The area to be lubricated in a chain set is the space inside the rollers as that is the place where all the friction happens. While the chain is in contact with the sprocket, the rollers rotate on the link. read more
Hence, the chain needs to be dipped in the lubricant after cleaning so that the oil can seep inside the space in the rollers. As far as lubricating the sprocket is concerned, grease should NOT be applied on it otherwise the chain, if slightly loose, will start slipping on the sprocket. read more
The current chain lubrication practice consists of applying a heavy oil or grease to the outside of the chain. While this does a nice job of lubricating the sprockets and the outside of the chain, it does little to protect the most vulnerable area of the chain: the contacting surfaces inside the pin and bushing/ plate/ roller/ hook. read more
Lubricating oil and grease are very different in their application. Their main application is to reduce friction but they act in different way. Lubrication oil is always preferred over grease because:-They help in cooling as well as lubrication. Grease cant be use in high speed applications. read more
