We at Gimson Robotics are one of the most popular suppliers of linear actuators, DC electric motors and control accessories in the UK, with full product support available. We are highly knowledgeable in our field, insured, and VAT-registered. Prices include 20% UK VAT and VAT invoices (printed) are supplied with every order. This listing is for a GLA4000-S model linear actuator, a powerful 12V DC (direct current) actuator designed for heavy loads and quality-critical applications. Each actuator is capable of providing up to 4000N (407kg, 897lbs) of pushing or pulling force at the rated voltage.
The no-load travel speed at 12V is 11mm/s while at the full rated load the travel rate is 8mm/s. This model is currently stocked in seven different stroke lengths (travel distances) of 50mm (2"), 100mm (4"), 150mm (6"), 200mm (8"), 300mm (12), 400mm 15. Each of these actuators is built to last with corrosion resistant materials used throughout the exterior, along with seals and a central rubber-surround ensuring that the actuator is splash-proof and suitable for most covered outdoor use (be aware that direct long-term water exposure should be avoided, but only basic covering is required in most cases).
Oth the front and rear mounting points are constructed from sturdy metal, unlike the plastic brackets used by some rival products. The low noise output and smooth operation of this actuator make it perfect for powering adjustable beds, furniture, fold-out steps and similar automated features in and around the home. The larger sizes also lend themselves towards the likes of electric gates, ventilation windows and extendable structures. The actuator comes with a 1.4m PVC insulated lead as standard (black external sleeve with two internal cores, one brown and one blue) with uncovered lead ends. To change the direction of travel simply swap the polarity of the DC power source to the two actuator leads (this may be achieved using hardware such as our rocker switch harness or GLA-CU-X2 remote control unit).By varying the input voltage between 0-12V DC it is possible to control the speed of the actuator. Reducing the voltage will also reduce load capacity (for example at 6V the actuator will have roughly half of the maximum load capacity at 12V). This actuator is designed primarily for compression loads, it will typically work OK in tension, up to the same rated maximum load, but can be more susceptible to damage from overloading. Shock loads through the mounting points should be avoided. Experienced users who wish to extract greater power from the actuator (at their own risk) should abide by a practical operation ceiling of 18V, above which the motor, diodes and limit switches of the actuator would be significantly more likely to fail. Be aware that the current draw will be greater if the actuator is run at above 12V DC and the duty cycle should be reduced to help avoid over-heating. Ensure that the control hardware and power source are capable of providing sufficient current for the loads you expect the actuator to experience. We cannot be held liable for damage caused to connected hardware due to inappropriate hardware selection. CAD models (STEP or IGS) of the actuator are available upon request.
Nominal 12V DC, up to 90W. 30% this is the maximum proportion of time that the actuator may be in operation for, up to 2minutes during any continuous stretch. The duty cycle should be reduced below 20% for average loads >2000N. Please be aware that there may some variation in the operating performance from actuator to actuator, as a rule-of-thumb allow for a 5% difference above/below the given values.
If intending to use two actuators together to drive the same assembly connect them in parallel to the input current and ensure that the driven assembly is rigid enough to transfer forces between the actuators (so as to prevent twisting if one actuator is slightly faster than the other). This is the distance from the front to rear mounting hole centres when the actuator is retracted. Add the stroke length to the installation length to get the fully extended hole-to-hole centre distance (for example this is 600mm for the 200mm stroke). One at the end of the cylindrical piston rod, the other towards the rear of the gearbox housing. Both mounting points feature vertical slots to enable a variety of mounting methods.
Aluminium piston-rod and main sleeve, plastic-enclosed steel motor housing, with toughened plastic gearbox surround. Zinc plated steel front and rear brackets. Enclosure rated to IP65, suitable for washing and short-term water exposure. If using outdoors shield actuator from direct rain. Installed internally at ends of travel (fixed-position).
