Ultran Slide Rodless Cylinders from Bimba Manufacturing Co., Monee Park, Ill. (www.bimba.com), use three rare-earth magnets on the carriage and three matching magnets on the piston to create a strong bond holding the carriage and piston together. So when the cylinder actuates, the piston and carriage move back and forth as one unit. The magnetic attraction also determines the cylinder’s coupling strength, which is one of the highest available for rodless cylinders on the market. This lets it carry higher loads without the piston uncoupling from the carriage.
Piston seals are internally lubricated, which extends their life. Optional shock absorbers decelerate loads while optional bumpers reduce noise. The devices can also be equipped with end-of-stroke sensors.

The cylinders come in a variety of sizes with a range of stroke lengths.
