Bearings are the core supporting components of industrial transmission systems, widely adapted to various transmission equipment to ensure efficient power transmission. In gear transmission systems, high-speed shafts of reducers and speed reducers are commonly equipped with angular contact ball bearings to withstand combined loads, while low-speed heavy-duty shafts are equipped with tapered roller bearings or self-aligning roller bearings to compensate for installation deviations and enhance impact resistance; In belt/chain transmission equipment, the roller shafts of conveyors and elevators often use deep groove ball bearings to achieve radial positioning, while the motor output shaft is adapted to high-speed operation through cylindrical roller bearings; In addition, in transmission connecting components such as couplings and clutches, needle roller bearings are often used to adapt to compact installation spaces, while in precision transmission scenarios (such as machine tool spindles), high-speed angular contact ball bearings need to be paired to ensure transmission accuracy and stability, fully supporting various power transmission needs in industrial production.
