Polymer Bushong, High-Quality Gear Pump Bearing, PTFE/Bronze-Steel Composite SF-1

Description

Our Polymer Bushings and Gear Pump Bearings, crafted from advanced PTFE/Bronze-Steel Composite SF-1, redefine reliability in industrial systems. Engineered for gear pumps, hydraulic assemblies, and high-speed machinery, these bearings combine self-lubricating PTFE layers with durable bronze-steel substrates to deliver exceptional wear resistance, low friction, and extended service life. Ideal for applications where traditional lubrication is impractical, they ensure smooth operation in extreme temperatures, corrosive environments, and heavy-load scenarios.

Key Features & Benefits

1.Advanced Composite Material

• PTFE/Bronze-Steel SF-1: A tri-layer structure with PTFE (self-lubricating surface), sintered bronze (oil reservoir), and steel backing (structural integrity).
• Reduces friction by 40% compared to conventional bronze bearings.

2.Self-Lubricating Performance

• PTFE surface eliminates the need for external grease or oil.
• Maintains low friction coefficients (<0.1) even under dry or marginal lubrication.

3.Extreme Temperature Resistance

• Operates in temperatures from -200°C to 260°C (-328°F to 500°F).
• Resists thermal deformation and cold-flow issues.

4.High Load & Wear Resistance

• Withstands radial loads up to 50 MPa and axial loads in compact designs.
• Bronze layer distributes lubrication evenly, minimizing wear.

5.Corrosion & Chemical Resistance

• PTFE surface is inert to acids, solvents, and corrosive fluids.
• Ideal for food processing, chemical plants, and marine environments.

Applications

• Gear Pumps & Hydraulic Systems: Seamless integration in high-speed, low-lubrication pumps.
• Automotive: Transmissions, steering systems, engine components.
• Industrial Machinery: Compressors, turbines, material handling equipment.
• Food & Beverage: FDA-compliant bearings for clean environments.
• Marine & Offshore: Propulsion systems, winches, and deck machinery.
