The S50PLRM0304 is a Neo-Flex coupling with a 3 mm bore on one side and a 4 mm bore on the other, designed for shaft-to-shaft torque transmission with torsional vibration isolation. It features 303 stainless steel hubs and a molded neoprene center with 73 durometer stiffness. The coupling accommodates a maximum angular offset of 8° and a lateral offset of 0.25 mm, with a maximum torque capacity of 65.1 N•m. Its overall length is 65.1 mm, its outer diameter is 17.5 mm, and it uses a set screw hub with a 2 mm set screw. The coupling is rated for ribbed smooth style misalignment compensation.
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.
