71163 is a special flat washer for transmission, clutch and hydraulic mechanisms of construction machinery. It is mainly used for end clearance compensation, pressure distribution and wear protection of shafts, bolts, pistons and other components. Made of high-quality steel with precision stamping, it has uniform thickness and flat end surface, which can effectively increase the force area and prevent indentation, deformation or wear of component ends under vibration and axial load.
Technical Parameters
- Model: 71163
- Type: Flat washer / Adjusting washer
- Material: High-quality carbon structural steel
- Surface Treatment: Blackening anti-rust treatment
- Precision: Stable thickness, high flatness of end face
- Operating Temperature: -40℃~120℃
- Structure: Thin circular ring with high concentricity and no burrs
- Features: Compression resistant, wear-resistant, stable clearance compensation
Application Scenarios
Suitable for transmission gears, bearing ends, pistons, spring seats, control valves and various shaft ends of construction machinery such as loaders, graders, rollers and forklifts. Used for axial clearance adjustment, end buffering, uniform pressure distribution and wear isolation, adapting to heavy-duty, vibration and frequent reversing conditions.
Common Faults & Troubleshooting
- Deformation and collapse: Caused by excessive axial load or material fatigue. Replace 71163 washer.
- Thinning due to wear: Abnormal clearance caused by long-term end friction. Replace with new washer.
- Dislocation and falling off: Due to eccentric installation or worn hole diameter. Reposition and replace washer.
- Rust and seizure: Caused by oil contamination or humid environment. Clean and replace with new part.
