Kerk Motion Products Introduces New Spline Shaft Series


Kerk Motion Products, one of the world's premier manufacturers of non-ball lead screws, announces the introduction of its new Spline Shaft series. The Kerk Spline Shaft series has been designed for light load applications, where low cost, low friction and long life are critical design considerations. This includes any application that requires a rotary drive with adjustable position or a linear guide with high torsional stability.

Depending on the particular application, a Kerk spline shaft can offer a wide range of benefits. In an application currently using a ball spline, hex-, square- or D-shaft, it can provide a lower cost alternative without sacrificing positional accuracy. Because of its low-friction performance, it can allow a user to downsize certain process equipment, including motors, reducing heat buildup and energy requirements. Ultimately, its low friction performance will also contribute to longer product life.

The assembly consists of a lightweight, aluminum spline shaft treated with Kerk's proprietary, low-friction TFE coating, coupled with a graphite and PTFE-filled thermoplastic bushing. The TFE coating eliminates the need for external lubrication and maintenance. The bushing is manufactured with an integral brass collar to facilitate mounting configurations without nut distortion.

Spline shafts are available with any combination of the following standard features: basic or anti-backlash bushing, plain or thread mount bushing, and 1/4", 3/8" or 1/2" diameter shaft. Custom machining of both the bushing and rail is available for mounting considerations or to adapt to any required format. Standard lengths up to 24" are offered. Hollow configurations and lengths up to 96" are also available on a custom basis.
