Flanged Self-Lubricating Bushings

Self-Lubricating Flanged Bushings | Graphite Plugged Oil-Free Bearings

📌 Flanged Oil-free bushing Overview

Flanged Self-Lubricating Bronze Bushings (Round Flange Type)

High-performance flanged self-lubricating bushings, also known as graphite-plugged oilless bronze bearings. Made of high-strength brass/bronze alloy with embedded solid graphite lubricants, these bushings eliminate the need for external grease or oil. The integrated round flange ensures easy installation, precise axial positioning, and stable support for both radial and light thrust loads. Ideal for high-load, low-speed applications in automation, molds, and industrial machinery.

✨ Key Features

• Self-Lubricating, Maintenance-Free: Embedded graphite plugs provide continuous lubrication, no oil refilling required
• Low Friction & High Wear Resistance: Solid graphite combined with bronze alloy minimizes friction and extends service life
• Flanged Design: Round flange for quick mounting, prevents axial movement, and simplifies alignment
• High Load Capacity: Durable bronze base supports heavy radial loads in continuous operation
• Corrosion & Temperature Resistant: Suitable for harsh environments, operating from -40°C to 150°C
• Precision Machining: Tight tolerance control for smooth linear and oscillating motion

🏭 Applications

• Automation equipment & linear motion systems
• Injection molds, die-casting molds, and stamping dies
• Packaging machinery, conveyors, and material handling systems
• Food processing equipment (no oil contamination risk)
• Textile machinery, printing presses, and hydraulic tools
• General industrial machinery requiring maintenance-free operation

Installation Instructions for Flanged Self-Lubricating Bushings

Preparation

• Clean the housing bore and shaft thoroughly to remove burrs, dirt, and oil.
• Ensure the housing bore meets the recommended tolerance (H7 or H8) for a proper press fit.

Installation

• Use a press fit to install the bushing into the housing bore. Apply even pressure on the bushing’s outer surface, never on the inner bore or graphite plugs.
• Align the flange with the housing face during insertion to avoid tilting.
• For interference fit, cool the bushing or heat the housing slightly (≤120°C) for easier assembly if needed.

Alignment & Check

• After installation, verify the bushing is fully seated and flush with the housing.
• Insert the shaft by hand to confirm smooth movement without binding.

Operation

• Run the equipment under light load for 1–2 hours to bed in the graphite lubricant.
• No additional grease or oil is required.
