Products
Gear racks, pinions, guideway racks, rollers and LM clamps for linear motion. Values below are typical ranges; the catalogue for each family gives exact sizes and ratings.
Pinions
Pinions matched to every rack module and tooth form, ready to mount on your motor or reducer output shaft.
Cylindrical (bore)Flange typeShaft pinionFelt lubrication
Guideway Racks
A gear rack and a running track in one bar. The ground guide edges carry rollers while the teeth drive the axis, so one part replaces a separate rack and linear guide on gantries, cutting tables and handling systems.

Roller Series
Sealed guide rollers that run on the edges of KJK guideway racks. Concentric and eccentric versions let you set the preload so the carriage runs smoothly with no play.
