The S50MFBMS12P04P06 is a set screw type bellows coupling with 4 mm and 6 mm bore diameters, made entirely of stainless steel, designed for zero backlash and maintenance-free operation. It has an overall length of 23.5 mm and is rated for a maximum torsional torque of 0.5 N·m and a static torque of 1 N·m. The coupling supports a maximum speed of 32,000 rpm, an angular misalignment of up to 1.5 degrees, a parallel offset of 0.1 mm, and an axial offset of +0.4/-1.2 mm. Its torsional stiffness is 100 N·m/rad, and it weighs 9.1 grams with the maximum bore sizes. The coupling complies with ISO projection standards for bore and shaft dimensions.
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.
