S55SS7MFSH33125 is a flexible shaft assembly with a 3.3 mm diameter stainless steel cable and an M2 end fitting, designed for torque transmission in remote control applications. It has a shaft length of 125 mm and supports a maximum operating torque of 1.69 N·m under manual operation and 0.99 N·m under dynamic operation. The shaft permits a radius of curvature of 3.8 mm and an input deflection rate of 7 degrees per 30 cm when winding and 10 degrees per 30 cm when unwinding. Both the cable and end fittings are made of stainless steel. This part is part of a series designated for metric flexible shafts with specified end fittings and lengths.
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.
