Features: Usually there is a gap between the inner hole of this kind of bearing and the shaft. The inner ring of the bearing is fixed on the shaft with a jack wire, eccentric sleeve or adapter sleeve, and rotates with the shaft.
Function: The bearing with seat has compact structure, easy loading and unloading, perfect sealing, suitable for simple support, and often used in mining, metallurgy, agriculture, chemical industry, textile, printing and dyeing, transportation machinery, etc.
Does the installation of the seated bearing on the shaft require a shoulder, just interference fit?
Whether the shaft shoulder is needed or not depends on the situation, and the matching method also depends on the situation.
The user needs to be clear about two points.
1. The role of the shaft shoulder is not only to provide axial support, but also a dead positioning.
2. Interference fits are not tried at all times. For thin-walled hollow shafts, you have to calculate the allowable interference distance.
What kind of situations are there for example?
Assuming that a shaft shoulder is used, what is the structure? I can’t understand the structure in the brochure, is the shaft shoulder inside the bearing seat?
What structure to use depends on the application situation, and the application situation determines the structure, not just use what you want,
Theoretically, the position of the bearing cannot be moved after being stressed on the machine, so the owner said that the shaft shoulder is needed, depending on the force condition of the machine and the cost. The design of the right track must be shaft shoulder, positioning, dustproof and lubrication.
