Shaft Types

Custom Shaft Types We Machine

Select the shaft structure from its motion, load, assembly space, and mating components.

Custom straight shaft

Straight Shaft

Simple support or drive shaft with controlled diameters and end details.

Custom motor shaft

Motor Shaft

Journals, keyways, threads, and rotor interfaces built around the assembly.

Custom spline shaft

Spline Shaft

Multiple teeth transfer torque while controlling fit, alignment, and axial movement.

Custom stepped shaft

Stepped Shaft

Multiple diameters create bearing seats, shoulders, and precise component locations.

Bearing journal, shoulder, keyway, threaded end, spline and hole shaft features

Functional Features

Custom Features Machined to Your Assembly

We control the surfaces that locate components, transfer torque, retain parts, and support rotation.

Bearing journalsControlled fits for stable rotation and bearing support.
ShouldersPositive axial location for mounted components.
Keyways and splinesReliable torque transfer to hubs, gears, and couplings.
Threads and holesFastening, lubrication, sensors, pins, or secondary connections.

Machining Process

How We Machine Custom Shafts

CNC turning establishes the main axis and diameters. Secondary machining, treatment, grinding, and inspection complete the specified features and performance.

1Drawing reviewConfirm datums, fits, critical surfaces, material, and inspection needs.
2Material setupMatch bar, tube, forging, or prepared blank to the part and quantity.
3CNC turningEstablish the axis, journals, diameters, shoulders, faces, and profiles.
4Feature machiningMachine keyways, splines, flats, threads, holes, grooves, and end details.
5Treatment and finishApply heat treatment, coating, or grinding only where the specification requires it.
6Inspection and packingVerify functional dimensions and protect finished surfaces for shipment.

Material Selection

Metal and Plastic Options for Custom Shafts

Choose the material by load, wear, corrosion, temperature, weight, dimensional stability, and required finishing.

Carbon Steel

A strong, economical choice for general shafts, motor shafts, pins, spacers, and transmission components.

Key properties
Strong, machinable, cost-effective
Common grades
1018, 1045, AISI 1060
Typical colors
Natural gray; black or zinc-colored after finishing
Surface / finish
Black oxide, zinc plating, tempering, induction hardening, grinding

Modified-plastic machining and test-sample services are available for stricter wear, temperature, strength, electrical, and chemical environments.

Production Control

Custom Shaft Quality and Delivery Control

Before production, we lock the material, datum strategy, machining route, critical checks, finish, and packing requirements.

Drawing firstIdentify the dimensions and surfaces that control assembly.
Process matchedUse turning, milling, grinding, and finishing only where required.
Critical checksMeasure functional features during production and final inspection.
Protected shipmentClean, identify, and protect finished shafts before dispatch.

FAQ

Custom Shaft Machining Questions

What should I send for a quotation?

Send a 2D drawing or 3D model, material, quantity, tolerances, finish, and required inspection points.

When does a shaft need grinding?

Grinding is used when journal fit, roundness, runout, or surface finish exceeds normal turning capability.

When should I specify a spline shaft?

Specify splines for multi-tooth torque transfer, accurate centering, or controlled axial sliding.

How do you protect the delivery schedule?

Material availability, setups, outside treatments, inspection points, and packing are confirmed before the production date is committed.
