製品説明
The J503303 needle roller bearing is used in excavator hydraulic pumps or transmission systems to withstand radial loads and maintain stable operation of the pump shaft or rotor. This bearing is precision-machined from high-strength bearing steel, and the needle roller surface is hardened, providing high wear resistance and high load-bearing capacity. It can operate stably for extended periods under high load, high vibration, and high temperature environments. Suitable for excavator pump system repair or replacement.
Features and Advantages
• High Load-Bearing Capacity: Can withstand high radial loads in excavator pump systems.
• Wear and Durability: The needle rollers and inner and outer rings undergo high-precision heat treatment, resulting in a long service life.
• Low Friction Operation: Ensures smooth pump shaft rotation, improving hydraulic efficiency.
• Compact Structure: Precise dimensions, easy installation, and can directly replace original parts.
• Long-Term Reliability: Adaptable to high temperature, high vibration, and high load operating environments.
