TIMKEN Bearing

We should not open the package until the installation because TIMKEN bearing has been processed by antirust and packaged. Besides, the antirust oil coated on the bearing has good lubricating performance, so TIMKEN bearing can be directly used for cleaning. However, in terms of instrument bearing and high-speed rotation bearing, we need to use cleaning oil to wash away antirust oil. Meanwhile, the bearing cannot be placed for a long time because it can easily rust.

During the inspection of shafts and shells, we need to clean the bearings and shells and confirm there is no scar or machining burr left. Also, we should absolutely confirm that there is no grinding agent, sand and chip in the shell. Method of installing TIMKEN bearing varies according to its bearing matching requirements and structures of bearing. Generally, inner ring often adopts over surplus fit since the bearing is mainly of axis rotation. When installation of shells, the bearing has more clearance cooperation and the outer ring has over surplus fit. Bearing often adopts the installation of pressing with the help of press machine or uses shrink fit method of installation. During the shrink fit installation, the moisture in the air will condense on the bearing surface, so we need some appropriate anticorrosive measures.

After considering degree of damage, mechanical property, importance, operation condition of TIMKEN bearing, we can decide whether the bearing can be used again.

The bearing cannot be used and need to be replaced by new TIMKEN bearing if it has the following defects during the inspection:
1. Any one of the inner ring, outer ring, sleeve, rolling element and the cage has crack or notch.
2. Rolling surface, raceway surface, wall and rolling element have obvious scratches, corrosion or damage.
3. The cage is apparently worn or the rivet is obviously loosening.
4. The inner diameter surface or the outer diameter surface has obvious creep.
5. The TIMKEN bearing has apparent discoloration due to overheat temperature.
6. Seal ring or dust cover of grease sealed TIMKEN bearings is greatly damaged.

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 ...
