The S58PZ5-MJC1218 is a miniature ball coupling designed to accommodate angular misalignment up to 15°, axial motion, and lateral offset while maintaining constant velocity and low friction at high speeds. It features a 0.375 inch bore, 0.3125 inch length, 1.3125 inch closed length, and uses a #10-32 set screw. The center section is stainless steel, enabling higher torque capacity compared to nylon-center variants. It operates at a maximum torque of 1600 oz·in at 5000 rpm with up to 11°-15° angular misalignment and supports 0.05 inch lateral and 0.5 inch axial motion. Lubrication consists of molybdenum disulfide and grease.
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.
