Applications and Fit

Suitable Parts: 307E2/308E2 This product is designed for low-load rotating components such as the cab door lock mechanism and control lever shaft of excavators and 242D/246D skid steer loaders. It withstands radial loads, is suitable for high-frequency vibration conditions, ensures smooth operation, and prevents jamming and wear.

Application Scenarios: Suitable for long-term high-frequency vibration operations such as excavation and loading, including continuous excavation and shoveling operations. It ensures smooth rotation of components such as the door lock mechanism and control lever shaft, avoiding jamming and wear, reducing the risk of failure, and improving operational safety and reliability.

Compatible Use: It is used with door lock mechanisms and control lever shafts. The bearing provides rotational support, and the shaft transmits the load, meeting the needs of long-term operation and 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, using a special tool to press it in evenly to avoid uneven force on the outer ring, which could lead to deformation. Ensure a good fit between the bearing and the shaft/housing, without gaps or jamming.

Maintenance: Check the bearings every 200 hours for abnormal noises, looseness, and wear. Replace immediately if any abnormalities are found to prevent component jamming or damage.

Replacement: Disassemble the old part and check the wear on the mounting shaft and bearing housing. Repair any wear exceeding 0.05mm. Before installing the new part, check its dimensions and the condition of the steel balls to ensure it matches the original factory specifications. After installation, test for smooth rotation and no abnormal noise.
