Compatibility and Applications

Compatible Parts: Rotating components such as joysticks, sensor arms, and linkages in the cabs of 307E2/308E2 excavators and 242D/246D skid steer loaders. Bears radial loads, suitable for high-frequency vibration conditions, ensuring smooth operation and preventing jamming and wear.

Application Scenarios: Suitable for long-term high-frequency vibration operations such as excavation and loading, including continuous excavation and shoveling operations. Ensures smooth rotation of joysticks, sensor arms, and other components, avoiding jamming and wear, reducing the risk of failure, and improving operational safety and reliability.

Compatible Usage: Compatible with joysticks, sensor arms, and mounting shafts. Bearings provide rotary support, and the shaft transmits loads, suitable for long-term operation, preventing component fatigue and loosening.

Installation and Maintenance Points

Installation: Clean the mounting shaft and bearing housing, confirming that the bearing size matches the shaft and housing; use the press-fit method for installation, employing a special tool to press evenly, avoiding uneven force on the outer ring that could cause deformation, ensuring a good fit between the bearing and the shaft/housing without gaps or jamming.

Maintenance: Check the bearing for abnormal noise, looseness, and wear every 200 hours. If any abnormalities are found, replace it immediately to prevent component jamming or damage.

Replacement: Disassemble the old part and inspect the mounting shaft and bearing housing for wear. Wear exceeding 0.05mm requires repair; before installing the new part, check the dimensions and needle roller condition to ensure consistency with original factory specifications. After installation, test for smooth rotation without abnormal noise.
