KHK USA Inc. (Mineola, NY), a factory owned distributor of the KHK brand of metric gears, announces its extensive line of metric spur gears which are offered with several types of locking hubs. Over 8,000 configurations of off-the-shelf KHK Spur Gears are available in many materials, configurations, modules and numbers of teeth. Specifically:

  • KHK’s SS Series Spur Gears are minimum plain bore spur gears made from 1045 carbon steel. The “F series version of these gears includes a tapered bore locking hub which is preassembled for ease of use. These gears are available in pitch sizes Module 0.5 through Module 10 with 12 to 200 teeth and are designed for use in general industrial automation applications.
  • KHK’s SSA Series Spur Gears are hubless versions of the SS series and are available in Modules 1 through 6 with 15 to 200 teeth. These gears are also available with the “F” series tapered locking hub.
  • KHK’s SSG Series Spur Gears are similar to the SS series with the addition of the tooth surfaces being induction hardened to HRC 50-55 for added durability. After heat treating these gears have their teeth ground finished for higher precision. The “F” series taper locking hub option is available for these gears in addition to the “E” series keyless locking hub. The “E” series hub is preassembled with the SSG gear and will lock onto the shaft with one twist of the locking screw. 

With these locking hub options, KHK spur gears are ready to use and are easy to install. There is no reworking of the bore required by the end user and the hubs allow for easy disassembly when needed.
