The S51FCZM040040 is a rigid Fairloc® shaft coupling made of 303 stainless steel, designed to connect precisely aligned shafts for torque transmission. It has 4 mm bores on both sides, an overall length of 19 mm, and uses two M2.5 socket head cap screws for securing the hubs. The bores are concentric to within 0.025 mm T.I.R., and the coupling is rated for a maximum torque of 0.57 N·m. Socket head cap screws are supplied with the unit. The coupling requires shafts with g6, h6, or h7 tolerances for proper fit. The part is inted for use in precision applications where alignment is maintained and misalignment accommodation is not required.
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.
