NU series large stock bearing for sale cylinrical roller bearing NU252M

The NU1012, NU1012E, NU1012M1,NU1012ML,NU1012M cylindrical roller bearingsare separable bearings,the rollers are guided by the two ribs of bearing rings.The cage,rollers and guide ring are assembled to a unit, and can be separated from the other ring. These bearings are easy to be mounted and dismounted, especially inner and outer rings interference fit with shafts and housings.

The NU1012, NU1012E, NU1012M1,NU1012ML,NU1012M cylindrical roller bearing will working application: Cable Stranders,Worm gear, Screw Drives, Turbine engine mainshafts, Transmissions, large-size generators, machine tool spindles, axle boxes,bent axles of diesel engines, gearboxes, Mechanical presses, Electrical motors, Pumps and compressors, Traction motors for railway vehiches, Axle boxes for railway vehicles, Steel mills, And so on.

Something about Cylindrical roller bearings:

1 heavy radial and impact loading

2 less coefficient of friction

3 variations of structure

4 row cylindrical roller bearing feature high radial load because the rollers and raceway are in linear contact

5 The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft

   axial movement,to a certain extent, relative to the housing position

6 The NJ and NF types carry a certain degree of axial displacement in both directions so they    are also used as free side bearings

7 Our company mainly produce both single-row and double-row cylindrical roller bearings:

   Single-row cylindrical roller bearings (ID.20--1900)

   Double-row cylindrical roller bearings(ID.20--1500)

8 Moreover, we can manufacture these bearings according to customer's drawings and samples

Classifications:

N typebearing housing washer no guard, both sides of the inner ring has guard. Can allow shaft relative bearing between the axial two direction of displacement. NU type of bearing's outer two guard, inner ring no guard. Can also allow shaft relative bearing between the axial two direction of displacement. Therefore, this kind of structure is suitable for use as a floating end bearing.

NJ typebearing housing washer two guard, the inner ring of the unilateral have guard. May have a certain amount of unilateral axial load.

NF typeof unilateral have outer rim, the inner ring of the two guard. Also can bear a certain amount of unilateral axial load. Therefore, this kind of structure is suitable for single direction as the axial location bearing with.

NUP typebearing outer is two guard, inner ring side band (fixed) single guard, and the other side is separable flat ring. May have a certain amount of two-way axial load.
