• Flywheel to shaft
• Flywheel to shaft with increased shaft engagement

Applications

• Generator sets
• Pump sets
• Compressors
• Wind turbines
• Metal manufacture
• Bulk handling
• Pulp and paper industry
• General purpose industrial applications

Features

• Intrinsically fail safe
• Control of resonant torsional vibration
• Maintenance free
• Severe shock load protection
• Misalignment capability
• Zero backlash
• Low cost

Benefits

• Ensuring continuous operation of the driveline in the unlikely event of rubber damage.
• Achieving low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
• With no lubrication or adjustment required resulting in low running costs
• Avoiding failure of the driveline under short circuit and other transient conditions.
• Allows axial and radial misalignment between the driving and driven machines.
• Eliminating torque amplifications through precompression of the rubber elements.
• 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
