Antibackbend chains - iwis drive systems LLC

Antibackbend chains, flexible in only one direction, are used for pushing loads and can bridge larger gaps without a guidance system. Applications include adjustable operation chairs, hospital beds, or mixing units for dental impressions.

The chains transmit tensile and compressive forces over longer distances without the need for a guidance system. Similar to linear drives, the units eliminate the need for an endless, circulating chain drive. The side and backbend capability is individually adjustable within certain limits. The chains can be made in various sizes, configured for application-specific drive concepts, and are available in various materials with a range of surface finishes and lubricants.
