Start with how the spline must mate, load and locate
Reliable spline shaft selection begins with the mating geometry rather than a generic diameter. The product range covers external splines, an internal spline configuration and an integrated gear-and-spline shaft, with available technical data presented alongside the drawing inputs needed to finalize geometry and fit.
GeometryModule or pitch, tooth count, pressure angle and mating form.
Material conditionBase material, heat treatment and hardness requirements.
DatumsBearing seats, shoulders and concentricity relationships.
InspectionFit, runout, hardness, surface finish and required records.
Product architecture
Four spline-shaft families for custom power-transmission interfaces
Browse by interface type first, then compare material, heat treatment and available geometry within each family.
External Spline Shafts
External tooth forms for mating hubs, gears and driveline interfaces.

Application context
Match the interface to the duty, not just the nominal size
Agricultural drivetrains, gearbox connections and general transmission systems impose different shock, alignment, lubrication and service-access requirements.
Agricultural driveline interfaces
Check shock loading, contamination, service cycles and mating geometry before specifying the shaft.
Gearbox spline connections
Review concentricity, bearing-seat datums, lubrication and whether the spline is fixed or sliding.
Integrated drivetrain interfaces
Define torque path, axial restraint, assembly access and inspection requirements across the connection.
Manufacturing logic
Process choices follow geometry, material and inspection needs
Manufacturing routes are selected to match the drawing, material condition, hardness, geometry, inspection requirements and production quantity.
Datum and turning preparation
Establish reference surfaces and concentric features before the spline operation when the drawing requires them.
Spline generation
Milling, hobbing, shaping, broaching, rolling or grinding may be selected according to the actual tooth form and production route.
Heat-treatment planning
Sequence machining and heat treatment around distortion risk, hardness depth and final finishing requirements.
Inspection against functional datums
Verify the dimensions and relationships that determine assembly performance, not an isolated checklist.
RFQ preparation
Six inputs that make a spline shaft enquiry actionable
A drawing is the best starting point. When a complete drawing is not available, provide the functional information below so open items can be identified instead of guessed.
- Mating spline geometryExternal/internal form, tooth count, module or pitch, pressure angle and fit requirement.
- Overall shaft geometryCritical diameters, lengths, shoulders, grooves, threads and bearing seats.
- Material and heat treatmentGrade, hardness requirement, case/core condition and any finish machining after treatment.
- Duty informationTorque, speed, shock loading, reversing, sliding motion and operating environment.
- Datum and tolerance schemeConcentricity, runout, axial location and the features that control assembly.
- Inspection and quantityRequired reports, gauges or measurement records plus prototype and production quantities.
