Fenner Fenaflex Tyre Coupling with B Flange Pilot Bore F80

Fenner's Fenaflex Tyre Coupling with B Flange Pilot Bore F80 is engineered for precision in mechanical power transmission. This coupling is designed to link two shafts and compensate for misalignments, making it vital in industrial and engineering machinery installations.

The F80 model features a robust construction with 6 pins, supporting secure and dependable shaft connections. It accommodates a maximum bore diameter of 65 mm and a minimum of 25.4 mm, allowing it to fit various shaft sizes common in mechanical setups. Key dimensions, including E (51 mm), D (95 mm), M (47 mm), and F (53 mm), offer compatibility with a wide range of industrial drives.

The internal load-carrying cords are wound in both directions, ensuring the coupling delivers reliable operation, even in applications with reversing drives. Its tyre element is available in standard and Fire Resistant Anti Static (FRAS) construction for added protection and compliance with safety standards. With the ATEX approval, the coupling is suitable for hazardous environments where extra safety is required.

This model allows for large misalignment capabilities: up to 4 degrees angular, 6 mm parallel, and 8 mm axial, enabling more flexible machine layouts. Installation is quick and simple, as the coupling can be maintained or tyre replacements can be performed without disturbing the connected motor or machine. Lubrication-free operation further reduces maintenance downtime, while simple visual inspection assists in routine checks and preventive maintenance tasks.

Fenner’s F80 coupling is supplied as a complete unit with B flange, pilot bore, and all necessary pins for immediate deployment in couplings, collars, and adapter assemblies. Common use cases include heavy-duty transmission equipment, pumps, conveyors, compressors, engineering/industrial drives, and hazardous locations requiring robust, compliant couplings.

This product is ideal for industrial, mechanical, and plant maintenance applications. Explore more high-performance industrial couplings and Fenner solutions in our Mechanical Coupling category to ensure your operations are both efficient and reliable.
