Performance Characteristics
1.High Wear Resistance: The internal structure typically contains multiple layers of reinforcing fibers or a special rubber formula to resist high-frequency vibrations.
2.Oil and Corrosion Resistance: The outer rubber layer provides some resistance to grease and corrosion from harsh road conditions.
3.Compression Resistance: Manufactured using a high-pressure vulcanization process, ensuring no deformation under loads of tens of tons.
Usage and Installation Precautions
1.Pressure Press-Installation Method: A press machine must be used to press the rubber in smoothly. Do not strike it directly with a sledgehammer, as this will cause the rubber to detach from the metal frame.
2.Lubrication Precautions: During installation, it is recommended to apply a small amount of neutral detergent or a special rubber lubricant. Do not use engine oil or grease, as mineral oil will accelerate rubber aging and corrosion.
3.Pair Replacement: The wear on both sides of the same balance shaft is usually similar. It is recommended to replace them in pairs to maintain suspension balance.
4.Inspection Cycle: For heavy-duty vehicles, it is recommended to inspect every 20,000-30,000 kilometers. If rubber cracking or eccentric vibration of the balance shaft is found, it must be replaced immediately.
