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.

Some issues about the life time of the conveyor bearing

The life time of the conveyor idler relies on the quality and working condition of the conveyor idler bearing, so increase the life time of the conveyor idler bearing is very important. We must ensure good sealability for the work space of the conveyor idler bearing.

It exists the matter for the breath of the conveyor idler while it is working, that is to say, the gas inside the conveyor idler would escape while the working temperature is high, and that of which would shrink while the working temperature is low. At this time, if the sealability of the conveyor idler is not good, the gas or liquid near the sealing lip would enter the conveyor idler bearing, and if this has occurred for a long time, some harmful substance to the conveyor idler bearing such as the condensate water, would increase gradually to make the lubrication grease lose efficacy, thus to damage the conveyor idler bearing and shorten the life time of it.

This case would be more and more serious with the increase of the conveyor idler bearing´s rotate speed. So we have developed an all-sealed structure for the conveyor idler bearing with multiple sealing lips to cut off the connection between the conveyor idler and the outside. Furthermore, the gap between the bottom hole of the conveyor idler bearing base and the hole of guiding ring should be controlled to a small extent, and this could also increase the sealability of the conveyor idler 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.
