RBI

 

Renold Couplings’ new RBI coupling offers a general purpose, cost effective range, which is manufactured on SG iron for torques up to 60 kN.m. 

 

The standard range comprises:

  • Shaft to shaft
  • Shaft to shaft with increased shaft engagement

Applications:

  • Rubber processing and plastics industry
  • Fluid transmission industry
  • Material handling
  • Crane and hoists
  • Metal manufacture
  • Bulk handling
  • Pulp and paper industry
  • General purpose industrial applications

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
  • No lubrication or adjustment required, resulting in low maintenance 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 pre-compression of the rubber elements
  • Low lifetime costs

Features:

  • Intrinsically failsafe
  • Controls resonant torsional vibration
  • Maintenance free
  • Severe shockload protection
  • Misalignment capability
  • Zero backlash
  • Low cost

Construction details:

  • Spheroidal graphite to BS EN 1563:2011 Grade 400-15
  • Separate rubber elements with a standard SM80 shore hardness
  • Rubber elements which are totally enclosed and loaded in compression
