Description: Journal bearings are constructed of carbon steel as the base, sintered porous bronze as the intermediate layer, laminated with PTFE and lead compound as the inner surface, and copper plated on the outer surface. The wrapped bushing is self-lubricating. It offers good friction properties, wear resistance and low noise level. Solid friction oilless bushing can work over a wide temperature range. Suitable for applications with sliding movements. Oil-free sleeve bearings are best suited for locations where self-lubricating properties of the material are required. Note: Split Line cannot be used for bearings. Specification: Material: Carbon steel base with sintered porous bronze Finish: PTFE and lead lamination, copper coating Friction factor (dry friction): 0.04-0.2 Friction factor (oil lubrication): 0. 02-0.07 Inner diameter: 6mm Outer diameter: 8mm Length: 10mm Item number: 6-pack
