159-6 Arpex ARN-6 NEN coupling

Flender's N-ARPEX couplings represent a state-of-the-art design that combines a high power-to-weight ratio with an excellent price-performance ratio. N-ARPEX couplings are all-steel multi-plate couplings designed for industrial applications that require high performance and reliability without compromising on durability or ease of use. N-ARPEX is specifically designed for high torques and demanding conditions. This makes it the ideal choice for applications such as compressors, generators, pumps and turbine drives. In addition, the coupling's multi-plates allow for the compensation of small misalignments, which protects the equipment and bearings from excessive stress. N-ARPEX couplings are completely maintenance-free, which reduces operating costs and maintenance time. Thanks to the intermediate tube design of N-ARPEX couplings, they also work for longer shaft end distances. Standardized lengths are available as standard.

Benefits of the N-ARPEX series:
• Optimized discs enable power transmission at very high torques and speeds and compensation of small misalignments.
• Comparatively low weight reduces bearing loads.
• Provides a durable and maintenance-free coupling solution that optimizes the operation of the equipment and minimizes the need for maintenance.
• Various size and design options for a wide range of applications.
• Easy installation and disc replacement.
• Suitable for use in potentially explosive environments, certified 2014/34/EU (ATEX).
