Abstract: The invention relates to a device for fastening an axle with rolling bearings in a cylindrical tubing comprising two annular sleeves having inward extensions for locking up the outer races of the rolling bearings with fastening members for relatively fixing the sleeves in place and with an outward shoulder at the end remote from the fastening members. The invention provides a device of the kind set forth, in which the sleeves are made from elastic material and the sleeves each have an inner groove at the end having the shoulder for fitting the outer races of the bearings and at the other ends hook-like fastening members fitting around one another, while the outer sleeve has longitudinal slots at said end.
