SINTERED IRON BUSHING 70X85X60

Impregnated Graphite Bushing – Sintered Iron Bushing 70×85×60

DALON’s 70×85×60 impregnated graphite bushing is a heavy-duty sintered iron bearing engineered for high-load, low-maintenance industrial applications. Manufactured through advanced powder metallurgy and embedded with solid graphite, this bushing provides consistent, self-lubricating performance even in demanding environments where traditional lubrication methods are unsuitable.

With a robust wall thickness and large internal diameter, the bushing supports substantial radial and axial loads, making it ideal for use in large electric motors, presses, construction machinery, hydraulic equipment, and conveying systems.

FAQ – Frequently Asked Questions

Q1: What are impregnated graphite bushings used for?
They are used to provide maintenance-free rotation support in high-load, high-wear environments without external lubrication.

Q2: Can this 70×85×60 bushing be used in continuous operation?
Yes. It's ideal for continuous or cyclic motion, offering long-term wear resistance and thermal stability.

Q3: What makes sintered iron better than bronze for large bushings?
Sintered iron has higher load-bearing capacity, superior wear strength, and is more cost-effective for larger dimensions.

Q4: How long is the production lead time for this bushing?
Custom-designed parts including tooling take 35–40 days. Production from existing molds typically delivers in 30 days.

Q5: What are the customization options?
You can customize ID, OD, length, material grade, and graphite content. Color coding and identification markings are also available.

Q6: What is the minimum order quantity for custom bushings?
MOQ depends on size and complexity. Contact DALON to discuss your specific requirements.

Q7: Can graphite bushings withstand high temperatures?
Yes, graphite allows for dry operation at elevated temperatures, but the full working range depends on the iron matrix specification.

Q8: What industries commonly use large graphite-impregnated bushings?
Industries include heavy machinery, steel processing, energy generation, mining, agriculture, and transportation equipment.
