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:

Mining & Construction,

crusher,

Conveyors, 

railway vehicle axle,

Papermaking machinery,

Vibrating screens,

printing machinery,

Shakers,

Speed reducers transmissions,

and other heavy machinery.

The effects that lubrication has on the lifetime of the conveyor roller bearing

Lubrication has a very important effect on the lifetime of the conveyor roller bearing.

1. How to select the lubrication grease?

Here we simply introduce the way to select the lubrication grease for you. The lubrication grease is made of base oil, thickener and additive, it has great difference of feature for different types of lubrication greases, and they call different rotate speed, so we must notice that during the selection.

The feature of lubrication is maimly determained by the base oil. Generally speaking, the base oil of low viscosity is used in the environment of low temprature and high speed, while the high viscosity in the environment of high temprature and high load. The water tolerance of thickener determines the water tolerance of the lubrication grease. In principle, different types of lubrication greases cannot be mixed. And for more, it would have different effects on the conveyor roller bearing for using different additives even the thickener is same.

2. Is it necessary to wash the conveyor roller bearing before the instalation?

The conveyor roller bearing is smeared with slushing oil on its surface, we must wash it with clean petrol or kerosene, and then smear clean lubrication grease to use it. It has a great effect on the lifetime and noise of the conveyor roller bearing that whether the component is clean. But the all-sealed conveyor roller bearing does not need to be washed and add oil.

3. How to instal and remove the conveyor roller bearing?

We could not knock the surface of the conveyor roller bearing directly while instalation. We should do it with proffesional installing tools to make the conveyor roller bearing holding uniform pressure, it will be more smooth for the instalation if the surface of component is smeared with lubrication grease. Or we can put the conveyor roller bearing into the mineral oil to heat it to 80-90 degrees, and then instal it immediately. We must donot make the temprature exceed 100 degrees.

If you get into trouble while removing the conveyor roller bearing, we suggest you put hot oil onto the inner ring of it, that would make the inner ring swell.

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.
