Pin-and-buffer elastic coupling. Evolution of the RN-Flex with reinforced pins for high-torque applications. Compatible with large Neupex sizes.
The RB-Flex pushes the RN-Flex logic towards very high torque capacities.
The reinforced pins of the RB-Flex allow the transmission of torques higher than the standard RN-Flex. Suited to mills, crushers, compressors, presses and other high-torque applications.
The RB-Flex covers the large sizes of pin-and-buffer couplings. Compatible with high-capacity Flender Neupex references.
Retains the operational advantages of the RN-Flex: radial buffer removal, tolerance to misalignment, damping via NBR buffers.

The complete reference table (nominal torques, bores, dimensions, speeds) is available in the manufacturer's technical PDF datasheet. Download it below or ask us for a custom summary based on your application.
All sizes, dimensions, materials and torques available in the manufacturer's documentation.
The RB-Flex pin-and-buffer elastic coupling is the high-capacity evolution of the RN-Flex. The steel pins are reinforced and heat-treated to enable the transmission of significantly higher torques.
The RB-Flex is suited to heavy-duty industrial applications: mills, crushers, compressors, hydraulic presses, mixers. It retains interchangeability with the Flender Neupex standard for large sizes and the availability of spare parts (NBR buffers in particular).
The operational advantages of the RN-Flex are preserved: radial buffer removal without shaft movement, tolerance to angular, parallel and axial misalignment, damping of shocks and vibrations thanks to the nitrile rubber buffers.
