How should bearings be cold installed？

There are many ways to install bearings, and the installation and disassembly methods vary depending on the type of bearing and the operating conditions. PPH Bearing specializes in various high-precision outer spherical bearings. Today, the PPH Bearing editor will talk to you about the topic of bearing cold installation. I hope it can be helpful to you.

1. When installing small bearings that do not fit too tightly, the bearing can be installed in the appropriate position by using a sleeve and gently tapping the sleeve with a hammer. When striking, it should be evenly applied to the bearing ring to prevent the bearing from tilting or tilting. Using some specially designed impact rings can make this method easier to use.

2. If the inner and outer rings of a non separable bearing are to be installed on the shaft and bearing seat simultaneously, it must be ensured that the same pressure is applied to both the inner and outer rings, and the contact surface between the installation tool and the bearing ring must be on the same plane. In this case, some special bearing installation tools can be used to ensure that the pressure generated during tapping acts on both the inner and outer rings of the bearing.

When installing automatic self-aligning ball bearings, if the bearing needs to be installed into the bearing seat, some specially designed installation rings can be used to prevent the outer ring from tilting and swinging. The rolling balls of some sizes of automatic self-aligning ball bearings protrude beyond the side of the bearing, so the design of the installation ring should avoid contact and damage to the rolling balls. Most self-aligning ball bearings are installed using mechanical or hydraulic methods.

3. For separated bearings, since the inner and outer rings can be installed independently, the installation process is generally simple. When installing the shaft and other components and the inner ring into the outer ring of the bearing seat, it is necessary to ensure that the inner ring is aligned with the outer ring to avoid scratching the raceway and rolling elements of the bearing.

When installing cylindrical and needle roller bearings with or without a blocking edge on one side of the inner ring, it is recommended to use some special installation sleeves. The outer diameter of the sleeve should be equivalent to the diameter F of the inner ring raceway, and the tolerance standard should be d10. PPH bearings
