SF1 Composite Copper Sleeve Oil Selflubricating Bearing is a maintenance friendly bearing designed for rotating shafts in compact applications. The copperbased composite sleeve provides selflubricating properties, reducing or eliminating the need for external lubrication and helping keep equipment clean and reliable. Key benefits Oil selflubricating operation to reduce maintenance and prevent lubricant leaks Copperbased composite sleeve offers wear resistance for longer service life in dry or lowlubrication environments Simple replacement for compatible shaft sizes with predefined inner diameters Compact bushing design that supports reliable operation in small to midsize machinery Corrosion resistant construction suitable for varied industrial settings Key attributes Functionality: oil, selflubricating bearing sleeve Compatibility: designed for shafts with inner diameters of 38, 40, 45, 50, and 55 mm Size: bushing package size 40x44x70 mm; 1 piece Material: composite copper sleeve Performance: suitable for continuous operation in dry or minimally lubricated conditions Specifications and compatibility Brand/model: SF1 Inner diameter options: 38 mm, 40 mm, 45 mm, 50 mm, 55 mm Bushing size: 40x44x70 mm (1 piece) Material: composite copper sleeve Lubrication: oil, selflubricating Use cases Conveyor rollers and material handling equipment where lubrication is restricted and clean operation is important Automation components such as robotic joints or linear actuators that require reliable, maintenancelight bearings Small motors, gearboxes, or drive shafts in equipment where regular lubrication is difficult or undesirable How to select Choose the inner diameter to match your shaft: 38, 40,
