The S50MFBMS20P06P06 is a set screw type bellows coupling with 6 mm bores on both ends, made entirely of stainless steel, designed for zero backlash and maintenance-free torque transmission in precision applications. It has an overall length of 32 mm, a maximum torsional torque rating of 1.5 N·m, and a static torque capacity of 3 N·m. The coupling supports a maximum angular misalignment of 2 degrees, a parallel offset of 0.15 mm, and an axial misalignment of +0.6/-1.8 mm, with a rated speed of 19,000 rpm and a mass of 37 grams. The torsional stiffness is 220 N·m/rad and the moment of inertia is 2.3 × 10⁻⁶ kg·m² under maximum bore conditions.
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.
