Standard Copper Alloy Oil-Free Bronze Bushings are mechanical components that are designed to operate without the need for external lubrication. These bushings are typically made from a copper alloy, which offers excellent wear resistance, durability, and low friction properties.
The oil-free design of these bushings eliminates the need for regular lubrication and maintenance, making them ideal for applications where lubrication is not possible or desirable. The copper alloy material provides strength and corrosion resistance, ensuring reliable performance in various environments.
Standard Copper Alloy Oil-Free Bronze Bushings are commonly used in a wide range of industries, including machinery, automotive, aerospace, and marine. They are suitable for applications involving rotating shafts, pivot points, and other moving parts that require low-friction and wear-resistant bushings.
When selecting Standard Copper Alloy Oil-Free Bronze Bushings, it is important to consider the specific requirements of your application, including the dimensions, load capacity, and operating conditions. It is also recommended to consult with a manufacturer or supplier to ensure that the bushings you select meet your needs and will perform optimally within your system.

Reasons for Selecting Graphite Impregnated Brass Bearings
1. Total Self-Lubricating: No oil or grease required
The self-lubricating features allow bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.
2. Excellent Wear Resistance:
Excellent wear resistance is achieved under severe working conditions, such as heavy load, low velocity, reciprocating, oscillating and intermittent motions where the formation of oil film is difficult.
3. Low Coefficient of Friction: 0.04 to 0.2 typical:
Self-lubrication with specially embedded solid lubricants reduces friction.
4. Wide Operating Temperature Ranges: -415° ° to 1,100° °F
Superior performance is exhibited under high and low temperature conditions.
5. Corrosion and Chemical Resistance:
Performance is not affected by water and caustic chemicals.
6. Designed to Exceed Your Requirements:
High precision products with close tolerances.
7. Cost Competitive:
Maintenance, replacement, and end-item downtime cost reduced due to the exceptional service life compared to similar self-lubricating products.
