NU style with double outerrid, and the outer ring, roller,cage can separate from the inner ring.


Bearings single row cylindrical roller, model NU203


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: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:Attention problems of cylindrical roller bearings
4, when the interference is large, the oil bath heating or inductor heating bearings can be used to install the heating temperature range of 80 degrees -100 DEG C, the maximum can not exceed 120 degrees centigrade. At the same time, the nut or other appropriate method is used to fasten the bearing so as to prevent the contraction of the bearing in the direction of width and to create a gap between the collar and the shaft shoulder. 5, single row tapered roller bearings installed, the final adjustment should be clearance. The clearance value shall be determined according to the working conditions and the magnitude of the interference fit. Test shall be carried out when necessary. Double row tapered roller bearings and pump shaft bearings have been adjusted for clearance at the factory, and no adjustment is necessary during installation. 6, the bearing should be installed after the rotation test, the first for the rotary shaft or bearing box, without exception, then the power for no load, low speed operation, and then gradually increase as the functioning of the rotation speed and load, and to detect noise, vibration and temperature, abnormal, should stop running and check. The running test is normal and can be used before delivery.
Q:Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?
I carefully read your question, I think the following talk about my views, this system from the point of view of the design, are questionable, at least the following several aspects of the design problem, put forward for reference only:1, the system does not have [oil seal], can only say that the design of the beginning of the consideration is somewhat lacking.2, [] general should choose roller bearing oil bath lubrication [], [] instead of grease, because the roller in the roller bearing [] [] in the grease, the grease has a strong crowding out of [], which leads to bad lubrication.3, [] grease generally rely on the mechanism of working temperature Shenglai improve grease liquidity, but need to have [] to seal and prevent the overflow of grease, no seal mechanism design [] summary, this place is only [] However, boundary lubrication, boundary lubrication [] [generally used for oil lubrication], [grease] rather than
Q:Why are cylindrical roller bearings suitable for traveling support?
Should be the inner ring and the outer ring without the edge of the can do moving support. Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings.
Q:Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?
This is the simple cylindrical roller bearing rolling body is cylindrical roller, divided into full (no fixed retainer) and belt retainer 2 categories, because the rolling roller, so the axial bearing capacity relative to the ball bearing to be bigger.
Q:what does that mean? Please enlighten master, thank you.
Cylindrical roller bearingN216E stands for the bearing retainer as a steel cageN216EM stands for the bearing holder as brass holderThe material of the cage is different (the structure that holds the roller in it for a long time)
Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
The processing of the mating surface, especially the mating surface, is not done in a single clamping. The use of the bearing seat also causes misalignment, such as a flange bearing seat or a vertical KOYO inlet bearing block. As the work load causes the shaft to bend and deform, and also causes the inner and outer ring of the bearing to tilt, it will also appear misalignment.The main products are: KOYO bearing rolling bearing, deep groove ball bearings, high precision bearings, self-aligning bearings, bearings, plane ball bearings, cylindrical roller bearing, linear guide bearing, ball screw bearings, miniature linear guide bearing, cross roller guide bearings, reciprocating rotary bearings, ball bearing slide bushing, group cam follower.
Q:Why should the main shaft be coupled with double row cylindrical roller bearings?
Because double row cylindrical roller bearings with high carrying capacity, high precision, separation, easy installation and disassembly, mainly used in lathes, milling machines, machining centers and other high-precision machine tool spindle. Hope to be of help to you.
Q:NSK cylindrical roller bearings EW/EM series of differences and characteristics
M international is called brass retainerThis can be a question, just ask, for reference only
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.
