Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or dynamic loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.Self-aligning roller bearings are divided into two different structures according to the roller cross section shape: symmetrical spherical roller bearings and asymmetric spherical roller bearings.

Single row tapered roller bearing is a common rolling bearing, which is composed of an inner ring, an outer ring, a roller and a cage. Its structure is similar to a conical shape, which is why it gets its name.The contact points on the inner and outer rings are conical and suitable for bearing large loads in both radial and axial directions.

1.Cylindrical hole· With two rows of steel balls and a curved raceway in the outer ring, self-aligning ball bearings can be actively aligning· and can accept the point of view error between the shaft and the bearing seat. It is suitable for the working condition that simply shows the shaft deflection and the shaft error caused by different centers· Friction is the lowest of all rolling bearings· has only a small temperature rise even at high rotational speeds.2.

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.

Roller bearings are designed for extremely demanding applications and must support high loads, severe misalignment, environmental pollution, shock and vibration. Due to the highest load rating in the industry and production from factories near you, there is no reason to look for self-aligning roller bearings anywhere else.TypeCylindrical roller thrust bearingTapered roller thrust bearingSelf aligning roller thrust bearingSelf aligning roller thrust bearing is a kind of self-aligning bearing. In use, the maximum allowable shaft deviation is about 2 degrees.

The selection of appropriate construction machinery bearings is crucial to the performance and life of mechanical equipment. Ensure that the bearing meets the working conditions and load requirements, which can reduce the failure rate and improve the reliability and service life of the equipment. At the same time, regular maintenance, timely replacement of lubricating oil, cleaning and inspection of bearings can extend the life of bearings and reduce the possibility of failure.

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

CAM bearing is a kind of bearing, with a thick outer ring needle roller bearing and bolt combination structure; The bearing bolt is provided with X oil passage; The outer surface of the outer ring has a cylindrical shape and a spherical shape, which can be selected according to the actual application; Eccentric type can easily and accurately adjust the axis position of the bolt when installing the bearing, etc., generally used in automotive camshafts (is the shaft that controls the opening and closing action of the X-type engine valve)1, thick outer ring needle roller bearing and bolt combinat

Tapered roller bearings are suitable for bearing radial loads, unidirectional axial loads and radial and axial combined loads. The axial load capacity of tapered roller bearings depends on the contact Angle α, that is, the Angle of the outer ring raceway, the greater the contact Angle α, the greater the axial load capacity. Generally tapered roller bearings do not allow Angle errors, but the surface of the roller and raceway can be specially designed to allow 2'~4' Angle errors.

The outer diameter (OD) of the cam follower (stud or yoke) can be the standard cylindrical shape or be crowned. Crowned cam followers are used to keep the load evenly distributed if it deflects or if there is any misalignment between the follower and the followed surface. They are also used in turntable type applications to reduce skidding. Crowned followers can compensate for up to 0.5° of misalignment, while a cylindrical OD can only tolerate 0.06°. The only disadvantage is that they cannot bear as much load because of higher stresses.

When the rotary support bearing is working, the inner and outer rings realize relative rotation through the combination of rolling elements. When the external force acts on the bearing, the load is transmitted to the inner and outer rings, and is transmitted to each other through the rolling element, achieving the carrying capacity. At the same time, the rolling motion of the rolling element reduces the friction force and improves the rotation efficiency of the bearing.
