3327743 shaft shoulder ring is a special axial positioning and locking component for transmission mechanisms of construction machinery. It is mainly installed at the shaft diameter step to limit and fix rotating parts such as bearings, gears and bushings axially, preventing axial movement during operation. Made of high-strength steel with precision machining, it features compact structure and reliable positioning, maintaining stable locking effect under vibration, impact and high-speed operation conditions.
Technical Parameters
- Model: 3327743
- Type: Shaft shoulder ring / Axial positioning ring
- Material: High-quality carbon structural steel or alloy structural steel
- Surface Treatment: Blackening or phosphating anti-rust treatment
- Precision: Accurate inner and outer diameter, flat end face
- Operating Temperature: -40℃~120℃

Application Scenarios
Suitable for gearboxes, clutches, planetary gear trains, drive shafts, gear shafts and various supporting shafts of construction machinery such as loaders, graders, rollers and forklifts. Used for axial positioning and limit of bearing inner rings, gears, bushings and other parts to avoid axial displacement during operation and ensure meshing accuracy of transmission system.
Common Faults & Troubleshooting
- Loosening and falling off: Caused by excessive assembly clearance or wear deformation. Replace 3327743 shaft shoulder ring and check journal size.
- Deformation and cracking: Resulted from impact overload or improper installation. Replace with new ring and standardize installation process.
- Positioning failure: Caused by wear and thinning of ring, unable to limit effectively. Replace timely to prevent part movement.
- Wear and scratch: Due to interference friction with rotating parts. Check assembly position and replace ring.
