Ultran Band Mechanically Coupled Rodless Cylinders Bimba Now gives you a more complete set of rodless cylinder solutions with a mechanically coupled style. The Bimba Ultran Band provides all the traditional features and benefits of a band-style rodless cylinder:
A mechanical piston/yoke connection creates a unique sealing challenge, as the cylinder has a continuous break in the bore to allow for the connection. Band cylinders on the market answer this challenge with various approaches. The Ultran Band’s sealing system has been engineered and tested to outperform all other sealing systems on the market by upwards of 75%. By reducing leakage so dramatically, the Ultran Band provides the most cost-effective and efficiently running solution in the industry. The Ultran Band is available in bore sizes 18mm, 25mm, 32mm, 40mm, 50mm, and 63mm. Inch and metric versions are available with standard stroke lengths up to 3m (~10 ft.). Standard features include cushioning and position sensing capability, as well as optional side guiding attachment for increased load capacity. |
