Double row cylindrical roller bearings
The rollers of the double row cylindrical roller bearing are usually guided by two flanges of a ring.
Because this assembly part composed of cage, roller and guide ring can be separated from another
ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing can be easily
mounted and dismounted. Its advantages are obvious especially when there is interference fits
between the inner, outer ring and the axis, housing.
This bearing is usually subjected to radial load, only the single-row bearing with inner& outer rings
- NN double row cylindrical roller bearings
This kind of bearings with inner rid, no outer rid.This assembly part can be separated from another ring, and they have larger radial load capacity than other single row cylindrical roller bearings with the same size, but the axial or housing is free axial displacement, so this kind of bearings can only bear the axial load.
★ Product Features:
The rollers of the cylindrical roller bearing are usually guided by two flanges of a ring.
Because this assembly part composed of cage, roller and guide ring can be separated from
another ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing
can be easily mounted and dismounted. Its advantages are obvious especially when there is
interference fits between the inner, outer ring and the axis, housing.
This bearing is usually subjected to radial load, only the single-row bearing with inner& outer
rings flanges can bear small steady axial load or great intermittent axial load. It has a high
requirement on the processing of the fitting parts such as axis and housing bore, etc.
Cylindrical roller bearings are mainly used for:
- Iron and steel metallurgical industry
- medium and large motor
- combustion engines
- gas tuibine
- machine tool spindle
- speed reducer
- loading and unloading machinery and all kinds of industrial machinery
Double Row Cylindrical Roller Bearings Catalogue
- Q:Rolling bearing face to face or back to back on the use of cylindrical roller bearing pairs, the speed limit will be reduced? Please, thank you!
- Cylindrical roller bearings, applicable speed can be very high, check all kinds of high speed motorized spindle bearing configuration will know.
- Q:Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master
- This is a bit too small to understand, because different installation methods are different from each other. It is recommended that the landlord refer to the installation of cylindrical roller bearings, the above is very clear.
- Q:What are the differences between cylindrical roller bearings nu208m and nu208em?
- E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
- Q:Why does cylindrical roller bearings fail abnormally?
- 3, the rigidity of the shaft is poor, too large bending occurs under the load, and the span of the fixed end of the cylindrical roller bearing two is larger. When the temperature rises, the thermal elongation of the shaft causes the bending of the axle static property.4. The assembly surface falls into the hard particle or the dirt, the stress concentrates, to the open bearing pedestal when clamping, the cylindrical roller bearing ring clamp flat.
- Q:Thrust cylindrical roller bearings, the main use?
- Thrust cylindrical roller bearings, the main use? Thrust cylindrical roller bearings are mainly used in oil rigs, iron, steel, machinery and so on.
- Q:The Russian bearing suffix No. ZST is a cylindrical roller bearing
- Well, you have to write out the whole model. The suffix code is not used to distinguish the bearings, but it helps to explain the structure of the bearings and the material.
- Q:Is the nu240em cylindrical roller bearing split?
- No, nu240em cylindrical roller bearings are integral.Bearing type: cylindrical roller bearingNew model: NU240EMOld model: 32240EHInternal diameter (mm):200Outside diameter (mm):360Width (mm):58
- Q:For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12
- This is the outer ring and the inner ring can be separated, the bearings in the country can be produced, imported bearings are sold.Another model is up to your standard,Cylindrical roller bearings SL183008Semi position bearing, full cylindrical roller, dimension series 30M 0,31 kgqualityCr 66000, NBasic rated dynamic load, radialC0r 67000, NBasic rated static load radialCur 11200, NFatigue limit load, radialNG 6300, 1/minLimit speedNB 4300, 1/minReference speed
- Q:How to check the thrust cylindrical roller bearings?
- This data is the minimum axial load, not the maximum axial load.
- Q:Why cylindrical roller bearings can not bear axial load?.
- Bearing bearing axial force or radial force is determined by the structure of the bearing, thrust ball bearings are also called plane bearings, which are mainly used to bear axial force; cylindrical roller bearings can bear radial forces and are not suitable to bear axial force.
