NU209 Nachi Cylindrical Roller Bearing Steel Cage 45mm x 85mm x 19mm Made in Japan NU209 Nachi Cylindrical Roller Bearing, Steel Cage, Made in Japan, the NU209 inner diameter is 45mm, the NU209 outer diameter is 85mm, NU209 width is 19mm. Item: NU209 Cylindrical Roller Bearing Type: Nachi Cylindrical Roller Bearing Cage: Steel Cage Dimensions: 45mm x 85mm x 19mm/Metric ID (inner diameter)/Bore: 45mm OD (outer diameter): 85mm Width/Height/thickness: 19mm Size: 45 x 85 x 19 mm Quantity: One Bearing Dynamic load rating Cr: 46,000 N Static load rating Cor: 47,000 N Limiting Speed: Grease Lubrication: 7,500 RPM Oil Lubrication: 9,000 RPM Made in Japan Nachi 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 brass are used for bearings of large dimension or for high-speed applications.NU209 Nachi Bearings Steel Cage Japan 45x85x19 BearingsKit10248
