NACHI Bearing

NACHI bearing can be divided into the following types according to its size:
(1) Miniature size bearing which the range of nominal outer diameter size is below 26mm.
(2) Small size bearing which the range of nominal outer diameter size is 28 to 55mm.
(3) Small and medium size bearing which the range of nominal outer diameter size is 60 to 115mm.
(4) Medium and large size bearing which the range of nominal outer diameter size is 120 to 190mm.
(5) Large size bearing which the range of nominal outer diameter size is 200 to 430mm.
(6) Oversize bearing which the range of nominal outer diameter size is 440 to 2000mm.
(7) Heavy large bearing which the range of nominal outer diameter size is above 2000mm.

Also, NACHI bearing can be divided into the following types according to its bearing load of different directions:
①Radial bearing which bears radial load.
②Thrust bearing which bears axial load.
③Radial thrust bearing which bears radial and axial load.

In addition, NACHI bearing can be divided into two categories which are the rolling bearing and the sliding bearing according to its friction property.

Main Products
  • Spherical Roller BearingsSpherical roller bearing locates between the inner ring with two grooves and the outer ring with a spherical surface. The product assembles the drum-shaped roller. It has two rows of rollers mainly bearing radial load and the axial load in either direction. Our product has a high radial load capacity which is especially suitable for heavy load or vibration load. But it is unable to bear the pure axial load.
    Spherical roller bearing has good aligning performance and can compensate the coaxial error due ...
  • Tapered Roller BearingsTapered roller bearings consist of inner ring, roller, cage and outer ring which can all be installed and separated respectively. The product can withstand heavy radial and axial load, and it can be divided into single row tapered roller bearing, double row tapered roller bearing and four row tapered roller bearing according to the row number of roller. The types of bearings produced by our company are as follows:
    302 series: 30202 to 30256 ...
