Safe torque transmission via REVOLEX pin & bush coupling
REVOLEX are torsionally flexible, fail-safe pin & bush couplings mainly used in applications with high torques and drives subjected to shocks. They are extremely solid, fail-safe, compensate for any kind of shaft displacement while transmitting the torque reliably.
The REVOLEX pin & bush couplings can be plugged in axially and are characterized by compact dimensions. These pin & bush couplings are generally equipped with hydraulically dismountable pins which means that special tools for disassembly are not required. The coupling components of the REVOLEX pin & bush couplings are maintenance-free and allow for smooth disassembly of elastomer rings along with pins when mounted.
REVOLEX pin & bush couplings are usually provided with 80 ShA NBR elastomer rings, the standard material being a true all-rounder. NR elastomers are available for cryogenic temperature applications. In addition backlash-free, electrically insulating NBR elastomers (blue coloured) are available. These are mainly used in cableway drives.
Small pin & bush couplings are relatively expensive, the REVOLEX commencing from a rated coupling torque of 4,300 Nm. The product ranges ROTEX and POLY-NORM are available for low performance ranges.
