The S59DZ9-CF120410 is a constant-velocity coupling designed to reduce rotational vibration and transmit torque with zero backlash, using aluminum hubs, an acetal control-flex member, and hardened alloy steel pins. It has a 0.250 inch bore, 0.620 inch hub length, and 0.374 inch overall width, with a maximum outer diameter of 0.748 inch. Rated for continuous torque of 144 ozf-in and peak torque of 208 ozf-in, it supports a maximum angular misalignment of 1.5° and operates within a temperature range of -10°F to +150°F. The coupling requires no maintenance or lubrication and provides electrical isolation.
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.
