Oilless Flange Bronze Bushing | Graphite Plugged Brass Flange Bearing, High Load Self Lubricating Bushing for Engineering Machinery

Overview

Our flanged graphite plugged bronze bushing (flange copper bearing) is a high-performance oilless self-lubricating bearing. It adopts high-strength bronze alloy as the base material, with solid graphite embedded inside as the solid lubricant. No oil refueling is required during operation. The integrated flange design simplifies installation and provides axial positioning, effectively resisting heavy load, impact and wear. Widely used in CNC machinery, injection molds, hydraulic cylinders, automation equipment and construction machinery articulated joints.

Features

1. Self-lubricating & Maintenance-free: Embedded graphite solid lubricant, suitable for intermittent motion, low speed, heavy load occasions where oil filling is difficult.
2. High Load & Wear Resistance: High strength bronze substrate, excellent compressive strength and anti-wear performance, long service life.
3. Integrated Flange Structure: Built-in flange with mounting holes for easy installation and axial limiting.
4. Wide Temperature Adaptation: Works stably under high temperature and low temperature working conditions.
5. Low Friction Coefficient: Reduce friction heat, avoid shaft seizure, good shock resistance.
