To prevent oil-free bearing rust, the surface must be pre-treated. the cleaning method should be selected according to the nature of the surface of the anti-corrosion material and the conditions at the time. solvent cleaning, chemical cleaning, and mechanical cleaning are commonly used. after cleaning, dry it with filtered dry compressed air, dry it in a dryer at 120~170°c, or dry it with clean gauze.
Self-lubricating oilless bearings feature self-lubricating functions and demonstrate high performance, which normal plain bearings cannot provide, for fl uid lubrication, boundary lubrication, and dry friction fields.
A sleeve is a thin tube or sleeve that allows relative motion by sliding (our type) versus rolling. The sleeve can also be called a plain bearing. However, the term bushing would be redundant. So a bushing is a bearing, but a bearing is not necessarily a bushing.
Self-lubrication is characterized by the bearing’s ability to transfer microscopic amounts of material to the mating surface. This transfer process creates a film that provides lubrication and reduces friction along the entire length of the rail or shaft.
