At present, most of the bearings used in various machinery industries are balls, needles and the like. Only a small part of them have adopted self-lubricating bearings. It is believed that in the near future, lubricating bearings will be incomprehensible, wear-resistant and economical. Advantages and become the leading product in the bearing industry. The following are the application characteristics and advantages of some self-lubricating bearings: oil-free lubrication bearing series
1. No oil lubrication or less oil lubrication. It is suitable for places that cannot be refueled or difficult to refuel. It can be used without maintenance or less maintenance.
2. Good wear resistance, small friction coefficient and long service life. 3. There is an appropriate amount of elastoplasticity, which can distribute the stress on the wider contact surface and improve the bearing capacity of the bearing.
4. The static friction coefficient is similar, which can eliminate the creep at low speed, thus ensuring the working precision of the machine.
5. It can reduce vibration, reduce noise, prevent pollution and improve working conditions.
6. The transfer film can be formed during the operation to protect the grinding shaft without biting.
7. The hardness requirement of the grinding shaft is low, and the shaft without the quenching and tempering can be used, thereby reducing the processing difficulty of the related parts.
8, thin wall structure, light weight, can reduce the mechanical volume.
9, the back of the steel can be electroplated with a variety of metals, can be used in corrosive media; has been widely used in various mechanical sliding parts, such as: printing presses, textile machines, tobacco machinery, micro-motors, automobiles, motorcycles and agricultural and forestry machinery and many more.
Introduction to boundary lubrication self-lubricating bearing series
1. Good load bearing and good wear resistance.
2. It is suitable for rotary motion, rocking motion under high load and low speed, and occasions that often open and close under load and are not easy to form hydrodynamic lubrication.
3. Under the condition of boundary lubrication, it can be maintained for a long time without oiling, and the oil is added in the overlayer to make the bearing last longer.
4. The surface plastic layer can leave a certain margin during processing and molding. After the assembly is pressed into the seat hole, it can be processed by itself to achieve a better assembly size.
5. The products are mainly used in automobile chassis, metallurgical machinery, mining machinery, hydraulic machinery, construction machinery, agricultural machinery, steel rolling equipment, etc. JDB solid inlaid bearing series JDB solid inlaid bearing series is a general-purpose basic product, which can adapt to high pressure, low pressure, high temperature, low temperature, oil lubrication, oil-free lubrication or water lubrication. The base of the product is high-strength brass, which doubles the hardness of the ordinary copper sleeve and more than doubles the wear resistance. Widely used in: light industrial machinery, heavy machinery, construction machinery, metallurgical machinery, conveying machinery, etc., such as: continuous casting machine, rolling mill, injection molding machine, paper machine, mold guide column, ship, machine tool and so on.
