Abstract: A pulley hub load cell assembled inside a hub opening of a pulley between a rolling element part and a pulley axle. The load cell has a body adapted to be placed inside the rolling element part and having an interior bore for insertion through the pulley axle. The body has at least one exterior location to be brought into contact with the rolling element part, and at least one interior location to be brought into contact with the pulley axle. The at least one exterior location and the at least one interior location of the body are spaced apart and offset such that a portion of the body there-between forms a cantilever configuration which is deformable when counter-loads are applied to the at least one exterior location and the at least one interior location of the body from the rolling element part and the pulley axle respectively.
