1. turns on lathe the pine fixed bearing seat the bolt.Dismounts together the INA bearing together with the bearing seat from the axis.The attention in opens an axis end in front of the INA bearing seat. Should loosen the axis another end I bearing seat bolt, in order to avoid the both sides INA bearing other vigor damages mutually.

2. first loosens the gib screw with in hexagonal head wrench which the INA bearing bias puts on, then puts on with the small iron rod insertion roof panel bias sinks the hole, goes against the axis hand of rotation to hit the pine eccentric wrap.

Very many people in install in the bearing uses improper install the method, causes the INA bearing the damage.Then how correct installment INA bearing? Hopes everybody more comprehensive understanding INA bearing the installment and the disassemblage:

Regarding the gap coordination INA bearing race, suggested spreads one in the fitting surface lightly to guard against the creeping motion corrosive, guards against between the fitting surface to have the friction corrosion.

390000 series outside spherical surface bearings are fixed through the biased set the bearing inner loop and the axis, the bias puts on in hexagon bolt plays the fastening role.In the service, many machine operators cannot disassemble this kind of INA bearing, therefore has the necessity to introduce disassembles 390000 series outside spherical surface INA bearing the technical main point and the matters needing attention:

The correct installment, regarding the INA bearing use is extremely important.Hoped everybody can use correctly in later use installs the method.

When installs, may act according to its type and the size, methods and so on selecting mechanism, heating or hydraulic pressure carries on.Installs when exerts the action to the INA bearing, cannot transmit through the rolling body from a bearing race to another INA bearing race, otherwise possibly can create the damage to the roller conveyer.But in any situation, all may not rap the bearing race, the retainer, the rolling body or the seal directly.
Installment

3. installs the eccentric wrap.First the eccentric method in on the INA bearing inner coating eccentric stair, and screws tight with the hand along the axis hand of rotation. Then again or withstands the small iron rod insertion the bias to put on sinks the hole. Raps the small iron rod with the hand hammer along the axis hand of rotation. Causes a biased set of installment to be reliable, finally locks in hexagon bolt which the bias puts on.

4. fixed INA bearing seat bolt do not have to screw tight first, must let the bearing coat in the INA bearing seat internal energy rotation.Again fastens the bearing seat bolt.Similarly installs on the identical root axis another end bearing and the place, rotates the axis several, after lets INA bearing itself adjust the position automatically.

5. spreads the lubricating oil in the bearing seat and the bearing fitting surface, loads the INA bearing in the bearing seat.Then will assemble the INA bearing and the INA bearing seat will wrap together on the axis. Pushes to needs the position to carry on the installment.

6. installs in front of the INA bearing toward the axis on, must tear off the INA bearing coat first the set pin, simultaneously journal surface polish smooth clean, and spreads the oil in the journal place to guard against rust the concurrently lubrication (to allow bearing to have slightly rotation on axis).
　　
1st, ventilator on dust clear clean, avoids in the installation process to have the dust to enter in again the bearing;
　　
2nd, seals the bearing does not do the rubber to tear down, takes on the lower shaft the card to sell;
　　
3rd, dries the bearing in oil residue with the clean tissue paper or the soft cloth only, then also scratches the shaft lever cleanly;
　　
4th, joins in the bearing the butter, the principle is rather few not many in order to avoid affects the rotational speed seriously;
　　
5th, cuts again the can aluminum skin sells according to the bearing card the outer diameter to cut equally greatly a disk, and dug one in among just to be possible to pass through the shaft lever the eyelet between, fronted it in the bearing and the card sells, reduced the bearing end motion and the parallel motion distance.If the gap is big, must fill up several Canada thick only then good, causes the bearing the shuttle to be away from below 0.5mm;
　　
6th, seals the oil seal, adds on the butter, finally installs the ventilator reveals the card.Joins the power source to try, you can discover the sound have been slightly many, moreover as the matter stands at least may use for 2 years.But needs to remind, although sound small, but because the manual precision is limited, the rotational speed can drop slightly.
