UCPA204 Pillow block bearing

UCPA204 Pillow block bearing is a kind of rolling bearing, which has inner, outer, rolling body and reinforcing plate and other parts. Wherein, the inner ring is spherical, the inner wall of the outer ring is spherical, and the rolling body is a spherical roller or a spherical ball. Bearing appearance is spherical, can withstand radial and axial loads, but also can withstand inclination load, Angle load and torque load.
According to different structural forms, the outer spherical bearing can be divided into radial type and thrust type. The inner and outer global-shaped radii of the radial spherical bearing are equal and can bear the radial load and the inclination load. The spherical radius of the inner ring of the thrust type spherical bearing is smaller than that of the outer global radius, and it can bear the radial load, axial load and inclination load.
Second, the working principle
Pillow block bearings are also different in terms of working principle according to different structural forms. Taking radial spherical bearings as an example, when the inner/outer ring is displaced, the trajectory of the ball will change, so that the bearing can bear the corresponding load. When the axial load is borne, the rolling element inside the bearing will move in the axial direction, thereby relieving the load through its own bending deformation. At the same time, the rolling element can also roll freely on the spherical shell to adapt to different angles.
3. Application occasions
Pillow block bearings are widely used in various mechanical equipment and construction machinery, such as construction machinery, mining machinery, metallurgical machinery, water pump, hydraulic machinery, cooling machinery, excavators, mold machinery and so on. In addition, the outer spherical bearings can also be used as bearings for sliding couplings, and meet the high-speed and high-load environmental requirements of large and medium-sized machinery such as agricultural machinery. As a kind of high-load rolling bearing, the outer spherical bearing has the advantages of strong load bearing capacity, long life, simple maintenance and high reliability.
In short, the pillow block bearing belongs to a kind of rolling bearing, which has been verified in a wide range of applications. We believe that in the field of mechanical transmission in the future, external spherical bearings such as reliable bearings will continue to play an important role
