Frequently Asked Questions

Motor shafts include solid shafts, hollow shafts, stepped shafts, and splined shafts. Each type is designed for specific motor applications, load requirements, and mounting configurations. Solid shafts are most common for standard applications.

A motor shaft is the rotating component that transfers mechanical power from the motor to the driven equipment. It connects the motor's rotor to external loads and must withstand torque, bending moments, and axial loads while maintaining precise alignment.

In engines, there are typically crankshafts (which convert reciprocating motion to rotary motion) and camshafts (which control valve timing). Both are precision-engineered components critical to engine performance and reliability.

Motor shafts are typically made from carbon steels (1018, 1045), alloy steels (4140, 4340), or stainless steels (303, 304, 316). Material selection depends on load requirements, operating environment, and cost considerations.

We ensure motor shaft quality through precision machining, dimensional verification, surface finish control, material certification, and performance testing. Our process maintains consistent quality for high-volume production.

Yes, Partsproto offers custom motor shaft design and manufacturing services. We can produce motor shafts with specific dimensions, materials, and surface treatments to meet your exact motor application requirements.

Standard motor shafts typically have lead times of 1-3 weeks for high-volume orders. Custom motor shafts may take 2-4 weeks depending on complexity and quantity. We offer quick turnaround for standard configurations.
