Accordance the NTN bearing structure, size and bearing components with nature may be. Therefore, adequate research in the design and installation of the assembly department. To be installed in accordance with the stan dard. The task of this project are as follows: the usual standardbuy bearing
In NTN bearings installed before, you should use appropriate measurement tools on the design drawings and technical requirements, check the shaft and the housing bore and the relevant parts of the processing quality (such as dimensional accuracy, shape accuracy and surface roughness).
Assembly on the surface of the shaft and the housing bore any bumps, burrs, rust, or solid particles (such as debris, sand, mud), exists NTN Bearing installation difficulties, not only will make installation location is incorrect, and solid particles such as drop will play a grinding role into the bearing, NTN Bearing rotation can wear a work injury or abrasions bearing surface, so before installation must be carefully inspected, as found in the above-mentioned defects should be corrected. For example, the use of oil file to remove the burrs, raise d touch marks, rust and polish with fine emery cloth, clean the solid particles, dirt, etc. Another example.
The mating surfaces should be cleaned with clean gasoline, kerosene, toluene or xylene solution, and wipe dry with a clean cloth, and then coated with a thin layer of lubricant This will allow the installation more convenient.
The NTN Bearing inner ring and the shaft is a tight fit, the outer ring and the housing as a more loose fit, available presses the bearing press-fitted on the bearing, the shaft is then loaded into the housing together with NTN Bearing press fitted in the bearing The end surface of the pad assembly sleeve of a soft metallic material (copper or soft steel pipe). The assembly casing diameter should be slightly larger than the journal diameter, outer diameter should be less than the diameter of the bearing inner diameter wall, in order to avoid pressure in the cage. A large number of installed NTN bearings plus a handle on the casing.china bearing company
NTN bearing inner ring and the shaft, the outer ring and the housing hole is a tight fit, assembly ferrule end face should be made of the end face of the inner and outer rings of the ring while pressing the bearing or sleeve with a disc and assembly, the pressure at the same time spread to the inner and outer rings, the bearings are pressed into the shaft and housing. This installation method is particularly suitable for the installation of the self-aligning radial spherical bearing.
The NTN bearing outer ring and the housing bore is a tight fit, to the inner ring and the shaft is loosely fitted, and the bearing is pressed into the housing, and then assembly casing outer diameter should be slightly less than the diameter of the housing bore.
Heating installation, NTN bearings or bearing rings separable hot charging into the fuel tank or dedicated heater evenly heated to 80 ~ 100 ℃ (should not exceed 100 ° C).steel ball bearing
