Bearings play a crucial role in supporting rotors, reducing friction, and transmitting power in fluid transmission equipment. Among them, fan bearings need to adapt to high-speed rotation and slight misalignment conditions, air compressor bearings need to withstand alternating loads and suppress vibration noise, and water pump bearings must balance sealing and corrosion resistance to cope with liquid media. These applications usually use self-aligning roller bearings, angular contact ball bearings, or ceramic bearings, and optimize lubrication and sealing design to ensure efficient stability and long service life of the equipment under continuous operation.

Bearings play a core supporting role in electric tools such as drills, chainsaws, water guns, weed removers, water pumps, cutting machines, and angle grinders. The spindle bearings of electric drills need to withstand high-speed rotation and axial impact loads, while the transmission bearings of chainsaws and cutting machines require high rigidity to cope with severe vibrations. The impeller bearings of water guns and water pumps need to have excellent waterproof and rust proof performance, while the bearings of weed removers and angle grinders need to maintain long-lasting lubrication in dusty environments. These tools usually use deep groove ball bearings, needle roller bearings, or sealed ceramic bearings, which ensure stable operation and tool life under high load conditions through optimized wear resistance and heat dissipation design.

Bearings play a critical supporting role in precision equipment such as printers, shredders, robots, and drones. The paper feed roller and print head guide rail bearings of printers need to ensure high-precision and low-noise operation, while the tool bearings of shredders need to withstand high-strength shear forces. Robot joint bearings require high rigidity and repetitive positioning accuracy to achieve flexible movement. The motor and rotor bearings of drones need to balance lightweight and high-speed stability. These applications usually use micro deep groove ball bearings, cross roller bearings, or ceramic hybrid bearings, which meet the strict requirements of low friction, long life, and high reliability of equipment through precision manufacturing and special lubrication.

Bearings are widely used in key components such as traction machines, guide rails, car door machines, and pulley systems in elevator systems. The main shaft bearing of the traction machine needs to withstand high torque and continuous operation loads, the guide rail bearing requires high precision to ensure smooth lifting and lowering of the car, the door machine bearing needs to achieve fast and silent opening and closing actions, and the pulley system bearing needs to reduce the friction loss of the steel wire rope. These applications usually use self-aligning roller bearings, deep groove ball bearings, or self-lubricating sliding bearings to ensure the safety, comfort, and long-term reliability of elevator operation through strengthened sealing and wear-resistant design.

Bearings play a core role in supporting rotors, reducing friction, and ensuring efficient energy conversion in industrial motors. Small motors typically use deep groove ball bearings to balance radial and axial loads, while medium to large motors use cylindrical roller bearings or angular contact bearings to cope with high loads and complex stress conditions. High speed motors may choose hybrid ceramic bearings to reduce friction losses and temperature rise. These bearings need to have high precision, long life, and excellent heat dissipation performance, and prevent lubricant leakage and pollutant invasion through sealing design, thereby ensuring the continuous and stable operation and energy efficiency performance of industrial motors in harsh environments.
