Product Description



What is a  Cylindrical Roller Bearing?

Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.


The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.


More information

With the absence of ribs, either the inner or outer ring will move freely so as to adjust to axial movement hence can be used as free side bearings. This enables them to absorb shaft expansion to a certain extent, relative to the housing position.


NU and NJ type cylindrical roller bearing produce high performance results when used as free side bearings because they possess the required characteristics for that purpose. NF type cylindrical roller bearing also supports the displacement of the axial to a certain extent in both directions and therefore can be used as a free side bearing.


In applications where heavy axial loads have to be supported, cylindrical roller thrust bearings are the most suitable. This is because they are designed to contain shock loads, are stiff and the axial space required is little. They only support axial loads that are acting in a single direction.


Detailed applications

Specifically, our cylindrical roller bearings can be used in industrial transmission, automotive, electric motor, generator sets, elevating machinery, machine tool spindles as well as internal-combustion engines, etc.



These roller bearings can be separated and are easy to mount as well as dismount.

10  Physical Characteristics: 

      1)  Cylindrical roller bearing can be separated by single row,double rows and four rows.

      2)  This kind of bearing can be submitted to high radial load and some axial load.

      3)  The rolling element of cylindrical roller bearing is cylinder,the two ends of the external lines have the corrective slope which can eliminate the contact stress.

      4)  NN and NNU design cylindrical roller bearing have high rigid and apply to machines such as millings.

Q:The electric flat car bearing is a bearing? Which type? What's the name? No search
Look at the picture. It looks like an outer ball bearing. It belongs to the UCP series
Q:Where there is UCFC bearings CAD drawings to download
CAD drawings do not have detailed parameters, I have Baidu space album inside!
Q:How to remove bearing seat?
The first fixed bearing seat, then stick latte from inside the bearings hole through the other end pry bar, slowly again gently. You can pull it down.
Q:(seat) note bearing bearing bearing lubrication domestic installed outside the sphere?
Two, check the size of relevant parts and finishingThree, installation method of the spherical bearing should be installed according to the bearing structure, with the properties of size and bearing components and pressure should be added directly in a tight fit to ring face, shall not pass through the rolling pressure.
Q:UCPK UKP is not mounted ball bearings
No, the seat of these two bearings is different
Q:Technical parameters of ball bearing to where to download Thank you
Here are some related things. Look at it! Here's the download address!Standard number: GB/T 7809-1995Standard Name: ball bearings, ball bearings, external dimensions, dimensionsStandard status: currentEnglish Title: Roliing for insert bearing-Boundary dimensions BearingsHousingsAlternatives: GB, 7809-1987Date of implementation: 1996-8-1Promulgated by the State Bureau of Technical SupervisionBrief introduction: this standard specifies the size and tolerance of the casting seat and stamping seat of the spherical spherical bearing used in the outer spherical surface bearing according to GB/T 3882. It is suitable for the design, manufacture and acceptance of the bearing housings.
Q:What is the maximum speed of spherical bearings
It depends on what type, small model, high speed, big point speed is relatively lowGenerally around 1500--3000 rpm
Q:With aluminum support base, cylindrical linear guide, sbr2o sliding bearing seat price, note: (rail 6 meters long)
Cheap Bajiushiyi meters, more than 100 points better one meter, 6 meters to a root of the freight costs, proposed two docking requirements is not high, the cost of shipping a lot cheaper than docking.
Q:Such as spherical bearings, if the installation size seat loose,
Mainly based on your work environment, generally do not go too far, too small, will affect the accuracy!
Q:How many bearings should be installed on the equipment?
When the nozzle is upward or downward, consider the convenience and operability of the refueling position of the grease gun.
