1) Cold-packing method puts the imported bearings in a mixture of dry ice and alcohol (or gasoline); it cools agilely; its outer diameter is shortened and it is quickly loaded into the main hole of the mainframe. Because the bearing steel usually has low temperature embrittlement tendency ; should avoid the temperature dropped below 500C. This method works well; but the cost is high; so as long as it is only necessary.
2) The hot-packing method heats the bearing housing to make the seat LB grow to facilitate the installation; this method is especially suitable for light metal bearing housings; for example, aluminum alloy bearing housings; however, the cost is still high; only when necessary Regarding the chaotic bearing housing; to avoid deformation and accuracy when heating.
3) The inclined bearing device method is large and the outer ring has a large interference bearing; for the convenience of the device; the outer ring and the bearing housing hole are made with a small taper; the device is fitted by the taper of the two sides. And use the end cover to manipulate the pushing amount of the outer ring; the interference is within the reserved range; and the frictional resistance of the end face of the end cap to the outer ring end also helps to fix the outer ring; avoiding the seizure activity. The bearing of the device is especially convenient.
Usually SKF imported bearings:
