KHK USA Inc., distributor of the KHK® brand of metric gears, announces its extensive line of metric gear racks, manufactured to the highest quality standards by Kohara Gear Industry Co., of Japan. KHK’s large selection of gear racks provide smooth transmission of power and are suitable for a very wide range of applications where linear translation is required.
KHK gear racks are offered in sizes from Module 0.5 through Module 10, with lengths from 100mm through 2000mm. All of the racks offered by KHK USA have finished ends which permit the joining of various lengths of gear rack to form one continuous length.
The list of available materials for KHK gear racks includes brass, carbon steel (S45C), chromalloy steel (SCM440), stainless steel (SUS303), and engineering plastics such as MC901 nylon.
The 360 configurations of KHK gear racks include rectangular cross section, square cross section and round cross section with either straight or helical teeth. These gear racks can be supplied with modifications including the addition of tapped or through holes, hardening of the teeth and shortening of the length. KHK USA J-Series products, which have already had many of these modifications completed, are available with quick lead times.
Unique to KHK is a laser hardening process for gear racks. This process allows for the hardness of the rack tooth flank to be similar to that of an induction hardened or flame hardened rack, without the introduction of any distortion. These gears racks are identified in the KHK catalog by a suffix of HL.
