Construction Details
- Cast Iron to BS 17 grade
- Spheroidal graphite to BS 1563 Grade 400/15
- Separate rubber elements with a choice of grade and hardness with SM70 shore hardness being the standard
- Rubber elements are totally enclosed and loaded in compression
Benefits
- Ensures continuous operation of the driveline in the unlikely event of rubber damage
- Achieves low vibratory loads in the driveline components by selection of optimum stiffness characteristics
- With no lubrication or adjustment required, results in low running costs
- Avoids failure of the driveline under short circuit and other transient conditions
- Allows axial and radial misalignment between the driving and driven machines
- Eliminates torque amplifications through pre-compression of rubber elements
- The PCRB Coupling gives the lowest lifetime cost
