The S5911YMJRM1408 is a three-piece junior coupling with an 8 mm bore, made of chemical-resistant nylon, designed for torque transmission without lubrication. It operates at speeds up to 6000 rpm and within a temperature range of -25°C to +100°C. The coupling is electrically isolated and features a crowned gear tooth design. Its overall length is 50 mm, outside diameter is 40 mm, and it includes a keyway with dimensions w=2 mm and t=1 mm. A set-screw is provided opposite the keyway. The part is metric and complies with the BoWex® JRM-14 series specifications.
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.
