Rolled splines represent an efficient plastic forming process. By applying radial or tangential rolling pressure to shaft components using carbide or alloy steel rollers, spline teeth are formed through extrusion at ambient temperatures. This method offers high material utilization and rapid processing efficiency, making it particularly suitable for medium to large scale production runs.
Application Fields:
Automotive drive shafts, transmission input/output shafts
Constant velocity (CV) joint splined shafts
Construction machinery drive shafts
Motor shafts, pump shafts, gear shafts
Suitable Materials:
Medium-carbon steel: 45#
Alloy steel: 40Cr, 42CrMo, 20CrMnTi (processed prior to quenching and tempering or carburizing)

Cold formed for high tooth root strength
Cold forming processes allow continuous metal flow along tooth profiles, significantly enhancing root strength and fatigue resistance compared to machined splines.
Consistent tooth geometry and stable precision
Formed in a single pass using a roller die, it achieves high consistency in pitch, tooth profile, and symmetry. Ideal for mass production, it offers advantages for transmission components requiring high assembly precision.
