DIY projects and custom builds. Automotive components and parts. Application Scenarios. Shore D Hardness: 74. Engineering Plastic Bushing JFM Self-lubricating Plain Sleeve Bearing ID 3-70 mm About this Product These premium flanged JFM maintenance-free engineering plastic bushings are manufactured from high-performance polymer material, offering exceptional wear resistance, low friction, and self-lubricating properties. The integrated flange design ensures easy alignment and mounting, making them ideal for light-to-medium load applications in industrial machinery, automotive parts, and DIY projects. Key Features Maintenance-Free Operation: Self-lubricating properties eliminate the need for external lubrication, reducing downtime and maintenance costs. Flange Design: Built-in flange ensures proper alignment, prevents axial movement, and simplifies installation. Electrical insulation: With excellent insulating properties, it is ideal for use in electrical equipment. Installation Notes：These are press-fit bearings, requiring housing bores with H7 tolerance for proper installation.Recommended shaft surface roughness: Ra 0.2–0.8 μm to prevent squeaking or accelerated wear.Chamfer the shaft ends at 20–30° for smooth installation.
