UCP212 UCP213 UCP214 UCP215 Lubricated Spherical Ball Bearings With Top Screws

The outer spherical bearing is a specialized type of bearing, distinguished by its spherical outer ring surface. This unique design allows the outer spherical bearing to self-align and fit into the corresponding concave spherical part of the bearing seat.

As a result, the outer spherical bearing can automatically self-align and still function even when the shaft is deflected or misaligned. This ability helps the bearing to avoid any operational issues caused by installation errors or shaft deformations.

The primary function of the outer spherical bearing is to bear radial and axial loads, but it is generally not suitable for bearing axial loads alone. The structure of the bearing consists of a spherical outer ring, an inner ring, and rolling elements, such as balls or rollers, which are positioned between the inner and outer rings.

The rolling elements allow for smooth operation by reducing friction and transmitting loads. In summary, the outer spherical bearing is an essential component in many applications, particularly in machines with rotational motion.

Therefore, it is evident that outer spherical bearings play a vital role in ensuring efficient functioning of various machines and mechanical devices. Their self-aligning capacity makes them a highly reliable and useful type of bearing that can adapt to various external factors.

In conclusion, the outer spherical bearing's unique design feature, making it an ideal choice to withstand radial and axial loads, and it is an essential part of many different mechanical devices due to its role in transmitting power while reducing friction.

The outstanding characteristics of outer spherical bearings can be summarized as follows:

• Automatic self-aligning ability: The remarkable feature of outer spherical bearings is that the outer diameter surface of the outer ring is a spherical surface. This design enables the bearing to fit perfectly into the corresponding concave spherical surface of the bearing seat, thus possessing the ability of automatic self-aligning. In situations where the shaft is deflected due to load or the installation center line of the shaft and the bearing seat hole is relatively offset, the bearing can still function within its self-aligning range. This feature is beneficial in avoiding any impact of installation errors or shaft deformation on the operation of the bearing.
• Bearing radial and axial combined loads: Outer spherical bearings are commonly used to bear radial and axial combined loads dominated by radial loads. In general, it is not recommended to use them to bear axial loads alone during design.
• Double-layer seal design: Outer spherical bearings normally have a double-layer seal design, mainly because they are commonly used in harsh operating environments, for instance, agricultural machinery bearings. The double-layer seal guarantees that dust does not infiltrate inside the channel, thereby prolonging the service life of the bearing.
• Structural features: The inner diameter of the outer spherical bearing is a tapered inner hole with a ratio of 1:12, and it needs to cooperate with a tight sleeve when used. Some outer spherical ball bearings come with top screws and eccentric sleeves. Their application scenarios and performance characteristics are slightly different.
• Wide range of applications: Outer spherical bearings are extensively utilized in the industrial field. They are usually used in large machinery and equipment, heavy machinery, construction machinery, agricultural machinery, transmission equipment, mining machinery, etc.
• Other performance: Outer spherical bearings have qualities such as large load capacity, long service life, easy installation, and prevention of outer ring rotation. In harsh working environments, such as high temperatures, heavy loads, vibrations, and other conditions, outer spherical bearings can still maintain a stable working state.

The application scenarios of outer spherical bearings are vast due to their unique design and performance characteristics. In various industrial fields, outer spherical bearings play an essential role. Below are the main application scenarios where outer spherical bearings provide reliable service:
