FLUID POWER: Kollmorgen introduces EC1 Electric Cylinders - a cost-effective, high-performance linear positioning alternative to pneumatic and hydraulic systems in applications requiring continuous thrust of ≤150 lb (660N). They deliver all the benefits that electric cylinder users have come to expect such as smooth, controllable speed (up to 0.325 m/s [13 in/s]), accurate mid-stroke positioning and position holding without power (with brake option), in the most compact electric cylinder package available to date from Kollmorgen.EC1 electric cylinders deliver standard stroke lengths from 50 mm up to 200 mm, and can handle maximum payload weight of 150 lb at 100 percent duty cycle. The EC1 can deliver repeatability to ± 0.001 inch with lead accuracy to ± 0.004 inch/ft., with backlash of just 0.015 inch. This performance, coupled with a compact 4.60 inch + stroke length x 1.89 inch x 3.25 inch (117.0 mm + stroke length x 48 mm x 82.6 mm) footprint, make the EC1 ideally suited for use in space-restricted applications such as testing systems, test sample placement in medical applications and general factory automation machines where precise, repeatable motion is a must.
The choice between helical and spur gears in gearboxes may seem straightforward. But with planetary gearboxes, however, the choice between helical and spur gears requires some additional thought. Here’s what you need to know to make the right choice.
