2. Characteristics of Rathi Flexible Couplings RBW
– Manufacturer brand: Rathi-Ringfeder/India.
– The Rathi-Ringfeder Flexible Couplings RBW is a sleeve-type elastomer coupling designed to transmit torque smoothly while absorbing vibration and compensating for shaft misalignment in industrial drive systems. With its reliable sleeve flex coupling RBW design, this coupling provides clean operation, easy installation and long service life.
Key features
+ Flexible elastomer sleeve design: The rathi flexible coupling RBW uses an elastomer sleeve element that allows smooth torque transmission while reducing vibration and shock loads in the drive system.
+ Quick and easy installation: The sleeve flex coupling RBW can be installed rapidly because it does not require bolts, gaskets, covers or seals, making assembly simple and efficient.
+ No lubrication required: The rathi flexible coupling RBW operates without lubrication, eliminating the need for grease or oil maintenance during operation.
+ Maintenance-free operation: Thanks to its elastomer sleeve construction, the rathi flexible coupling RBW minimizes wear and does not require regular maintenance.
+ Smooth and reliable power transmission: The teeth of the elastomer sleeve lock into the flange teeth without clamps or screws, allowing the rathi flexible coupling RBW to transmit torque smoothly under load.
+ No metal-to-rubber rubbing action: The design of the sleeve flex coupling RBW prevents metal-to-rubber friction, reducing wear and extending service life.
+ Resistant to dirt, abrasives and moisture: The rathi flexible coupling RBW performs reliably even in dusty or humid industrial environments.
+ Easy shaft alignment inspection: Alignment of the rathi flexible coupling RBW can be checked easily with a straight edge placed across the precision-machined flanges.
+ Clean and quiet operation: The elastomer design ensures low noise and smooth performance in industrial machinery.
+ Basic specifications: Capacity: 14 kW @ 100 rpm. Maximum bore: 100 mm
