The A 5R28-16 is a spline element for a flexible coupling, designed to connect two shafts while compensating for up to 2° of angular misalignment and 0.008 inches of lateral offset. It is made of polyurethane and operates between -4°F and +140°F. The coupling series provides electrical isolation, dampens shock and vibration, and requires no lubrication. It supports a maximum torque of 4.4 lbf·in and operates at up to 24,000 rpm. The spline is used with zinc alloy die-cast hubs of the 16 series and fits a bore diameter range up to 0.315 inch. The part is electrically isolated, maintains performance without lubrication, and is rated for high-speed applications.
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.
