Fenner Fenaflex Spacer Coupling Taper Lock F40 SM12 80, Max Bore 32mm, Torque 24 Nm, ATEX Approved SM12

Fenner SM12 Fenaflex Spacer Coupling Taper Lock F40 SM12 80 is an advanced coupling solution engineered for demanding industrial applications. This model features a robust Taper Lock design with a maximum bore size of 32 mm, ensuring versatile compatibility across various shaft diameters. The coupling delivers a nominal torque of 24 Nm, making it suitable for high-power transmission tasks in manufacturing, processing, and related environments.

With its ATEX approval, the Fenaflex Spacer Coupling is ideal for installations in environments where safety and compliance are paramount, including those with risk of explosive atmospheres. The product is designed for easy, time-saving installation, allowing motor and machine components to remain undisturbed when the tyre element is changed. The misalignment capability - up to 4 degrees angular, 6 mm parallel, and 8 mm axial - enhances equipment reliability, reduces stress, and supports flexible system layouts.

The internal cords are wound in both directions, enabling smooth operation even on reversing drives and further increasing durability. The coupling tyre is available in both standard and FRAS construction, catering to safety requirements in anti-static and fire-resistant scenarios. Maintenance is simplified by lubrication-free operation and straightforward visual inspection procedures.

Taper lock bush sizes are provided for both flange (1008) and spacer (1210) configurations, ensuring a secure fit and compatibility with industry-standard assemblies. With major dimensions such as A (104 mm), B (82 mm), C (118 mm), D (83 mm), and E (134 mm), this coupling meets technical installation specifications for precision applications. Distance between end shafts is 80 mm, making it suitable for various machinery setups.

Typical industrial use cases include power transmission in electronics, electrical machinery, and process equipment where precise alignment and robust design are required. This coupling is a preferred choice for sectors such as manufacturing, construction, HVAC, and laboratory instrumentation.

Max bore size of 32 mm accommodates a range of shaft diameters. Nominal torque rating of 24 Nm ensures reliable operation during high power loads. ATEX approved for compliance in hazardous conditions. Large misalignment tolerance supports flexible installations.

Bidirectional internal cords promote smooth function under reversing loads. FRAS construction available for fire-resistant anti-static requirements. Visual inspection reduces maintenance downtime.
