The S50MFBMA20H06H06 is a split hub type bellows coupling with aluminum alloy hubs and a phosphor bronze bellows, designed for zero backlash, maintenance-free torque transmission between shafts. It has 6 mm bores on both sides and an overall length of 32 mm. The coupling supports a maximum torque of 0.8 N·m and a static torque of 1.6 N·m, with a maximum rotational speed of 7700 rpm. It has a torsional inertia of 1 × 10⁻⁶ kg·m² and a torsional stiffness of 180 N·m/rad. The coupling permits a maximum parallel offset of 0.15 mm, angular misalignment of 2°, and axial movement of +0.6/-1.8 mm. Its weight is 16 grams when configured with the maximum bore diameter.
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.
