Rack and pinion pneumatic actuators statement of usage and
selection
Through research development and design rack and pinion pneumatic
actuators incorporate the latest technology materials and
innovative idea. The product proudly boasts the following features.
Full conformance to the latest specifications: ISO5211,DIN3337 and VDINDE-3854,NAMUR.
The extruding high intensity aluminum body possesses a honed internal surface coated with hard anode oxygenation for long life. Low coefficient of friction and swift performance.
Excellent compact and modernized construction along with multi specifications makes the selection both economic and beneficial.
All acting surface adopt high quality bearing resulting in low friction, high cycle life, and no noise
The two independent external stroke adjustment bolts can easily and precisely adjust ±5°at both open and close directions.
Same outline actuators have the functional modes of double acting
and single acting (Spring -Return). The Spring-Return has the
normally-open and normally-close styles.
Multi function indicator with NAMUR is convenient for mounting
accessories.
Pre-compressed load spring is convenient for safe mounting and tear
down procedures.
Die-casting aluminum pistons and end caps have high intensity and
light weight.
Different O-rings materials are available for high and low
temperature.
Solenoid valves are easily mounted without any connecting plank.
Main Features
- Rack & pinion design
- Compact and light weight
- ISO 5211 mounting pattern
- Adjustable stops for both open and closed positions
- Accessory mounting dimensions to NAMUR specifications
- Machined gear teeth provide longest life and smoother operation
- High cycle life with low friction bearings on all moving and
sliding surfaces
- Safety contained springs prevent hazards of inadvertent ejection
during maintenance
- Modular design utilizing same body and end caps for both
double-acting and spring-return versions
- Corrosion resistant with hard anodized body, PTFE coated end caps,
and stainless steel fasteners
