The difference between oil-free bearings, self-lubricating bearings and composite bearings

Author:admin Date:2020-08-22

Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free lubrication bearing. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for heavy loads, low speeds, reciprocating or swinging situations where it is difficult to lubricate and form an oil film, and it is not afraid of water wash and other acid erosion. And scour. It is widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.
Self-lubricating bearings are divided into composite material self-lubricating bearings, solid-inlaid self-lubricating bearings, bimetallic self-lubricating bearings, and special material self-lubricating bearings. Different self-lubricating bearings can be selected according to different uses and industries.
Composite bearings are bearings that work under sliding friction. The composite bearing works smoothly, reliably and without noise. Composite bearing applications are generally under low-speed and heavy-duty conditions, or operating parts that are difficult to maintain and lubricate.
