Establishes and supports eccentric motion through a replaceable low-friction sliding bearing.
Eccentric Bushing (Eccentric Bushing)— Gyratory Crusher Wear part, position 06.
| Installation Position | Inside the eccentric assembly, corresponding to location 06 in the FLS cutaway diagram marked on this site. |
| Main Function | Establishes and supports eccentric motion through a replaceable low-friction sliding bearing. |
| Replacement Frequency | Medium replacement frequency; replace for excessive clearance, scoring, melting damage, local hot spots or abnormal metal content in the oil. |
| Item | Details |
|---|---|
| Material Options | Leaded tin bronze of the C93200/C93800 type, aluminium bronze or an OEM-specified centrifugally cast copper bearing alloy |
| Typical Properties and Acceptance Criteria | Operates at low speed, high contact pressure and oscillating motion with continuous oil lubrication. For example, the main composition ranges for C93200 are Sn 6.3–7.5%, Pb 6–8%, Zn 2–4% and Cu 81–85%. Confirm the actual grade and impurity limits against OEM requirements and the material standard. Acceptance checks cover composition, casting soundness, segregation, hardness, coaxiality, cylindricity, oil grooves, surface finish, interference fit and running clearance. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes; contact fatigue, lubricant contamination, temperature rise, seizure and seal failure |
