The S58PY5MMJC0614 is a miniature ball coupling made of 303 stainless steel with a 6 mm bore and 33.3 mm overall length, designed to accommodate up to 15° angular misalignment, lateral offset, and axial motion while maintaining constant-velocity transmission. It features molybdenum disulfide and grease lubrication, low friction loss, a moment of inertia suitable for high-speed operation, and 1° to 2° backlash. Maximum torque capacity is 14.3 N·m at 5000 rpm under 11° to 15° angular misalignment. Axial motion capability is 1.8 mm, with lateral offset up to 4.2 mm. It uses a #10-32 set screw for shaft fixation. Four-ball-race variants are available for enhanced torque and smoother operation, though this model is not explicitly marked as such.
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.
