Product Details
Model Number: NU2888EM Brand Name: BMT Key Specifications/Special Features: Cylindrical roller bearings are of high load capacity and can operate at high speeds because they use rollers as their rolling elementsThey can therefore be used in applications involving heavy radial and impact loadingThe rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrationsThey are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ringWith 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 bearingsThis enables them to absorb shaft expansion to a certain extent, relative to the housing positionNU and NJ type cylindrical roller bearings produce high performance results when used as free side bearings because they possess the required characteristics for that purposeNF 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 bearingIn applications where heavy axial loads have to be supported, cylindrical roller thrust bearings are the most suitableThis is because theyare designed to contain shock loads, are stiffand the axial space required is littleThey only support axial loads that are acting in a single directionThese roller bearings can be separated and are easy to mount as well as dismount

10Physical 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
