Quick Look! Lubrication, metal bearing differences
In a variety of machines, bearings are an indispensable existence, although it seems very inconspicuous, single may be this small bearing can determine the operation of the machine. Then today for everyone to introduce the bearings about the types and their differences.
Lubricated bearings
It is necessary to rely on the lubricating medium such as lubricating oil or its own self-lubricating properties to reduce friction, reduce wear bearings. It can work in the oil-free or less oil environment, and through the solid lubricant in the friction surface to form a transfer film to realize the lubrication.
Metal bearings
The most common are steel bearings, copper alloy bearings, etc., which mainly rely on the strength and hardness of the metal to withstand the load, with lubrication measures to ensure that its running performance.
Structural characteristics
Lubricated bearings
This bearing usually has some special design to ensure the lubrication effect, such as oil grooves, oil holes, etc., they are used to store and transport the lubricant. Self-lubricating bearings will also be inlaid or composite solid lubricating materials on the metal substrate.
Metal bearings
Generally consists of inner ring, outer ring, rolling element and cage and other components, rolling element for the ball or roller, etc., the structure is relatively more traditional and common to adapt to different loads and speed requirements
Applications
Lubricated bearings
Widely used in all kinds of mechanical transmission equipment, such as automobile engines, gearboxes, industrial machinery, rotating and sliding parts, etc., in the need to reduce friction, reduce wear and tear, and improve the transmission efficiency of the place are applied.
Metal bearings
Extremely widely used in the industrial field, like machine tools, motors, aerospace, rail transportation and other equipment with high requirements for load carrying capacity and precision
