72311 is a special locking and positioning component for transmission, clutch and hydraulic control mechanisms of construction machinery. It is usually used with springs, pins, pistons and other parts to realize automatic locking, limiting and anti-falling functions through its own elasticity. With compact structure and reliable locking, it can effectively prevent parts from loosening under vibration and frequent reversing conditions, ensuring safe operation of the transmission system.
Technical Parameters
- Model: 72311
- Type: Spring lock / Elastic locking pin
- Material: Spring steel or alloy structural steel
- Surface Treatment: Blackening / quenching anti-rust treatment
- Elastic Characteristic: Stable resilience with uniform locking force
- Operating Temperature: -40℃~120℃
- Structure: Elastic opening structure, easy installation and strong self-locking
- Features: Vibration resistance, anti-loosening, impact resistance, not easy to fatigue
Application Scenarios
Suitable for transmission shift mechanisms, clutch pistons, control valve assemblies, pin positioning, end cover limiting and other parts of construction machinery such as loaders, graders, rollers and forklifts. Used for elastic locking and anti-falling of small shafts, pins and plugs, adapting to frequent vibration, reversing and high-speed operation conditions.
Common Faults & Troubleshooting
- Loosening failure: Caused by elastic fatigue or opening deformation. Replace 72311 spring lock.
- Seizure and no rebound: Due to impurities or rust. Clean and replace with new part.
- Breakage damage: Resulted from impact overload or improper installation. Replace spring lock and check assembly space.
- Weak locking: Caused by elastic attenuation after long-term use. Replace directly to restore locking effect.
