Advanced search self-aligning ball bearing 2208
Double row self-aligning ball bearings have a sphere raceway in the outer ring and a double raceway in the inner ring. This feature give the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing. They are therefore particularly suitable for applications where misalignment can arise from errors in mounting or from shaft deflection.
Double row self-aligning ball bearings are mainly used to carry radial loads and light axial loads, but cann't carry pure axial loads

Application
1.PTFE and fibre can protect the shaft while in operation.
2.It is suitable for the machine required harmless to people because
of Lead-free.
3.Goodload capacity and anti-wear.
4.Bronze and steel have good thermal conductivity.
5.Anti-corrosion because of surface plating.
6.It is widely used in general machines,and suitable for food machine,pharmaceutical
machine,tobacco machine etc.It will subsitute SF-1 series bushings in future because of environment protection.
- Q: How is the oil groove of the plain bearing processed?Boring, milling, or other methods of processing?What's the difference between oil grooves with different inner diameters?
- 1, with the processing of internal thread processing. 2. Pull out with a broach. 3. Pull out with special machine tools.
- Q: What's the difference between plain bearings and oilless bearings?
- The sliding bearing has the following characteristics: 1, long service life, suitable for high speed; 2, can withstand the shock and vibration load; 3, high running precision, work balance, no noise; 4, simple structure, convenient assembly and disassembly; 5, large carrying capacity, can be used for heavy-duty; 6, non friction sliding friction bearing liquid. Loss of fluid friction; sliding bearing, rolling bearing friction loss and not much difference, but the design and manufacture of lubrication and maintenance requirements of high.
- Q: What are the aspects of the performance of plain bearing materials?
- The material selection of the sliding bearing depends on the form of failure. The main failure modes are wear and fatigue damage of bearings and shafts. The prevention of wear and fatigue damage of bearings and bushings is the key to the selection of bearings and bushings. The main considerations are as follows:Wear resistance and friction reduction;Running in (running fit);Hiding property;Compliance;Strength and plasticity;The heat transfer and good corrosion resistance;The process of economy, etc..
- Q: High speed heavy duty important sliding bearing, bearing material with tin base bearing alloy or casting tin bronze?
- 2, lead base bearing alloy, suitable for low speed heavy load, the price is much cheaper than tin, but it is not suitable for high-speed. But the performance is better than that of copper alloy.
- Q: Failure forms of plain bearings, failure forms of plain bearings
- 5. corrosion: oxidation of lubricant to acid substance corrosion.
- Q: What are the parameters that are generally considered in the dynamic characteristics of plain bearings?
- Hello, Chen Han Plain bearings mainly have the following parameters:Load;Linear velocity;Service temperature;Tensile and yield strength;Hardness;Coefficient of friction;PV value;
- Q: Are the motors sliding bearings at both ends?
- The electric ball of a small gasoline generator has only one end of a roller bearing, and the other end is supported by an engine shaft
- Q: What kind of lubrication is used for spindle bearings of important or precision machine tools?
- 2. universal grinder, internal grinder, grinding high speed grease for these two kinds of grinding roller bearing, the rolling bearing of high speed spindle, the spindle speed is 1000 ~ 20000r / min, according to the speed range, such as when the value is less than 1 * 106, choice of precision machine tool spindle grease (No. 3 high speed grinding grease) white grease or special grease. This kind of machine tool and bearing internal grinder similar rolling 3. universal thread grinder spindle, spindle rolling bearing structure for ball type, spindle speed range is different, such as spindle speed Y7520WDN universal thread grinder is 5745 ~ 18000r / rain, can choose 2 high speed spindle bearing grease, can also be No. 2 multipurpose grease. 4. rolling bearing gear grinding machine spindle gear grinder spindle speed, generally in the 1000 ~ 3000r / min, in the speed range, the rolling bearing can be lubricated by lubricating oil, also can be lubricated by grease, such as high speed spindle bearing grease No. 3 or No. 2 multi effect lithium base grease. Rolling bearings use N15 mechanical oil or 2 spindle oil lubrication, bearing noise, grinding head noise, grinding head temperature of 70~80 degrees, and the oil leakage is serious, bearing wear rate is high, affecting production. If the switch to general lithium grease, can eliminate the temperature rise, to avoid oil leakage, stable work, surface roughness from level 6 to level 7, and add the grease has been used to bearing scrap, can prolong the service life of 2~3 times of bearing. Improve the industry technology, can find some more and more school platform, such as Xin opportunity, or in the application market to try to search some metal processing related applications ~ hope to adopt.
- 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: Tilting pad radial sliding bearing which features
- The destabilizing force of the radial vortex, therefore, has high stability and can theoretically avoid the occurrence of the oil film shock (in fact, due to the damage of the bearings)In addition, the pad can swing freely and increase the support flexibility, also has the ability to absorb the shaft vibration energy and vibration damping is very good. The tilting pad has many advantages, but the complex structure, installation and maintenance more difficult, the cost is higher. The shortcomings of tilting padAlso, any questions, please continue to discuss with me
