PTFE Lined DU Bushing for Reciprocating Shock Absorber Rods

Engineered for reciprocating shock absorber rods and demanding industrial motion systems, the XIAYI PTFE Lined DU Bushing is a sleeve-type, self-lubricating bearing that pairs a precision bronze-steel backing with a low-friction PTFE/POM composite sliding layer. The result is smooth, quiet, maintenance-free operation that eliminates the need for external oil lubrication while delivering high load capacity and extended service life. The smooth machined finish and consistent dimensional tolerances make installation quick and straightforward.

Traditional oil-lubricated bushings create a range of operational and cost issues. The XIAYI DU bushing is designed to remove these concerns at the source:

• Constant re-lubrication: Conventional bushings demand regular greasing, adding labor hours and machine downtime.
• Oil leakage and contamination: Lubricant seepage can soil finished components and create unsafe, slippery work areas.
• Premature wear and scoring: Rough finishes and weak backing materials accelerate failure and force frequent replacements.
• High friction and heat build-up: Without a low-friction sliding layer, bearings run hot and reduce overall efficiency.
• Short service life: Inferior bushings cause unplanned stoppages and drive up the total cost of ownership.

By switching to a self-lubricating DU bushing, you gain a cleaner, quieter, and more dependable bearing that keeps production running.

• Self-lubricating PTFE lining — maintenance-free operation with no external grease or oil required.
• Bronze-steel backing — high static load capacity up to 250 N/mm² for heavy-duty applications.
• Low-friction composite layer — smooth, quiet running with minimal heat generation.
• Sleeve type with smooth finish — fast, precise installation and consistent dimensional accuracy.
• Cylinder and thrust pad configurations — flexible options for pumps, shock absorbers, and industrial equipment.
• IATF16949:2016 certified — automotive-grade quality, manufactured in Ningbo, China.

Hydraulic gear pumps — the self-lubricating sliding layer withstands high pressure and temperature, allowing reliable bearing performance without added lubrication.

Shock absorber rods and reciprocating systems — the cylindrical sleeve shape absorbs shock and vibration, reducing wear and extending component life.

Industrial equipment — from linear guides to pivoting joints, the DU bushing provides a dependable, low-maintenance bearing solution for a wide range of machinery.

XIAYI provides full customization of the DU bushing to match your exact specifications. We can tailor inner/outer diameters, length, wall thickness, and shape (cylinder or thrust pad) to your drawings, and we offer sample production for approval before mass production. With a supply capacity of 50,000 pieces per month and a minimum order quantity of 500 pieces, we are ready to support both pilot runs and high-volume programs.

Our engineering team supports you across the full product lifecycle, including installation guidance, application selection, troubleshooting, and ongoing technical consultation. Online resources such as product manuals, dimensional drawings, and instructional materials are available to help you get the most from your DU bushing.
