Product Overview

Our self-lubricating bushing assemblies are precision-engineered, maintenance-free components that deliver smooth, reliable linear motion in demanding industrial environments. These CNC machined oilless bushings feature square or round flange designs and completely eliminate the need for external lubrication. With exceptional wear resistance, ultra-low friction, and extended service life, they serve as an ideal, cost-effective replacement for traditional oil-lubricated linear bearings.

Perfect for automation equipment, CNC machinery, packaging systems, medical devices, and more, these bushings help reduce maintenance costs while maximizing uptime.

Key Features

✅ Self-Lubricating Technology The high-performance bronze liner is impregnated with solid lubricants (graphite or PTFE). As the shaft moves, it automatically releases a thin lubricating film, ensuring consistent low-friction performance without any added oil or grease.

✅ Square & Round Flange Configurations Choose from square flange for superior stability in high-torque applications or round flange for compact, space-saving installation. Both designs include pre-drilled mounting holes for fast and secure assembly.

✅ Precision CNC Machined Housing The outer housing is expertly CNC machined from high-grade stainless steel or carbon steel, guaranteeing tight tolerances, excellent surface finish, and precise alignment for optimal fit and performance.

✅ True Maintenance-Free Operation No periodic lubrication required. These oilless bushings are perfect for hard-to-reach areas, high-temperature environments, or applications where oil contamination must be avoided.

✅ High Load Capacity & Durability Engineered to handle heavy radial loads, intermittent motion, and high-speed operation with minimal wear, ensuring long-term reliability even in tough conditions.

✅ Corrosion-Resistant Options Stainless steel housing versions provide excellent resistance to moisture, chemicals, and harsh environments — ideal for food processing, marine, and washdown applications.

Common Applications

• Industrial Automation & Robotics — Linear guides, robotic arms, and pick-and-place systems requiring maintenance-free, precise motion.
• CNC Machine Tools — Spindles, tool changers, and linear axes where precision and resistance to debris are essential.
• Packaging & Printing Machinery — High-speed lines that demand clean, oil-free operation to protect products.
• Medical & Laboratory Equipment — Diagnostic machines, lab automation, and surgical tools needing clean, reliable performance.
• Food & Beverage Processing — Stainless steel variants excel in washdown environments and prevent lubricant contamination.
• Textile & Agricultural Machinery — Built to withstand dust, debris, and continuous operation with minimal downtime.

Quick Installation Instructions: Flanged Self-Lubricating Oilless Bushing

• Preparation: Clean the shaft and mounting surface; verify all dimensions match your specifications.
• Align: Place the square/round flange bushing on the mounting plate and align the holes.
• Secure: Tighten bolts evenly in a crisscross pattern; do not over-tighten.
• Insert Shaft: Slide the shaft straight into the bushing slowly. Do not force or hammer.
• Check: Test the shaft movement to ensure it runs smoothly with no binding.
• Maintenance: These are maintenance-free bushings. Do not add oil or grease. Keep free of dust/debris.
