The Module 2, 40 Tooth, 30mm Bore, Mild Steel Gear Coupling Inner Hub (part number KGC2-30) is designed for effective power transmission between rotating shafts. It features standard full depth gear teeth with a pressure angle of 20¬8, providing reliable engagement and torque transfer. The inner hub is constructed from S45C mild steel and undergoes induction hardening, resulting in a tooth hardness of 50 to 60 HRC, which enhances durability and wear resistance. The product is treated with trivalent chromate for corrosion resistance, ensuring longevity in various operating environments. The inner hub is compatible with a bore size of 30mm and is designed to accommodate up to 5¬8 of angular misalignment due to its crowned gear teeth. It is ready for immediate installation, as it comes machined with keyways and set screw holes. This gear coupling inner hub is suitable for applications requiring robust coupling solutions in mechanical systems.

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.
