Series tapered roller bearings with flanged outer rings are highly efficient rolling bearings designed to withstand axial and radial loads. Its outer ring is equipped with a flange, which can be effectively fixed and positioned, enhancing the stability of the bearing in high loads and harsh working environments. The tapered roller structure enables it to withstand large radial loads as well as axial loads. It is suitable for heavy machinery, automobiles, aviation and other fields. The contact angle design of this bearing increases load capacity and service life while reducing friction and heat generation. With proper lubrication and maintenance, tapered roller bearings with flange on the outer ring can provide smooth operating performance and reliable work efficiency, and are an indispensable key component in modern mechanical equipment.
