Compatibility and Application

Suitable Parts: Boom joints and connecting rod hinge points of the working device in 259D3/279D3 skid steer loaders and 906H/907H mini excavators. Bears radial and bidirectional axial loads, suitable for medium-speed and medium-load conditions, ensuring precise positioning and smooth operation of components, preventing vibration wear, and improving operational reliability.

Application Scenarios: Suitable for frequent load-changing operations such as excavation and loading, including continuous excavation and shoveling operations. Ensures smooth operation of the boom joints and connecting rod hinge points of the working device, preventing component loosening and wear, reducing the risk of failure, and improving operational safety and reliability.

Compatible Use: Used with 085-3552 bushings, 083-5018 axle retaining rings, and 083-5020 adjusting rings. The bearings provide radial and bidirectional axial loads, the bushings reduce friction and wear, the retaining rings provide axial positioning, and the adjusting rings control bearing clearance. Suitable for long-term high-frequency vibration operations, preventing component fatigue damage.

Installation and Maintenance Points

Installation: Clean the journal, bearing housing bore, and bearing; check dimensional tolerances. Use specialized tools for press-fitting; do not strike. After installation, ensure the bearing fits well with the journal and bearing housing bore, without jamming or looseness, and rotates freely without abnormal noise. Axial clearance should meet specifications (0.02-0.05mm).

Maintenance: Check bearing lubrication status and for any abnormal noises/vibrations every 200 hours. Regularly replenish lithium-based grease (NLGI 2 grade). Avoid contact with water and dust to prevent rust and wear.

Replacement: Use a specialized puller for disassembly to avoid damaging the journal/bearing housing bore. Before installing a new bearing, verify its dimensions and accuracy. After installation, test for smooth operation without abnormal noise.
