Abstract
A self-lubricating assembly for a linear guideway comprises two oil containers and at least a connector. Each of the oil containers has a body, at least one absorber, and a flexible lubricating element. A holding groove for accommodating the lubricant is formed inside the body, the outside of the body is formed with a rail contacting portion and a connecting portion. The absorber is disposed in the holding groove for sucking the lubricant. The flexible lubricating element is disposed firmly in the rail contacting portion, and at least a part of the flexible lubricating element is extended to the holding groove for sucking the lubricant. The diffusion velocity of the lubricant in the absorber is faster than the diffusion velocity of the lubricant in the flexible lubricating element. At least a connector connects the connecting portions of the oil containers, so the lubricant flows between the two oil containers.
