INA bearing installation and removal methods, according to INA bearing structure, size and components with the nature and INA Bearing.
 
Installation, demolition of the pressure should be added directly in the file ring-side surface of a tight fit, not by rolling the body pass pressure, because this will cause indentation of the INA bearing surface, the impact of INA bearings working properly, and even make INA Bearing damage. INA Bearing cage, ring, dust cover and other parts are easily deformed, installation or demolition of INA bearings can not add pressure on those parts.
   
(1) INA bearing inner ring and the shaft is a tight fit to the outer shell to a more loose fit can be used presses INA bearings first press-fit INA bearings, and then shaft into the housing together with INA Bearing press-fit in the INA bearing end face of the pad assembly casing of a soft metal material (copper or mild steel pipes). Assembly casing diameter should be slightly larger than the journal diameter, outer diameter should be less than the diameter of INA Bearing inner diameter of the rib, to avoid pressure in the cage. A large number of INA Bearing installation plus a handle on the casing. When to make the installation of INA Bearing INA bearing bore and shaft centerline coincidence. INA bearings relative axis skew not only difficult to install, but will also cause the indentation, journal bending even make the INA bearing inner ring fracture. INA Bearing in place of missing or can not use the press, assembly casing and small hammer to install. Impact force should be evenly spread to the entire circumference of the INA bearing ring face assembly bushing by hammering the end should be made spherical.
   
(2) INA bearing outer ring and the shell holes for the tight fit of the inner ring and shaft loose with INA bearings would be pressed into the housing when the assembly of the outer diameter of the casing should be slightly less than the shell hole diameter.
   
(3) INA bearing inner ring and shaft, outer ring and the shell holes are a tight fit, assembly casing end should be made simultaneously pressed the INA Bearing inner and outer rings seal ring or disc and assembly casing. so that the pressure reached the inner and outer rings, INA bearings pressed into the shaft and shell. This installation method is especially suitable for the installation of automatically aligning spherical bearings.
   
(4) heating installation, the installation of the force required by the INA Bearing INA Bearing size and amount of interference with the size of the amount of interference in large INA bearings commonly used in hot-filled. Hot charging INA Bearing INA Bearing or detachable ferrule into the fuel tank or a dedicated heater uniformly heated to 80 to 100 ° C (should not exceed 100 ° C). Hot charging INA bearings require skilled operation skill. INA bearings removed from the heating tank or heater shall be immediately with a clean cloth (cotton yarn) to wipe away the traces of oil and fixtures of the INA bearing surface, and then placed with the surface of the front in one operation INA Bearing push to withstand the location of the shaft shoulder.
   
(5) in the cooling process should always be pushed tight, or the assembly casing with a hammer tapping INA bearings to make it try. Should be installed slightly rotating INA bearings, to prevent the installation of tilt or card dead. INA bearing outer ring and shell holes can also be a tight fit to the shell heating load INA bearings. Light metal manufacturing INA bearing in the case of a tight fit, may INA Bearing outer ring pressed into and damage the mating surfaces, then should INA Bearing heating.
