ANSI B92.1 Spline Shafts
These splines are found in the industrial, agricultural, hydraulic, and some automotive applications. These shafts allow for higher RPM during operations with minimum backlash. These splines can be found in higher RPM PTO shafts and high load hydraulic pump and motor shafts. These splines are all measured in imperial units and more common in North American manufactures and industries.
