Flexible Couplings ( RB )

	General purpose, cost effective range which is manufactured in SG iron for torques up to 41 kNm.
	The Standard Range comprises • Shaft to shaft • Shaft to shaft with increased shaft engagement • 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	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.
