The A 5D28-2012 is a coupling hub from the 5D28-20 Series by Stock Drive Products & Sterling Instrument - SDP/SI. It features a polyurethane spline and a zinc alloy die-cast hub, designed for high RPM applications. The coupling allows for different bore sizes on opposite sides, providing flexibility in assembly. It can accommodate a maximum angular offset of 2¬8 and a lateral offset of 0.008 inches, making it suitable for applications requiring misalignment compensation. The operating temperature range is from -4¬8F to +140¬8F. This coupling does not require lubrication and is electrically isolated, which can be beneficial in various engineering applications. The rated torque for this series is 8.8 lbf in, and it is capable of handling up to 19,000 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.
