For heavy loads, usually in conjunction with light load and normal load is tight. Loads heavier, combined with interference should be higher.
Bearing device, dismantling approach should be based on the SKF bearings structure, size and nature and cooperate with oil-free bearing parts. Thus, in the discussion of the design and installation of Assembly components is plentiful. Devices in accordance with the specifications. Tasks of the project are as follows: normally specifications
(1) the bearing inner ring and shaft are tight fit, and the shell of the outer ring for a loose fit, free press put the bearing pressure on the bearing, then put the shaft with bearings into the housing, mounting pad on a oil-free bearing surface when a soft metal Assembly casing information (copper or flexible steel pipe). Assemble bushing inner diameter should be slightly larger than the shaft diameter, diameter outer diameter is smaller than the inner diameter of the bearing flanges, to avoid pressure on the stick. Large numbers of devices FAG bearings in the casing on the handle.
(2) the bearing inner ring and shaft, and the shell holes in the outer ring are tight fit, assemble the casing surface should be made at the same time pressing the bearing ferrule end face both inside and outside the ring or disc and fitting a casing, the pressure on both reached the inner and outer rings, pressed into the shaft and NSK bearings shell.
Such devices special collection for self-aligning radial bearings with spherical device.
(3) for tight fit and shell holes in the outer ring of the bearing, inner ring and shaft for a loose fit, you can press the bearing into the shell, then assemble the casing should be slightly smaller than the outside diameter of the shell-hole diameter.
(4) the heating device, charging the former bearing or TIMKEN bearings that can go into the fuel tank or in a special heater evenly heated to 80~100℃ (should not exceed 100 ° c).
Quality of bearing cage that was very good, but in the day-to-day running of oil-free bearing, incorrect manipulation will reduce the life of the bearing cages, or even cause it to break. Installation is not in place, tilt, excessive interference prone clearance reduction, exacerbating friction heat, soften the surface, formed the abnormal falling off prematurely, with flaking extension, peeling off entering the retainer Pocket Hole, causing cage run blocking and creates additional load, exacerbating the cage and wear, this cycle of deterioration, it may result in cage fracture.
INA bearings play is in a poor state, formation of adhesive wear, deterioration of the surface condition of work, adhesive wear of tearing into the cage, cage abnormal load, potentially causing cage fracture. Creep sliding phenomenon of rings, the mating surfaces without sufficient interference, close to the loading point to move because of the slide, ring shaft or housing in a circumferential direction position deviation
