Benefits |
Intrinsically fail safe
|
Ensuring continuous operation of the driveline in the unlikely event of rubber damage. |
Control of resonant torsional vibration
|
Achieving low vibratory loads in the driveline components by selection of optimum stiffness characteristics. |
Maintenance free
|
With no lubrication or adjustment required resulting in low running costs. |
Severe shock load protection
|
Avoiding failure of the driveline under short circuit and other transient conditions. |
Misalignment capability
|
Allows axial and radial misalignment between the driving and driven machines. |
Zero backlash
|
Eliminating torque amplifications through precompression of the rubber elements. |
| Low cost |
The RB Coupling gives the lowest lifetime cost. |

Construction details
• Spheroidal graphite to BS 2789 Grade 420/12
• Separate rubber elements with a choice of grade and hardness with SM70 shore hardness being the standard.
• Rubber elements which are totally enclosed
and loaded in compression. |
