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
flanges.
- 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.
★Product Application:
Cylindrical roller bearings are mainly used for:
- Iron and steel metallurgical industry
- medium and large motor
- generator
- combustion engines
- gas tuibine
- machine tool spindle
- speed reducer
- loading and unloading machinery and all kinds of industrial machinery

- 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
- Da means shoulder diameter, that is to say, the maximum shoulder size is 69mm, and the minimum is 64mm
- Q:Why does cylindrical roller bearings fail abnormally?
- Generally, the causes of abnormal failure of cylindrical roller bearings are as follows:1, cylindrical roller bearing manufacturing accuracy is poor, one end of the bearings with loose, and travel source is larger, bearing frame rigidity is poor. Or the bottom of the bearing seat is uneven.2, cylindrical roller bearings axis misalignment (misalignment) axis and the housing of the shoulder to the surface is not vertical, shell installation, bearing two or more holes, different axis.
- Q:Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?
- The utility model is suitable for occasions where the bearing requirement is higher.
- Q:How to check the thrust cylindrical roller bearings?
- This data is the minimum axial load, not the maximum axial load.
- Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
- The allowable deviation of 1, the inner and outer diameter, width and the width of the assembly allowable deviation 2, roller diameter and the outer round round in group 3, the diameter of the chamfer size bounds value 4, the width of the allowable rotation accuracy (momentum and rotating body beating related projects) 1, inner ring and the outer ring allows for radial and axial beating 2, inner ring 3, allowing the lateral runout of outer surface inclination to allow changes in volume 4, the thickness of the thrust bearing raceway permissible variation
- Q:What are the components of cylindrical roller bearings?
- Compared with the deep groove ball bearings of the same size, this kind of bearing has larger radial load capacity, and is also suitable for high-speed rotation from the structure.
- Q:Can you make it clear? I don't understand. Thank you for being here first.
- A rolling body is a short cylinder.The inner ring (or outer ring) of the bearing can be split.
- Q:Double row cylindrical roller bearings how to disassemble?
- The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
- Q:cylindrical roller bearings N210 20Deep groove ball bearings 6120, self-aligning ball bearings 1210, cylindrical roller bearings N210 in the same radial force conditions, the life expectancy of the three levels and how to compare? What is the cause of the high and low?
- Summary: the above three kinds of bearings, the service life in accordance with the order from high to low: deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings.
