The A 5Z 7-31414 is a flexible coupling with a 7/16-inch bore and an overall length of 2.0625 inches, designed to absorb angular and lateral misalignment, accommodate axial end play, and reduce bearing loads while operating up to 3600 rpm. It features steel hubs with zinc plating and a polyurethane body, offering zero backlash, quiet operation, and resistance to ozone, cuts, and tears. The coupling has an angular misalignment capacity of 15 degrees, a lateral offset capability of ±0.063 inch, and a maximum torque rating of 28 lbf·in. It uses a full-wraparound design with a precision swaged crimp and meets AGMA Class 2 bore tolerance.
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.
