Claim:
A rotor for a rotorcraft having foldable hinged blades, the rotor comprising a hub ( 10 ), each blade being connected to the hub by a sleeve, each sleeve being hinged about a pitch axis ( 15 ) relative to the hub, the rotor including a lag damper ( 14 ) associated with each blade, each damper being hinged both to the hub and to the corresponding sleeve, the rotor including a system for controlling blade pitch via a respective pitch lever ( 16 ) secured to each sleeve, the rotor including two abutments designed to co-operate with tooling for blocking blade pitch, a first abutment presenting a bearing surface ( 35 , 36 ) matching a shape of revolution about an axis ( 18 ) of revolution to center a bearing face ( 41 , 53 ) of the tooling relative to said axis, and a second abutment ( 33 , 39 , 70 ) designed to position a bearing face ( 46 , 57 , 63 ) of the tooling axially along said axis of revolution, the first abutment and the second abutment being secured to a connection system hinged between a lag damper and the hub.
