The Flexible Spline Coupling, part number A 5Z28-2508, features an overall length of 1.609 inches and accommodates 0.25-inch bores. It is constructed with a polyurethane spline and zinc alloy die-cast hubs for the 16, 20, and 25 series, while the 32 series utilizes sintered metal. This coupling allows for a maximum angular offset of 2 degrees and a lateral offset of 0.008 inches, making it suitable for applications requiring misalignment compensation. It operates effectively within a temperature range of -4¬8F to +140¬8F. The coupling is designed for high RPM applications, with a maximum rated RPM of 24,000. It is electrically isolated, dampens shock and vibration, and requires no lubrication, which can simplify maintenance. This product is ideal for engineers seeking a reliable coupling solution that can handle various load conditions and misalignments.
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.
