PRODUCT

Description

The Inner Eccentric Bushing (Part No. 2207-0561) is the critical tribological interface in the drivetrain of the Symons 4 ¼ Ft Standard Cone Crusher. Unlike generic aftermarket options, our bushings are engineered using Centrifugal Casting technology to ensure a dense, porosity-free microstructure capable of sustaining the immense radial crushing loads.

This component serves a vital mechanical function: it acts as the sacrificial wear bearing between the rotating Eccentric Assembly and the stationary Main Shaft. As a premium crusher parts supplier, we utilize High-Lead Tin Bronze to guarantee “Anti-Seize” properties, protecting your main shaft from catastrophic scoring during lubrication failures.

Replacement Interval

  • Typical service life: 18-36 months under standard operating conditions.
  • Replacement is condition-based; recommended inspection during major overhauls.
  • Monitor hydraulic system pressure and crusher vibration levels as indicators of wear.

Failure Types Caused by Worn Inner Bushings

  • Hydraulic system inefficiency and inability to maintain correct crusher setting.
  • Increased vibration and abnormal noise from the eccentric assembly.
  • Reduced crushing performance and inconsistent product gradation.
  • Accelerated wear on the main shaft and eccentric sleeve.
  • Potential for galling and seizure, leading to catastrophic crusher failure.

Looking For Inner Bronze Bushings

As a professional crusher parts manufactore, we guarantee that these inner bushings are precision-machined to exact OEM tolerances. Each bushing undergoes dimensional verification and material certification to ensure it performs as a reliable component among parts for Symons crushers.

“Authoritative Engineering Data: All critical metallurgical specifications and dimensional tolerances (e.g., ±0.05mm) are strictly governed by the master English documentation. While localized versions are provided for operational reference, the English original remains the sole binding authority for quality inspection and technical compliance.”
