Self-lubricating bearings are widely used at home and abroad for their unique performance and economy. The copper sleeve base adopts a high-strength and high-hardness copper alloy, which is more than twice as strong as the ordinary copper sleeve. The surface of the copper sleeve is drilled with graphite-based oil-containing solid lubricant, and the lubricating area is about 25%. When the bearing is running, a solid-liquid mixed lubricating film is produced to reduce the friction and greatly improve the copper sleeve. Its own performance. It can work normally under severe conditions such as heavy load, high temperature, impact load, reciprocating motion, water, and difficulty in refueling. Ordinary copper sleeves wear out due to oil film failure and can not be used. The product has a history of nearly ten years and has been widely used in various industries across the country. As the use of this product will become more and more widely used, it will definitely bring good benefits to the society.
