The S50PMRM0204 is a miniature neoprene coupling with 2 mm and 4 mm bore sizes, designed for torsional vibration isolation between shafts. It features 303 stainless steel hubs and a molded neoprene center, with a maximum torque capacity of 0.71 N•m, angular misalignment tolerance of ±2°, lateral offset of ±0.05 mm, and axial motion of ±0.1 mm. The coupling has an overall length of 23.6 mm and is secured by set screws. Service factors for shock, non-uniform, and uniform loads are 3, 2, and 1.5 respectively, guiding torque selection for application 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.
