The S50MFBMA32H10H10 is a split hub bellows coupling with aluminum alloy hubs, a phosphor bronze bellows, and steel cap screws with a black oxide finish, designed for zero backlash and maintenance-free operation. It has 10 mm bores on both ends and an overall length of 42 mm. The coupling handles a maximum torque of 2 N•m and a static torque of 4 N•m, with a maximum rotational speed of 4800 rpm. It provides an angular misalignment tolerance of 2°, parallel offset of 0.2 mm, axial play of +0.8/-2.5 mm, and torsional stiffness of 330 N•m/rad. The rated moment of inertia is 9.6 × 10⁻⁶ kg•m², and the weight is 58 grams 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.
