Inquiry (采购产品): Spline Shaft Hello, I'm looking to get a bit more information on splined shaft product number 0411 so we could make a mating internal spline. We will be using it to make a part for a downhole oil field tool. If I can get answers to these questions that would be great: 1. What is the Pressure Angle? 2. The Material I'm looking at is 4140 but we will be running the tool in H2S so we need max hardness of HRC22, We can temper back if we can get significant cost savings through this route. 3. Is this a metric series spline? If so what Module? 4. Is the Nominal size equal to the Pitch Diameter? 5. Can I get a quote on that as well?
