When bulldozers are operating (such as pushing hard soil or climbing slopes), the bearings need to withstand huge impact loads (such as the instantaneous load of the driving wheel bearings reaching more than 10 tons), so it is necessary to choose bearings with high bearing coefficients (such as tapered roller bearings and self-aligning roller bearings), and improve their impact resistance by thickening the ring and Roller nneɛma no a wɔbɛhyɛ mu den.
