The device includes a tube (1) within the axle, which has apertures (6) along its circumference. The tube has discs (2,3) engaged at each end, one of them having a threaded central aperture (4) to receive the oil injector's head (5). The oil fills the tube's cavity then goes through the apertures and fills the interstice between tube and rollers.
