As far as possible, the resultant force is applied through the axis of the outer spherical bearing seat, which requires the application point to be even, symmetrical and stable, and to apply force through the sphere or parallel to the axis. 

The size of the force should be stable and uniform, not suitable for impact, which requires the use of oil pressure or can apply a steady tension or pressure tools, really have to use hammer, but also through the copper sleeve and other relatively soft metal to buffer, as light as possible.It is best to hammer with a copper rod or hammer. 

Avoid applying force through the rolling body, which requires the inner ring (shaft ring) to apply force through the inner ring, the outer ring) to apply force through the outer ring. 

Drag force should be maintained to the proper extent, for example, when installing the outer spherical bearing seat, stop applying force when the outer spherical bearing seat is installed/just installed in the correct position, and ensure that the end face of the ring (washer) is against the seat hole or the shoulder end face of the shaft, neither too tightly squeezed nor not installed in place. 

1. Use the right tools

Avoid replacing existing tools with the right ones. 

2. Keep the outer spherical bearing seat and its surroundings clean

Even if the eye can not see the small dust, will also bring bad influence to the outer spherical bearing seat.Therefore, to keep the surrounding clean, so that dust does not invade the outer spherical bearing seat. 

3. Use with care

In the use of the external spherical bearing seat to give a strong impact, will produce scars and indentation, become the cause of the accident.In severe cases, cracks and fractures may occur, so attention must be paid to them. 

4. Pay attention to the corrosion of the bearing

When operating the outer spherical bearing seat, the sweat on the hands can become the cause of rust.Be sure to use clean hands and wear gloves if possible.According to the relevant data, the damage during the installation of the outer spherical bearing seat accounts for 20% of the damage of the bearing. How to reduce the damage during the installation of the bearing?This has become a big headache for users.
