KGC1-25 is a gear coupling inner hub with a module of 2, 25 teeth, a 25 mm bore, and an outside diameter of 54 mm. It features standard full-depth gear teeth with a 20° pressure angle, and the material is S45C with induction-hardened tooth surfaces achieving 50-60 HRC hardness. The coupling has a face width of 10 mm and a hub width of 25 mm. Allowable torque is 137 N•m (14.0 kgf•m), determined by keyway shear strength. A set screw and C-shaped snap ring groove are included. Keyway dimensions are 7 mm width by 3 mm depth, conforming to JIS B1301 standards with Js9 tolerance. Weight is 0.32 kg. Secondary operations on gear teeth are prohibited due to induction hardening.

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.
