Rotary rodless cylinder price is driven by compressed air and can work normally in harsh conditions such as flammable, explosive, high temperature, vibration, humidity, dust, etc. Rotary rodless cylinder types has an overload protection function and can be started directly with load; Rotary rodless electric cylinder can operate continuously at full load for a long time. It is mostly used in high-speed and constant load conditions. The working principle of volumetric rotary rodless guided cylinder is similar to that of hydraulic rotary rodless piston. It can be divided into vane type, piston type, gear type, etc. according to the structural form.
