TIANHE 2 23944-2CS sealed roller bearing are fitted with a large number of long symmetrical large-diameter rollers, capable of withstanding very heavy loads. Special structures of raceway surface as well as the best quality ensure spherical roller bearings the lowest friction including C and CA-bearing.
Compared with conventional spherical roller bearings, tianhe bearings run cooler. They are able to withstand heavier axial loads, or up to a higher speed.

- Q:What copper is used to produce plain bearings for machine tools?
- Under dry friction conditions, we design a pre - formed synovial membrane on the surface of the bearing to ensure that the solid lubricant is transferred to the dual parts in the shortest possible time, and an effective solid lubricant film is formed.
- Q:What are the main structures of radial plain bearings? What are their respective features?
- The integral type bearing has simple structureThe mounting surface of the flange type bearing is perpendicular to the central line of the bearing
- Q:When the sliding bearing works, does the Bush not rotate and the journal rotates?
- Yes, usually when high speed runs, the oil will form an oil wedge between the shaft and the Bush, not directly between the two.
- Q:What are the uses of sliding bearings and rolling bearings and their classification?
- East China bearings for surface and surface contact, reduce friction, rolling bearings for shafts in the hole rotation, reduce friction, classification more, go to 0, 9 kinds, anyway, is a lot of ah!
- Q:National standard for plain bearings

- Q:What are the automotive engine journal bearings?
- Also called white alloy Babbitt, tin based white metal used to reduce friction, but low fatigue strength, heat resistance, temperature exceeding 100 DEG C hardness and strength decreased significantly, the gasoline engine used to load. The outstanding advantages of copper lead alloy are its large carrying capacity, high fatigue resistance and good heat resistance. But the running in performance and corrosion resistance are poor. In order to improve its running in and corrosion resistance, a layer of soft metal is usually electroplated on the surface of copper lead alloy into three layers of structural bearings, which are mostly used in high strength diesel engines. Al based alloys include aluminum, antimony magnesium alloy, low tin aluminum alloy and high tin aluminum alloy. High tin aluminum alloy bearings containing more than 20% of tin are widely used in gasoline engines and diesel engines because of their better bearing capacity, fatigue resistance and antifriction performance. The soft coating refers to electroplated a tin or tin lead alloy on the antifriction alloy layer. Its main function is to improve the running in performance of the Bush and to be used as the protective layer of the antifriction alloy layer. When the Bush is in the free state, the distance between the outer ends of the two joint surfaces is larger than the diameter of the bearing bore, and the difference is called the opening of the bearing bush.
- Q:I need to use thrust bearings in the design, and the shaft is vertical. What should I use for this bearing? How should the structure be designed?
- LZ put it in detail and write down the actual conditions. Otherwise, I'll recommend all of the thrust bearings to you.
- Q:The sliding bearing consists of several parts. What are the parts?
- Sliding bearings (sliding, bearing) bearings that work under sliding friction. Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger. The shaft supported by the bearing is called the journal, and the part that matches the journal is called the bush. In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. Sliding bearing applications are generally under low speed heavy load conditions, or maintenance and lubrication of the difficult parts of the operation.
- Q:In what circumstances, lubricant viscosity should be smaller?
- In low load, high speed and low temperature conditions, choose low viscosity lubricating oil. In heavy load, low speed and high temperature conditions, the choice of high viscosity lubricating oil or extreme pressure and anti-wear additives lubricants.Lubricating oil is the main lubricant. The main physical performance index of lubricating oil is viscosity, which indicates the internal friction properties of liquid flow, and the greater the viscosity, the worse its flowability. Another physical property of lubricating oil is oiliness, which represents the adsorption ability of lubricating oil on the metal surface. The greater the oil, the stronger the metal adsorption capacity, the more likely the oil film to form. The selection of lubricating oil should take into account the bearing capacity, journal speed, lubrication mode, surface roughness of sliding bearing, and other factors.General principles are as follows:1, in the light load conditions, in order to reduce friction power consumption, low viscosity lubricants can be chosen;2. under heavy load or impact loading conditions, oily and big viscosity lubricating oil should be used to form a stable lubricating film;3. static or dynamic sliding bearings can choose a small viscosity of the lubricating oil; 4. rough surface or without running surface should choose high viscosity lubricants.
- Q:What conditioning calculations should be performed for non liquid friction sliding bearings?
- Non liquid friction sliding bearings can be lubricated by lubricating oil or lubricated with grease. A small amount of flake graphite or molybdenum disulfide powder is added to the lubricating oil and grease to help form a stronger boundary oil film and fill the rough surface to reduce wear.
