Spherical roller bearings are double row, self-retaining units comprising inner rings with two raceways inclined at an angle to the bearing axis , outer rings with a common spherical raceway, spherical rollers, cages and in certain designs also internal guide rings or center rings. The bearings can also be sealed.

Due to the spherical internal shape of the outer ring and spherical rollers, the spherical roller bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. They can accommodate both heavy radial load and axial loads.

Product Features

Load capacity is larger

Good impact resistance

Can bear a greater axial load

The operating temperature of the bearing is low

Can adapt to the requirement of high speed

Symmetrical drum roller freedom combined with concave outer ring groove plate. 

Cage:

CC: Steel plate stamping

CC type bearing inner ring is the feature of no guard and adopts the stamping steel cage,

CA: Brass cage

CA model, XKTE bearing characteristics of the inner ring both have guard cage and used car system entities

Application:

crusher,

Conveyors, 

railway vehicle axle,

Papermaking machinery,

Vibrating screens,

printing machinery,

Shakers,

Speed reducers transmissions,

and other heavy machinery.

Factors for the corrosion to the spherical roller bearing

The corrosion of the spherical roller bearing is caused by many internal and external factors as follows:

1. The chemical element and structure of the metal material itself;

2. The degree of finish of the metal surface;

3. The element and pH value of the liquor which contacts with the spherical roller bearing;

4. The environment temperature and humidity;

5. Various environmental media that contacts with the spherical roller bearing.

The sweat of the human being is a kind of salty, colorless and transparent liquid which shows faintly acid, and its pH value is among 5 to 6. The sweat includes not only the elements of Na, Ka, Ca and Mg, but also a few organic acids such as urea, lactic acid and citric acid. So when the sweat contacts with the spherical roller bearing, it would form a layer of sweat membrane on its surface, and the sweat membrane would corrode the spherical roller bearing. It is unavoidable for man to sweat, so we must prevent the sweat from corroding the spherical roller bearing, and we require the production personnel wear gloves or professional tools to operate the spherical roller bearing.

We should wash the spherical roller bearing according to the condition and environment to choose proper method. We could use the dry compressed air or dryer to dry the spherical roller bearing after the wash, and of course, we could also use clean gauze to do the drying.

We could soak the spherical roller bearing into the antirust grease to make it adhere a layer of the antirust grease. The thickness of the grease could be controlled by adjusting the temperature or viscosity of it. For some big size spherical roller bearing, we could not use the soaking method, we usually spray the antirust grease to the spherical roller bearing with the compressed air. As to this method, we must adopt thorough fireproof measure to ensure the safety of the production personnel and the spherical roller bearing.

FAQ:

I couldn't find a design to fit my application in your catalog. Can you help me design a bearing?

Yes, technical expertise is available to assist you with engineering design for custom products. Available options include, but are not limited to, custom rings, retainers, balls, shields, lubricants, and packaging. We look forward to working with you to satisfy your rotary motion requirements.

What causes bearing noise?

Bearing noise is a function of both the bearing and the way it is used. Some external factors that affect bearing noise include lubricant type, excessive bearing load, and improper installation. Once the abnormal noise occurred, you can contact our engineers, we will help you find the reasons and provide the appropriate solutions.

What is the difference between using a shield or a seal as a ball bearing closure?

Shields or seals are often installed to retain lubricant and to prevent contamination from entering the bearing. While a shield contacts the outer ring and does not come in contact with the inner ring, the seal generally comes in contact with both the inner and outer rings. Torque or drag is lower with a shield than with a seal. Alternately, the seal provides a higher degree of protection from contamination. Shields and seals are available in a variety of materials and configurations.

XKTE developed a serious of sealing methods for different applications. Please contact a XKTE engineer for technical assistance with any special requirements.
