The A 5R 1-18 is a flexible coupling sleeve made of neoprene with a ground outer diameter, designed for use with zinc alloy die-cast hubs to accommodate angular misalignment up to 7.5° and lateral offset up to 0.040 inch. It operates to a maximum temperature of 250°F, requires no lubrication, provides electrical isolation, and dampens shock and vibration. The sleeve is used in conjunction with two hubs to form a complete coupling in the 1-18 series, with a maximum torque capacity of 16 lbf·in. and a maximum speed of 16800 rpm at 1750 rpm.
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.
