SMI (Sino Machine Industry) serving the industrial markets of the world.
A power take-off (PTO) shaft transmits engine power from a tractor or vehicle to an attached implement or driven machine. It is one of the most fundamental mechanical interfaces in agricultural equipment — standardised in dimensions and operating speed to allow interchangeability across tractor and implement brands worldwide.
SMI manufactures PTO shafts, yokes, safety shields and associated driveline components to customer drawing and specification. Production covers casting, machining, surface treatment and export packaging — with finished assemblies supplied to agricultural equipment manufacturers and distributors in Europe and other global markets, including supply to customers in Germany.
Agricultural PTO shafts are standardised under ISO 500, which defines shaft dimensions, spline profiles, operating speeds and safety requirements. Three principal configurations are in common use:
| Type | Speed | Splines | Shaft Diameter | Application |
|---|---|---|---|---|
| Standard | 540 RPM | 6 | 1⅜ inch | General agricultural implements |
| High speed — small | 1000 RPM | 21 | 1⅜ inch | Higher power applications |
| High speed — large | 1000 RPM | 20 | 1¾ inch | High torque applications |
SMI can manufacture to any of these standard configurations or to customer-specified non-standard profiles. Spline dimensions, shaft length, yoke type and safety shield configuration are all customisable to the specific implement or equipment requirement.
Complete PTO shaft assemblies comprising inner and outer telescoping tubes, universal joints, yokes and safety shields. Shaft length, tube diameter, joint angle capacity and safety shield type are specified to the customer’s implement design. Standard yellow finish or alternative surface treatments available.
Cast and forged yoke components in standard and custom configurations — including push-pin, bolt-on and quick-release locking types. Spline bore dimensions manufactured to ISO 500 or customer specification. Available in standard silver/natural finish or painted to customer colour requirement.
Plastic safety shields for PTO shaft assemblies — manufactured to ISO 500 safety requirements. Standard black configuration or custom colour. Shield geometry designed to the specific shaft assembly dimensions.
Individual universal joints, cross kits, bearing cups and yoke components available as spare parts supply alongside complete shaft assemblies. All parts manufactured to the same drawing and specification as the original assembly.
The gallery images above show SMI’s PTO shaft production and export preparation process — from painted shaft assemblies on the production line through to completed export packaging. Key manufacturing stages include:
Finished assemblies are manufactured in China and exported globally. SMI’s production capability supports both small development orders and large-volume OEM supply programmes.
