The S51FCZM080120 is a rigid Fairloc® shaft coupling with 8 mm and 12 mm bores and an overall length of 30 mm, made of 303 stainless steel. It uses M4 socket head cap screws and has a maximum torque rating of 15.1 N·m. The bore diameters are concentric to within 0.025 mm T.I.R., and the coupling is designed for precise shaft alignment with suggested shaft tolerances of h6, h7, or g6. The part includes integral socket head cap screws and a nonmarring design. The coupling is 30 mm in length, with bore diameters of 8 mm and 12 mm, and a hub diameter of 26 mm on both sides.
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.
