What Is The Purpose Of A Bushing ?
Mar 02, 2026| Industrial Machinery Sector
• Bearing Replacement/Complement: In low-speed, heavy-load scenarios with less stringent precision requirements, such as connecting rods in mining machinery or shaft supports in crushers, powder metallurgy bushings can replace certain rolling bearings to reduce equipment costs while offering excellent self-lubricating properties and decreasing maintenance frequency.
• Vibration and noise reduction: In equipment with high-frequency impacts, such as presses and injection molding machines, the porous structure of the bushing absorbs vibrational energy, reduces collision noise between components, and enhances operational stability.
Automotive manufacturing field
• Chassis System: Powder metallurgy bushings can cushion vibrations transmitted from the road at components such as suspension control arms and steering tie rods, enhancing vehicle ride comfort while preventing abnormal noises caused by direct friction between metal parts.
• Powertrain System: The bushings at the camshaft and balance shaft of the engine provide stable support for the shaft components. Combined with their self-lubricating properties, they adapt to the high-temperature, high-speed working environment inside the engine, extending the service life of the parts.
In the field of home appliances and office equipment
• Household appliance components: Powder metallurgy bushings are used in the drum shaft of washing machines and the fan shaft of air conditioners, which meet the long-term stable operation needs of household appliances due to their low cost and low noise characteristics, without the need for additional complex lubrication structures.
• Office equipment: The high-precision and good wear resistance of the bushing at the paper feed roller shaft of the printer and the transmission shaft of the copier can ensure the accuracy of equipment transmission and reduce the occurrence of paper jams and other faults.
