Product Advantages
**High temperature & ash wear resistance**：
  Special material formula adapted to incinerator flue gas, resist fly ash abrasive wear, avoid rapid failure under 
  dusty hot gas.
**Anti-corrosion for flue gas**：
  Resist weak acid / alkali corrosive components from waste combustion flue gas.
**Low friction & vibration reduction**：
  Stable sliding performance, reduce fan shaft friction, lower vibration & noise, protect fan shaft from scoring.
**Long service life & reduce downtime**：
  Long working life, reduce frequent replacement, save maintenance cost for waste incineration plant.
**Customizable dimension**：
OEM & ODM available, produce strictly according to original fan drawing or samples.
**Easy installation & replacement**：
Direct replacement for old bushing, simple on-site assembly.
**Strict quality control**：
Each piece checked for dimension, material hardness, surface inspection before shipment.

Working Principle
The flue gas fan bushing is a sliding bearing sleeve installed between fan rotating shaft and fan housing / bearing seat. It forms a sliding friction pair with the rotating shaft.
Under high-temperature flue gas operation, the bushing bears radial load of fan rotor. Self-lubricating material releases solid lubricant during operation to form a continuous lubrication film between shaft and bushing inner surface. The lubricating film isolates metal direct contact, reduces friction, absorbs partial vibration, protects fan shaft and bearing housing from abrasion and seizure, and keeps the incinerator flue gas fan running smoothly in continuous operation.

Application Scenarios

• Municipal solid waste incineration plant flue gas induced draft fan
• Hazardous waste incinerator flue gas fan
• Waste-to-energy power plant ID fan
• Medical waste incineration exhaust fan
• Industrial waste liquid incinerator flue gas blower
• Boiler & incineration flue gas treatment system fan spare parts
• Environmental protection flue gas dedusting, denitration supporting fan

Maintenance Instructions
1. Regular inspection: Check fan vibration, noise and bushing temperature every 1~3 months. Monitor temperature rise and abnormal noise.
2. Clear dust: Remove accumulated fly ash around bushing position regularly to avoid abrasive ash entering friction clearance.
3. Lubrication: For grease-type bushing, replenish high-temperature grease as maintenance schedule; Self-lubricating composite bushing does not need frequent refueling.
4. Wear measurement: Periodically measure clearance between shaft and bushing. Replace the bushing when clearance exceeds allowable limit.
5. Replacement: Stop & lock out fan before disassembly. Check fan shaft surface condition; if shaft is scratched, repair shaft before installing new bushing.
6. Storage: Keep spare bushing dry, avoid moisture, corrosion and deformation before installation.

FAQ

Q1: What material should I choose for incinerator flue gas fan bushing?

A: For high temp + fly ash flue gas, bimetal bronze bushing or graphite embedded bushing is recommended. If flue gas contains strong corrosive medium, PTFE composite high-temperature bushing will be better. Please provide working temperature, gas medium and fan speed for material recommendation.

Q2: Can you make bushing according to our drawing or old sample?

A: Yes, OEM custom service available. Send us 2D drawing or physical sample photo with dimension, we can quote and produce.

Q3: What is the lead time?

A: Standard size in stock: 1~3 days. Custom machining: 7~15 working days based on quantity.

Q4: What is the warranty of the bushing?

A: 12 months warranty under correct installation & normal working condition. Warranty excludes damage caused by misalignment, overload, improper installation, foreign ash blockage.

Q5: Is it suitable for waste to energy plant induced draft fan?

A: Yes, specially designed for waste incineration & waste-to-energy flue gas fan, fit continuous 24h running condition.
