Product Questions & Answers (1)

Question by: Dustin M on Aug 23, 2025, 2:40 PM
got a splined shaft question - is this 14 tooth SAE C gonna work with standard SAE C equipment or is there something special about the spline count
Answer by: Customer Support on Aug 24, 2025, 4:43 PM
Standard SAE C splined shafts typically use 14 teeth, so your existing SAE C equipment should mate up properly with this motor. The 14T configuration follows the standard SAE specifications for that flange size, meaning pulleys, couplers, and other driven components designed for SAE C should connect without issues.
