Oil-free self-smooth bearings are also known as composite bearings, oil-free sliding bearings, self-smooth bearings, etc. This series of products is based on excellent low-carbon steel plate, center sintered bimetal bearing spherical bronze powder, externally rolled mixture of PTFE and lead, rolled from a sliding bearing. It can be used in various mechanical sliding parts, such as gear pumps, hydraulic self-lubricating steel sleeve components, pneumatic components, printing presses, textile machines, tobacco machines, fitness machines, hydraulic pallet trucks, micro-motors, automobiles, motorcycles and agroforestry. Machinery, etc., its adaptability, wear resistance, oil-free bearing factory, trust will become a professional leading commodity in the near future.
The characteristics and advantages of oil-free smooth bearings are:
1, no oil smooth or less oil smooth, suitable for places that can not be refueled or difficult to refuel, can be used in maintenance or less maintenance.
2, with appropriate elastoplasticity, can spread the stress on a wider touch surface, improve the bearing capacity of the bearing.
3, good wear resistance, small conflict coefficient, long service life.
4, in the operation process can constitute a transport film, to maintain the role of the grinding shaft, no biting phenomenon.
5. Near the static motion conflict coefficient, the flaw at low speed can be eliminated, and then the accuracy of the machine operation can be ensured.
6, can reduce the vibration of machinery, reduce noise, prevent pollution, improve working conditions.
7, thin wall structure, light weight, can reduce the mechanical volume.
8. The hardness requirement of the grinding shaft is low, and the shaft without the quenching and tempering can be used, and then the processing difficulty of the related parts is lowered.
9, the reverse side of the steel can be plated with a variety of metals, can be used in corrosive media.
Gutter smooth bearing series
The gap is smooth bearing, said abroad. The product is made of steel plate as the base, sintered spherical tin bronze powder as the center layer, and the surface is rolled with modified polyacetal and has oil storage pits and rolled into a sliding bearing. The thickness of the plastic surface of the product is 0.5mm, which has a good wear-resisting function and can work normally under the condition of less oil or gap oil. It adapts to the operation under normal temperature conditions and low-speed heavy-loading places to replace the traditional copper sleeve, which reduces the cost and extends the service life.
Application features:
1, good load bearing, outstanding wear resistance.
2. It is suitable for rotating motion, shaking motion under high load and low speed, and frequently opening and closing under load, which is not easy to form a fluid dynamic smooth.
3, in the smooth conditions of the gap can be long-term no oil maintenance, and the oil in the layer to make the bearing life is longer.
4. The outer plastic layer can leave a certain margin during processing and molding. After being installed into the seat hole, it can be processed by itself to reach a very good installation scale.
5. The commodities are mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment, etc.
Solid mosaic self-smooth bearing series
The solid inlaid self-smooth bearing series is a self-smoothing made by inserting a fine and appropriate hole in the metal collision surface of the bearing base, and then inserting a solid solid smoothing agent with a common self-smooth function in the hole. Bearing. The bearing summarizes the respective advantages of the metal matrix and the extra-smooth smoothing data, breaking through the limitations of the usual bearing relying on the smoothness of the oil film, and is particularly suitable for oil-free, high temperature, high load, low speed, anti-fouling, anti-corrosion, anti-radiation, and It can be used under the special working conditions of water or vacuum solution to moisturize and the bottom can not add smooth oil film. This product is widely used in metallurgical rolling equipment, filling equipment, hydraulic turbines, steam turbines, instrumentation and mining equipment, ship machinery, textile machinery, shipbuilding industry, aerospace sails, etc., and also applies to general construction machinery.
