KGC1-22 is a gear coupling inner hub with a module of 2, 22 teeth, and a 10 mm bore, constructed from S45C steel with induction-hardened gear teeth achieving 50-60 HRC hardness. It features a standard full-depth tooth profile with a 20° pressure angle and a keyway dimension of 7 mm width × 3 mm depth, conforming to JIS B1301 Js9 tolerance. The allowable torque is 98.1 N·m (10.0 kgf·m), determined by keyway shear strength at 49 MPa. Total length is 73 mm, and weight is 0.35 kg. The hub includes a set screw and is designed for use with a C-shaped snap ring groove. Secondary operations on the tooth area 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.
