R-Type Chamfer for Stress Reduction in Shaft Couplings
This flexible shaft coupling features an R-type chamfer at the cut seam to reduce sharp internal corners. This helps lower the risk of stress concentration in areas subject to frequent torque changes.
The R-radius fillet allows for more even load distribution during use. Suitable for applications such as CNC equipment, stepper motors, and servo systems, where precision shaft coupling performance is important.
