About Speed Controls
Speed controls, including speed regulators and rate controllers, are used to decelerate and regulate the speed of loads such as moving carriages and machining feeds near the end of their travel. They frequently use fluid dampening methods such as a piston and cylinder combination with controlled fluid flow through an orifice. The regulator method for speed controls is important to consider. Regulator methods include hydraulic, air, gas, and elastomeric. Hydraulic speed controls utilize hydraulic liquid to absorb shock and dampen or slow motion. Air regulated speed controls use atmospheric air to dampen and absorb shock. Gas regulated speed controls utilize a special gas other than air to absorb shock; nitrogen is one common example. In an elastomeric speed control a synthetic elastomer or rubber is used to absorb shock or impact.
