A new Series of gear couplings from Quality Transmission Components (QTC) feature induction hardened gear teeth as an ideal solution to the precision coupling of two shafts. These couplings, identified as the GC... Series are stocked in carbon steel hardened to HRC 48-53. The gear teeth on the inner hubs are crowned to allow for up to 5O of shaft angle offset. Due to the induction hardening of the gear teeth, these couplings have excellent durability. All surfaces are Unichromic plated. These units are machined complete with keyways, set screw holes, and finished bores and are ready for immediate installation. These gear couplings are produced by KHK Co. Ltd. under an exclusive distribution arrangement with QTC in the US. They are featured at the QTC eStore where you can order online, request a quote, download CAD models, check stock plus view catalog specifications and technical pages. Other power transmission solutions provided by QTC include over 7,000 off-the-shelf gears including spur, helical, miter, bevel, internal, rack, gear couplings, spline shafts, gearboxes, and other components for prototypes and production applications.
