SF1 Composite Copper Sleeve Oil Selflubricating Bearing is a compact bushing designed for maintenance operation in equipment where an oil bearing is preferred. The bearing uses a composite copper sleeve that provides selflubricating performance, reducing the need for periodic lubrication and minimizing lubricant leakage in sensitive environments. Key benefits Oil selflubricating design reduces maintenance and downtime Composite copper sleeve delivers low friction and wear resistance Suitable for compact, spacelimited assemblies Helps protect shafts from wear while simplifying installation and servicing Durable construction with a standard size set for easy replacement Key attributes Model: SF1 Material: Composite copper sleeve Function: Oil selflubricating bearing Inner diameters (bore sizes): 38 mm, 40 mm, 45 mm, 50 mm, 55 mm Overall dimensions: 55 x 60 x 30 mm Package quantity: 1 piece Compatibility and installation notes Designed to fit shafts with matching bore sizes listed above Select the bore size to match the shaft diameter for proper clearance and performance Verify the outer dimensions and mounting fitment to ensure compatibility with the housing Use cases and applications Small machinery and automation components that require lowmaintenance bushings with oil operation Conveyor rollers and fans where lubricant leakage must be avoided or kept to a minimum Hobby robotics and DIY projects needing compact, selflubricating bushings with interchangeable bore options This SF1 bearing combines a composite copper sleeve with an oil, selflubricating design to deliver reliable, maintenancelight performance across a range of smallscale applications. The available inner bore options enable precise matching to the shaft diameter, supporting straightforward replacement and installation.
