Maintenance-free metallic and multi-layered sleeve bearings increase slide performance, and minimize friction and vibration in heavy-load and high-temperature environments. Also known as composite bushings, they replace conventional bearings in dry and semi-lubricated applications. They have an embedded solid lubricant that's self-applying and never requires maintenance. They support radial or light axial load movements, especially where lubricants can't be used or may deplete quickly.
