Anping County Boli Hardware Wiremesh Products Factory, with over 25 years of manufacturing excellence since 1998, proudly presents our Corrosion-Resistant Powder Metal Oil-Impregnated Bearing Bushing, Zinc-Plated, Standard Compliant. This advanced bushing is engineered to deliver superior self-lubricating performance, exceptional durability, and reliable corrosion resistance, making it an ideal choice for demanding industrial applications. As a trusted manufacturer with an annual export value of US$5–10 million, we ensure every bushing meets rigorous quality standards, providing long-lasting operation and reduced maintenance costs for your equipment.
Our powder metal oil-impregnated bearing bushings are manufactured using state-of-the-art powder metallurgy technology, which allows precise control over porosity and oil retention. The zinc-plated surface adds an extra layer of protection against rust and environmental degradation, making these bushings suitable for use in humid or corrosive conditions. Our products are compliant with internationally recognized standards (specific certifications available upon request), ensuring consistent performance and interchangeability.
Key Features & Technical Specifications
- Self-Lubricating Design: Oil-impregnated pores continuously release lubricant during operation, reducing friction and wear without external oil supply.
- Zinc-Plated Finish: Provides excellent corrosion resistance, ideal for outdoor, marine, or chemical exposure environments.
- Powder Metallurgy Process: Enables complex shapes, tight tolerances, and uniform material density for consistent performance.
- Standard Compliant: Manufactured in accordance with industry standards (e.g., ISO, ASTM) – specific compliance details available on request.
- Wide Operating Temperature Range: Suitable for continuous use from -40°C to +120°C, with peak capability up to +150°C.
- Low Maintenance: Eliminates the need for frequent greasing or oiling, reducing downtime and labor costs.
- Customizable Dimensions: Available in various inner diameters, outer diameters, lengths, and flange configurations to fit your specific application.
- Eco-Friendly Operation: Powder metal production generates minimal waste, and the oil-impregnated design reduces lubricant consumption.

Frequently Asked Questions (FAQ)
Q1: What is the difference between an oil-impregnated bushing and a standard bronze bushing?
A: Oil-impregnated bushings are made from porous powder metal that is saturated with lubricating oil. During operation, oil is released from the pores to reduce friction, providing self-lubrication without external oil supply. Standard bronze bushings typically require periodic greasing or oiling, which can be less convenient in hard-to-reach locations.
Q2: How does the zinc plating improve corrosion resistance?
A: Zinc plating acts as a sacrificial barrier: it corrodes preferentially to protect the underlying steel or iron substrate. This makes the bushing suitable for use in humid, marine, or chemical-laden environments, significantly extending its service life compared to unplated alternatives.
Q3: Are these bushings compliant with any specific standards?
A: Our bushings are manufactured to meet common industry standards such as ISO, ASTM, and DIN. If you require specific certification or compliance documentation, please contact us with your requirements, and we will provide the relevant details.
Q4: Can the oil content be adjusted for different operating conditions?
A: Yes, the oil content (typically 15–25% by volume) can be customized based on your application's load, speed, and temperature. We can also select different oil viscosities (e.g., ISO VG 32, 46, 68) to optimize performance.
Q5: What is the typical lead time for custom orders?
A: For standard sizes, we can ship within 15–20 days after order confirmation. Custom orders typically require 25–35 days, depending on complexity and quantity. We offer expedited production for urgent requests.
Q6: How should I store these bushings before installation?
A: Store in a cool, dry place away from direct sunlight and extreme temperatures. Keep the original packaging until ready to use to prevent contamination or damage to the oil-impregnated pores. Avoid contact with solvents that could remove the lubricating oil.
Q7: Do you offer samples before bulk order?
A: Yes, we offer samples for evaluation. Sample costs and shipping are negotiable. Please contact our sales team with your requirements, and we will provide a sample of the standard size or a custom-made sample.
Q8: What is the minimum order quantity (MOQ)?
A: The MOQ for standard sizes is typically 500 pieces per size. For custom designs, MOQ may vary based on tooling and production setup. We are flexible and happy to discuss your needs.
