NU style with double outerrid, and the outer ring, roller,cage can separate from the inner ring.
★ 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:How to check the thrust cylindrical roller bearings?
- Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
- Q:What does "cylindrical roller bearing" ENV mean?
- Cylindrical roller bearings, the basic model suffix ENV meaning:E: enhanced design with improved bearing load capacityN: the outer ring of the bearing is provided with a stopping grooveV: full installed roller (no cage)
- Q:The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!

- 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
- I don't know what you mean. The size of NUP2311E is: inside diameter, 55mm, outside diameter, 120mm height: 43
- Q:How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
- The purpose of the shoulder shaft is to limit the axial sliding, of course, as the thrust bearing, the main bearing capacity is the axial force, so the shaft shoulder size can be appropriately larger.
- Q:Can cylindrical roller bearings bear high temperature?
- Bearing is not high temperature grease is not high temperature, a grease temperature does not exceed 120 degrees, high temperature will lead to bearing lubrication performance, unable to work, in fact, the bearing itself can be high temperature resistant.
- Q:What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
- The convex roller refers to the basic cylindrical or conical roller with a continuous micro convex radian in the plane containing the roller axis, and the logarithmic curve roller is also a convex roller, which belongs to a full convex roller;Convexity roller refers to the plane containing the axis of roller in the outer surface of a continuous convex curved basic cylindrical or conical roller, roller is logarithmic curve convexity roller, roller is all convex; convexity roller refers to the plane containing the axis of roller in the outer surface of a continuous convex curved basic cylinder or conical roller,The logarithmic curve roller is also a convex roller, which belongs to a full convex roller; a modified roller refers to a roller that has a slightly modified diameter at the end of the outer surface to prevent the contact between the roller and the raceway.
- 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 themselves require that the applied speed can not be too high, especially in short axis applications
- Q:How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings
- 3, the bearing clearance in different conditions: the bearing clearance can be changed under different conditions, in particular, can be divided into: 1) the original clearance: the original bearing clearance refers to the complete installation in front of the machine after the bearings, the clearance in a free state of the. In fact, the original clearance is not to be measured by measurement, so the original clearance is often replaced by a test clearance. The inspection is in clearance inspection status, applied in measuring load conditions, clearance data instruments detection and, strictly speaking with the original bearing clearance is not the same, but little difference in the readings on the two in general, so it can replace each other without causing much error. 2) effective clearance: effective clearance, or work clearance, refers to the bearing in the installation of the host, in a certain load, to a certain temperature rise in a stable state of operation, bearings exist in the actual clearance. Obviously, the effective clearance is smaller than the original clearance.And 4, bearing clearance: clearance of bearing is to ensure that the bearings are to operate flexibly without blocking, but also requires that can ensure the bearing running smoothly, the bearing axis has no significant settlement, and the number of rolling elements bear the load as much as possible. Therefore, the clearance of the bearing has a great influence on the dynamic performance of the bearing (noise, vibration and friction) and the rotation accuracy, and the carrying capacity (wear and fatigue) of the bearing.
- 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.
