Stainless steel aligning ball bearing S1202

There are two kinds of structure: cylindrical hole and conical hole, and the material of the cage is steel plate and synthetic resin. Its characteristic is that the raceway of the outer ring is spherical, with automatic centering, which can compensate the errors caused by different concentricity and shaft deflection, but the relative inclination of the inner ring and outer ring shall not exceed 3 degrees.

The aligning ball bearing is a bearing equipped with spherical ball balls between the inner ring of two raceways and the outer ring of a spherical raceway.

The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same centering function as the automatic centering ball bearing. When the shaft and housing bend, it can be adjusted automatically without increasing the bearing burden. Aligning roller bearings can bear radial load and axial load in two directions. Radial load capacity is large, suitable for heavy load, impact load. The inner diameter of the inner ring is the bearing of taper hole, which can be installed directly. Or install it on the cylindrical shaft by using a clamping sleeve and disassembly cylinder. The cage is made of steel plate stamping cage, polyamide forming cage and copper alloy.

It can bear large radial load and axial load at the same time. The raceway of the outer ring of this type of bearing is spherical, so it has the function of centering. When the shaft is bent or tilted, so that the relative inclination between the center line of the inner ring and the center line of the outer ring does not exceed 1° ~ 2.5°, the bearing can still work.

Aligning ball bearing bore cylindrical and conical two kinds. The taper of the cone inner hole is 1:2 or 1:30. In order to enhance the lubrication performance of the bearing, the annular oil groove and three oil holes are machined on the outer ring of the bearing.

Product features

It mainly bears radial load, but can also bear small axial load. The axial displacement of the shaft (housing) is limited within the clearance limit, and it has the function of automatic centering, allowing normal operation under the condition that the inner and outer parts are not inclined too much. It is suitable for the parts where the bearing seat hole cannot strictly guarantee the coaxiality.

Structure form

The aligning ball bearing with dust cover and sealing ring has been filled with proper amount of grease during assembly. It should not be heated or cleaned before installation and should not be lubricated during use. It is suitable for operating temperature between -30 ℃ and + 120 ℃. Main applications: suitable for precision instrument, low noise motor, automobile, motorcycle and general machinery, etc., is the most widely used type of bearings in the mechanical industry

Job requirements

For heavy loads, poor working conditions or special sealing requirements of the bearing configuration, you can use a built-in contact type sealed aligning roller bearing. The outer dimension of the bearing is exactly the same as that of the non-sealed bearing, which can be substituted for the non-sealed bearing in many occasions. The center adjustment Angle is allowed to be 0.5°, and the working temperature is -20℃~110℃. The bearing has been filled with an appropriate amount of lithium anti-rust grease, and grease can also be added according to user’s requirements. According to the difference between the inner ring and the cage, it can be divided into two basic types, C type and CA type. The characteristic of the C type bearing is that the inner ring has no rim and the cage is stamped with steel plate. The characteristic of the CA type bearing is that both sides of the inner ring have rim and the cage is made of vehicle. This kind of bearing is especially suitable for working under heavy load or vibration load. A bearing with a drum roller is arranged between an inner ring with two raceway and an outer ring with a spherical raceway
