Specification of Cylindrical roller bearings:

Cylindrical roller bearings belong to separable bearings, whose inner and outer rings are linearly contacted with rollers. They have small friction coefficient, bigger capacity of bearing radial load and are applicable to both bearing heavy load and impact load and high-speed rotation. Cylindrical roller bearings have the advantages of compact structure, strong stiffness, big bearing capacity, small deformation after loaded etc.

CNBM has already successfully developed split cylindrical roller bearings which can be freely installed at any time and any place, to meet the demand of driving and conveying rollway bearings at cooling area of continuous casting. CNBM also can provide special cylindrical roller bearings according to requirement of customers.

Product Application:

- Iron and steel metallurgical industry

- Medium and large motor

- Generator

- Combustion engines

- Machine tool spindle

- Speed reducer

- Loading and unloading machinery and all kinds of industrial machinery

Single row cylindrical roller bearings

- NU, N single row cylindrical roller beaings

NU type and N type allows axis relative the cage within the scope of certain to do axial movement, it would adapt for thermal expansion or installation error caused by the shaft and housing relative position changes, they suit to use for free end bearing. Because they can not limit shaft and the shell axial displacement, and can only bear the radial load.

- NJ, NF single row cylindrical roller bearings

Both NJ and NF can bearing single direction axial load in a certain extent.

- NUP single row cylindrical roller bearings

NUP type bearings with double outer rid, single inner rid and loose rid, this design is possible to limit the axial displacement of the shaft or the housing in double direction within the scope of the axial clearance. in addition they mainly used to bear radial load, also can withstand diameter, the axial union load. Therefore this NUP suitable for fixed end bearings.

- NCL…V single row cylindrical roller bearings

No outer rim but with double lock ring without cage cylindrical roller bearing.

The bearing no cage, roller number is more, and size of the same other cylindrical roller bearing is able to withstand the big radial direction load, but its limit rotational speed is low. The bearing inner ring and outer inseparable, cannot install respectively, can limit shaft or housing of the two directions of the axial displacement in bearing axial clearance within the limit.

Q: NSK cylindrical roller bearings EW/EM series of differences and characteristics: E international is called "reinforced type" load, also means to increase rolling bodyW international is called a steel cage

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 the Nu and N type NJ NUP cylindrical roller bearings bear axial force?: The answer upstairs is clear. Such bearings can not be designed with axial force. In use, the inner and outer rings of the bearing can have larger axial displacement, and the aim is to compensate the length change caused by the rotating part of the two bearing due to the temperature rise.

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: 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: Double row cylindrical roller bearings how to disassemble?: If it is replaced, use the flame to heat it quickly under the conditions permitted! 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.

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: 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!: In general, this kind of bearing does not use the bearing seat

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. Our factory uses the bearings of Changzhou Enke Bearing Co., Ltd., they have many kinds of bearings and meet various demands.
