
The “patent pending” bottom plate design, unique to TECHNICA, secures a captive pinion (anti-blowout system) and permits flexibility in mounting by retaining AISI 304 nuts (standard) or AISI 304 bolts (optional) in either dual ISO patterns, or to customer dimensions.
Flexible Output Shafts
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.
High Cycle Bearings
Shaft bearings isolate the pinion gear from the housing and support the shaft for high cycle applications. Many competitive manufacturers do not provide this critical feature.
Rugged Tooth Design
The pinion teeth are engaged the full length and stroke of the piston. The pinion height allows manual override without disturbing the indicated positions.
High Visibility Position Indication
External open/close indicator as standard, available for all the rotations.
Working Temperature
Standard working temperature range of Buna seals -20°C to 80°C (-4°F to 176°F).

Low Temperature
Low temperature with Silicone seals -48°C (-55°F) High temperature with Viton seals to 121°C (250°F); 149°C (300°F) cyclic
High Cycle Life Wear Pads
Pistons incorporate double wear pads to separate the rack from the actuator wall and serve as both guide and wear bearings.
Pre-Loaded Spring Cartridges
Epoxy coated special steel springs are pre-loaded with non-metallic materials. The stainless steel end cap fasteners are extra long to allow for spring relaxation. All parts are corrosion resistant.
Alternative Operating Media
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.
Stainless Steel Fasteners
All external fasteners are corrosion resistant stainless steel.
Honed Bore for High Cycle Life
Extruded aluminum body is internally machined and lapped to exact specifications. Honing prevents dry spots from forming within the actuator bore and therefore eliminates premature seal failure - a critical aspect to long cycle life. All internal and external surfaces are hard anodized for corrosion resistance, with all units permanently lubricated at the factory with non-silicone grease.
All units are externally stamped with a progressive traceable serial number.
Quality Assurance
100% of all units are factory pressure and leak tested, and individually boxed for shipment.
