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
Technical
Load capacity 140N/mm2
Temperature -195°C ~ +280°C
Speed limit 5m/s
Friction coef(u) 0.04~0.20
PV Limit(Dry) 3.6N/mm2 .m/s
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: while the automobile wheel shafts and reducer gears use rolling bearings?
- The lubrication of the crankshaft of an internal combustion engine is pressure type. It has lubricating grooves on its bearings, which can further lubricate the crankshaft. But the automobile wheel shaft and the reduction gearbox gear's rotational speed is low, therefore uses the rolling bearing. Still wantThe bearing capacity of rolling bearing is strong.
- 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: What are the most afraid of sliding bearings?
- Sliding bearings are surface contact, so between the contact surface to maintain a certain oil film, so the design should pay attention to the following problems:1, it is necessary to smooth the oil film into the friction surface.2, oil should be from the non load area into the bearing.3, do not make the whole ring oil tank in the middle of the bearing.4, such as oil tile, joint opening oil groove.5. Make the oil ring fully and reliably supplied to the oil.6, the filling hole not blocked.7, do not form an oil free flow zone.8, to prevent cutting off the sharp edges and edges of the film.
- Q: The service life of a sliding bearing can theoretically be infinite, but this is not necessarily the case because the conditions of use can not be ideal. I want to know how long the actual life of the sliding bearings is The longest sliding bearings that I have come into contact with are the bearings (dynamic lubrication) of two Japanese roller mill spindles, which have been used here for about 30 years without any repairs.
- Bearing life depends on the working environment, a lot of temperature.
- Q: Establishment of oil film bearing capacity of dynamic sliding bearing and several conditions to ensure full liquid lubrication
- There is only one condition for complete liquid lubrication: the minimum oil film thickness is greater than the sum of the roughness of the shaft and bearing table.
- Q: What are the advantages and disadvantages of rolling bearings?
- 3. The rolling bearing is compact in structure, small in size, light in weight and easy to install and disassemble. Each part of the rolling bearing realizes the standardization of size, which is not only beneficial to the production of the rolling bearing, but also to the interchange of the parts of the rolling bearing so as to make it easier to be repaired and maintained.4, most of the rolling bearings using bearing steel as the main material, plus standardization, serialization of parts design, more conducive to large-scale industrial manufacturing, quality stability guaranteed.
- Q: The oil release ring is in the mounting position of the sliding bearing
- It has the advantages of no refueling, simple maintenance and long service life. It has been widely used in related fields in recent years.
- Q: Hello, about the bearing problem. Sliding bearings are made of powder metallurgy. What kind of grease does it use?
- You say is the ultra high temperature lubricating powder, and thread anti card grease, the grease types include the following:The total synthesis of anti - thread copper card containing metal powder, grease, commonly known as golden oil, thread, assembly and seal for high temperature.The total synthesis of high temperature anti - white fat card, the connotation of non metal powder. Mainly used for high temperature lubrication, demoulding, assembly, sealing.Total synthesis - black thread sealing grease containing MoS2 powder for bolt thread, casing, drill pipe etc..At present, the product, the tiger head, hotolube and Kluber series of more complete, stable quality. The metallurgical powder you are talking about may be the first or the third. Please choose according to the use.
- Q: What are the technical requirements and precautions for the assembly of plain bearings?
- When the shaft rotates at a high speed, the shaft to the bearing with periodically varying load, sometimes accompanied by shock.
- Q: What are their respective priorities? Thank youThe sliding bearing is different from the rolling bearing, many categories, so many companies are doing the rolling bearing while passing sliding bearings, such as FAG; some do metal materials to sliding bearings, such as Japan datong. I hope the predecessors to enlighten.
- In fact, FAG does not produce plain bearings.FAG, INA, LUK is the three largest brand owned by schaeffler;ELGES plain bearings are an integral part of INA's products. (understood as IBM and association)ELGES is a professional manufacturer of joint bearing, cylindrical sliding sleeve, rod end bearings and sliding bearings manufacturers, located in Germany by Shi Hagen,
