3. Rotary motion with RBR An RBR (reverse bending radius) is when the energy chain can travel in two directions. Each igus® energy chain can incorporate
RBR designs, with the exception of certain radii for Energy Tubes R117 to R98 and for Series 07, 09, 14, 15, and 17. The RBR does not necessarily need to be identical to the normal bending radius of an energy chain. Part No. 280-15-100/425-0 describes a Series 280 energy chain cable carrier with an inner width of 5.91 inches (150 mm), standard bending radius of 3.94 inches (100 mm) and RBR of 16.73 inches (425 mm). Most rotary motions can be achieved with the RBR option. Angles of rotation up to 540° are possible. Below is an example of rotary motion using an RBR energy chain. Please consult igus® for your particular application.
Options 2. and 3. for rotary movements require less installation height. The energy chain cable carriers glide mostly on surfaces made from polymer, stainless steel or steel and are guided through channels into a rotary movement. Read about side-mounted applications for additional design tips. Bending radii, circular radii and e-chain® widths are variable with this product line.
