Splines offer novel coupling options

Splines and splined bushings offer an inexpensive and efficient way to transfer high transmission torques from shafts to gears, pulleys and other components, or to couple two shafts together.

An expanded series of splines and splined bushings from Stock Drive Products offer an inexpensive and efficient way to transfer high transmission torques from shafts to gears, pulleys and other components, or to couple two shafts together.

Additionally, because the splines permit sliding between mating members in the axial direction, by press-fitting a spline bushing into a component, such as a gear or belt pulley, the component can be shifted axially as desired even during rotation.

Such splined components can transmit much higher torques when retained by means of set screws or keyways.

The spline shafts are available in two series: the A 1C25 Series (manufactured of carbon steel C-12L14), and the A 1Y25 Series (stainless 416 annealed).

Shaft sizes range from 0.34375 to 0.75in diameter and shafts contain 16 (external) spline teeth.

Stock lengths of the splined shafts range from 1 to 6ft.

The splined bushings contain 16 internal teeth and are designated as the A 1C26 Series (manufactured of carbon steel C-12L14), and the A 1Y26 Series (stainless 416 annealed).

Their nominal bore diameters range from 0.34375 to 0.75in.

Bushing outer diameters range from 0.625 to 1.5in, and bushing lengths from 0.4 to 1.5in.
