Metal-polymer bushings are composite bearings that blend the durability of metal with the friction-reducing qualities of polymers. Below are the essential details about straight metal-polymer bushings:

Structure and Composition:

• Incorporate a metal backing (commonly steel or bronze) for robustness and structural support.
• Feature a sintered porous bronze layer filled with a polymer lining (usually PTFE or POM).
• The polymer lining acts as a low-friction surface for operation.

Key Features and Benefits:

• Self-lubricating, capable of functioning either dry or with added lubrication.
• Offer a low friction coefficient for smooth performance.
• Provide high resistance to wear, contributing to a prolonged lifespan.
• Compact, singular construction helps conserve space and reduce weight.
• Resilient under harsh conditions.
• Require little to no maintenance.
• Resistant to chemicals and corrosion.

Available Types:

• Straight cylindrical bushings (non-flanged).
• Come in various sizes, with inner diameters typically from 3mm to 400mm.
• Available in standard thicknesses of 0.75mm, 1mm, 1.5mm, 2mm, 2.5mm, and 3mm.

Applications:

• Ideal for continuous sliding, rotating, and oscillating motions.
• Commonly utilized in sectors like automotive, industrial machinery, and electrical appliances.
• Manufacturers may provide customization options such as groove patterns, lubricant indents, or tailored shapes to meet specific operational needs.

When choosing a metal-polymer bushing, it’s important to consider factors such as load capacity, operating speed, temperature range, and environmental conditions to ensure the bushing performs optimally in your specific application.
