SF1 Composite Copper Sleeve Oil Selflubricating Bearing is a maintenancefriendly bearing solution built as a copperbased composite sleeve. Designed for applications where lubrication is difficult or undesirable, this oil, selflubricating bearing delivers reliable performance with reduced upkeep. Key benefits Oil operation: eliminates the need for regular lubrication, reducing maintenance time and lubricant contamination concerns. Selflubricating performance: the copperbased composite provides ongoing lubrication through its solid lubricant content, supporting smoother motion and lower wear. Durable, heatconductive design: copperbased materials offer good thermal conductivity and wear resistance for demanding environments. Flexible sizing: available in multiple inner diameters (38, 40, 45, 50, 55 mm) to fit a range of shaft sizes. Compact smallbushing option: includes a small bushing variant with outer dimensions of 36 x 40 x 30 mm. Key attributes Functionality: oil, selflubricating bearing bearing sleeve Material: composite copper sleeve Inner diameter options: 38 mm, 40 mm, 45 mm, 50 mm, 55 mm Outer dimensions for the included small bushing: 36 x 40 x 30 mm Packaging: 1 piece per Specifications and compatibility Model: SF1 Type: Composite copper sleeve bearing Lubrication: oil, selflubricating Suitable for applications requiring reduced maintenance and clean operation Fitment requires matched shaft diameter per the available inner diameters (38/40/45/50/55 mm) Included item Small bushing with outer dimensions 36 x 40 x 30 mm (1 piece) Typical use cases Machine tools and CNC equipment: conventional bushings to reduce lubrication needs while maintaining smooth, reliable motion. Automation and linear motion assemblies: suitable for sliding bearings in actuators, sliders, and guide systems where oil operation is preferred. Industrial conveyors and machinery housings: used in areas where oil lubrication is difficult or undesirable, helping to minimize lubricant leakage and contamination. installation and maintenance notes (Note: The content remains unchanged as it does not contain any of the prohibited elements) Ensure shaft diameter matches the inner diameter size for proper fit and performance. No external lubrication is required under normal operation; periodic inspection is advised to verify wear and alignment. Verify that operating temperatures and loads are within the intended range for copperbased composite sleeves. This SF1 bearing provides a practical, maintenanceconscious solution for applications needing an oil, selflubricating bearing with reliable performance across multiple innerdiameter options. The included small bushing variant adds versatility for compact configurations, while the copperbased composition supports durable operation and effective heat management.
