The S50MFBMA32H10H12 is a split hub type bellows coupling with aluminum alloy hubs and a phosphor bronze bellows, designed for zero backlash and maintenance-free operation in metric applications. It has bore diameters of 10 mm and 12 mm, an overall length of 42 mm, and a maximum torque rating of 4 N·m. The coupling supports up to 0.2 mm parallel offset and ±2.5 mm axial misalignment, with a torsional stiffness of 330 N·m/rad and a maximum rotational speed of 4800 rpm. The static max torque is 2 N·m, and the rotational inertia is 9.6 × 10⁻⁶ kg·m². The coupling weighs 58 grams with maximum bore diameters.
Couplings Types
Couplings can be divided into two categories: flexible and rigid. Both types are used to connect two rotating shafts driven by a motor and transmit torque and angular velocity; however, flexible couplings and shafts are designed to accommodate angular misalignment, angular offset, axial movement, and a variety of load conditions. A flexible coupling is pliable due to the twisting and compression of a durable, adaptable material, like neoprene, rubber, or silicone.
Flexibility can also be achieved with thin metal disks, corrugated aluminum bellows (bellows couplings), or even a stainless-steel ball (miniature ball couplings). Some materials can provide vibration reduction, as in our precision flexible antivibration couplings.
Rigid couplings are limited by comparison; rigid couplings are used when shafts are already positioned in precise lateral and angular alignment. Their rigid design inhibits shaft misalignment. They can generally transmit more power than flexible couplings due to their rigidity.
Even the most complicated application challenges can be solved by our skilled engineers, they will identify the best coupling solution for your application. SDP/SI provides a comprehensive range of rigid and flexible couplings. Many of our precision couplings, including the Miniature Bellows Coupling and the Neo-Flex Coupling, have our patented Fairloc® Hub design, which solves phasing, timing, positioning, and frequent removal problems.
