摘要:
The bearing component(1) comprises a contact surface (2) inside a periphery (3), which surrounds a centre (4), and a coupling feature arranged inside the periphery for rotatably engaging a component of a piston rod perpendicular to the contact surface. The coupling feature includes at least one flexible feature (8) extending from the periphery towards the centre, and the flexible feature is arranged to be deflected towards the periphery by a force exerted on the flexible feature in a direction towards the contact surface and deflected towards the centre by a force exerted on the flexible feature in the opposite direction. The flexible feature may have a sloping surface (9) facilitating assembly and preventing disassembly in combination with a further component of the piston rod. The component of the piston rod may be a lead screw, and the piston rod may be used in a drug delivery device.
