Cylinderical roller bearing NU208

roller bearing and the raceway crown used it to design modification to eliminate the edge of the stress and improve bearing life. bearing Cylindrical roller bearings
DF wall design of a certain angle, so the bearer of the axial load greater than the more conventional design for NSK bearings 
The feature of the  Cylindrical roller bearings:   
No inner or outer wall with wall cylindrical roller bearings
NU-cylindrical roller bearings, its outer wall with two on, and no inner wall. N-type cylindrical roller bearings, at two of its inner wall, and no outer wall.
NU and the N-type cylindrical roller bearings, in a certain range relative to the bearing axis to allow me to make axial displacement of two-way, that could take the shaft caused by thermal expansion changes in the length, as it applies to non-bearing position. To be capable of sustaining their large radial load, but Cylindrical roller bearings can not afford to axial loading.

Cylindrical Roller Bearings NU208 40mm x 80mm x 18mm Steel Cage Made in Japan NU208 Nachi Cylindrical Roller Bearings, Steel Cage, here are the dimensions of the NU208, the NU208 inner diameter is 40mm, the NU208 outer diameter is 80mm, NU208 width is 18mm. * Item: NU208 Cylindrical Roller Bearings * Dimensions: 40*80*18 mm/Metric * Dynamic load rating Cr: 43,500 N * Static load rating Cor: 43,000 N * Limiting Speed: * Grease Lubrication: 8,500 RPM * Oil Lubrication: 10,000 RPM * ID (inner diameter)/Bore=40mm * OD (outer diameter D1)=80mm * Width/Height/thickness=18mm * NU208 Type: Cylindrical Roller Bearings * Cage: Steel Cage * Size: 40mm x 80mm x 18mm  * Quantity: One Bearing NU208 Cylindrical Roller Bearings Construction of this roller bearing type is the simplest of all radial roller bearings. This bearing type is often used in high-speed applications. Because the inner ring, outer ring, and rollers are in line contact, this bearing type has a large radial load capacity. Various Cylindrical roller bearing configurations are: N,NJ,NF,NU,RNU : integral ribs (flanges) NH,NP,NUP,NUH : integral and loose ribs NN,NNU : double-row bearings Configurations having integral flanges or loose ribs on both the inner and outer rings can sustain a small amount of axial load. Since this bearing type supports axial loads as sliding action between the end of the rollers and flange faces, axial loading is limited. Double-row Cylindrical roller bearings are used for high-speed, high-accuracy applications such as; main spindle support for lathes, milling machines, and machining centers. Radial clearance of tapered-bore bearings can be adjusted during mounting of the bearing(s) onto the mating journal. Standard cages are pressed steel or polyamide resin. Machined cages of high-strength
