Why the 3363 0853 21 Insert is Critical
Hydraulic breakers operate under intense pressure and constant percussion. Standard threads in cast components can wear out or “strip” over time. The 3363 0853 21 Threaded Insert solves this by providing:
1. Superior Thread Strength
Made from hardened steel, these inserts are designed to handle the high torque requirements of breaker assembly bolts. They act as a heavy-duty anchor, preventing bolt loosening during operation.
2. Vibration Resistance
Epiroc breakers generate massive kinetic energy. This insert is engineered to distribute load forces evenly, reducing the risk of fatigue cracks in the breaker’s main frame or head.
3. Ease of Maintenance
Using a threaded insert allows for easier repairs. If a thread becomes damaged, the insert can often be replaced without needing to weld or replace the entire housing, saving you thousands in repair costs.
Compatible Models
While primarily associated with the HB (Heavy Breaker) series, this part is used across several Atlas Copco and Epiroc platforms. Always verify your parts manual for the specific application.
- Atlas Copco HB Series
- Epiroc HB Series (e.g., HB2000, HB3100, HB4700, HB5800)
- Specific MB/SB Series (Depending on the specific assembly)
Technical Features
- Precision Machined: Ensures a perfect fit with OEM bolts.
- Corrosion Resistant Coating: Prevents seizing and rust in harsh outdoor environments.
- OEM Quality: Manufactured to the exact tolerances required by Epiroc global standards.
Pro Tip: When installing the 3363 0853 21, ensure the receiving hole is clean and free of debris. Use the recommended thread-locking compound to ensure the insert stays seated permanently during high-impact work.
