2. Characteristics of Ringfeder Elastomer Rings TNB:
– Elastomer Rings TNB manufactured by Ringfeder/Germany
– Made of butadiene-nitrile rubber (Pb82) or polyurethane (VkR, VkW).
– The black (Pb82) buffer of the TNB Spider is typically conductive, thereby preventing unwanted static electric charges.
– The red (VkR) and white (VkW) buffers ensure insulation between connected machinery as long as there are no other conductive connections.
– Material properties: Shore hardness is specified for each type, showing elasticity and recovery.
– Damping ability:
+ Absorbs vibrations, limits resonance when the machine operates through the dangerous speed range.
+ Protects machinery from damage due to shock and torque overload.
+ Quickly reduces oscillations after impact, thanks to the material’s damping properties.
+ Contributes to reducing transmission noise, providing smooth operation.
