What Is a Flange Linear Bushing?

Flange linear bushings (or linear bearings) are key components that enable precise linear motion by minimizing friction and wear. Designed for high-speed and heavy-load conditions, they ensure smooth, stable operation with minimal maintenance.

These bushings are widely used in:

  • Manufacturing and automation equipment

  • CNC machines and robotics

  • Packaging and assembly systems

Enhance motion accuracy and system longevity with our advanced flange linear bushing solutions.

Why Choose a Flanged Design?

Flanged linear bushings provide extra stability and support through their extended outer rings, offering:

  • Precise axial motion control

  • Improved load distribution

  • Reduced lateral displacement

This makes flanged bushings ideal for applications where shaft alignment, vibration resistance, and accurate positioning are essential.

Flanged Graphite Bronze Linear Bushings (LMF, LMK, LMH Series)

Flanged graphite bronze linear bushings are precision-engineered components designed for smooth, low-friction linear motion with zero external lubrication.
Made from high-strength bronze and embedded with solid graphite plugs, these bushings offer excellent wear resistance, high load capacity, and maintenance-free performance.

Available in LMF (round flange), LMK (square flange), and LMH (oval flange) types, they are ideal for automation, CNC machinery, and clean industrial environments that require oil-free operation and long service life.

Choose from LMF, LMK, or LMH flanged graphite bronze linear bushings — all offering oil-free, durable, and precise motion control.
Perfect for automation, CNC, and clean industrial applications requiring reliable, self-lubricating performance.

Structure & Features:
The LMF flange bushing has a circular flange for balanced, symmetrical mounting.
Made of bronze with graphite plugs, it provides continuous self-lubrication, ensuring smooth and quiet motion even under heavy loads.

Advantages:

  • Even 360° load support

  • Self-lubricating bronze–graphite surface

  • Oil-free, clean operation

  • Long service life with reduced maintenance

Applications:
Used in general industrial machinery, automation equipment, and linear motion systems requiring stable and balanced installation.

Structure & Features:
The LMK graphite bronze bushing includes a square flange for compact mounting and strong anti-rotation stability.
Its bronze body and graphite inserts maintain consistent lubrication under continuous or oscillating motion.
