Overview
ISO 5711:1995 - "Tractors and machinery for agriculture and forestry - Wheel-to-hub fixing dimensions" specifies dimensional requirements for attaching wheels to hubs on tractors and agricultural and forestry machinery. The standard defines wheel-to-hub interface geometry (study circle, stud holes, central bore, bearing and centring diameters) and presents recommended forms of attachment. It clarifies that specified dimensions do not guarantee interchangeability between different vehicles.
Key topics and technical requirements
Applications and who uses it
ISO 5711:1995 is intended for:
- Wheel and hub designers and OEM engineers creating tractor and forestry machinery wheel interfaces.
- Manufacturers of wheels, hubs, studs and nuts who require standardised fixing dimensions.
- Maintenance, inspection and aftermarket service teams performing wheel replacements, retrofits or compatibility checks.
- Procurement and quality assurance teams specifying interface dimensions in technical procurement documents.
Practical uses include design validation, manufacturing tolerances, spare‑parts specification, and ensuring safe wheel mounting and centring on agricultural and forestry vehicles.
