240/950 CAK30/W33- Spherical roller bearings-FGFA bearings

240/950 CAK30/W33 Spherical roller bearing with tapered bore and relubrication features

Self-aligning roller bearings are heavy-duty transmission components featuring automatic self-alignment. Their core comprises an inner ring, outer ring, barrel-shaped rollers, and a cage. They offer high load-carrying capacity, capable of simultaneously withstanding substantial radial loads and minor axial loads. These bearings exhibit excellent impact resistance, stable operation, and suitability for medium-to-low speed, heavy-load applications. They demonstrate low wear and extended service life.
