7N-7295: 19mm Long Internal Spline Coupling

An Internal Spline Coupling is used to connect two shafts while allowing for a certain degree of alignment and axial movement. The Internal Spline is a series of ridges or teeth that fit into corresponding grooves or spaces on the external Spline of the other part. Attributes: • Hardened to Rockwell hardness of 30N 73 HRC minimum, which determines it's resistant to deformation and wear • Withstands the high pressures and forces Applications: An Internal Spline Coupling is used to transmit torque from one shaft to another.
