Sealed spherical roller bearing lubrication

Sealed spherical roller bearing lubrication

 

Before install sealed spherical roller bearing,its not allowed exceed 80degree temperature when clean or heat the bearing,sealed spherical roller bearing don't need lubricant when the working temperature under 70 degree and the speed is lower than half of the limited,if the bearing working under the high speed and high temperature situation,the bearings must be lubricated with Lithium based grease,the Plastic belt must be moved which covered the lubrication hole of the outer ring.

 

Sealed spherical roller bearing lubrication,there is only little amount lubrication grease,

we need inject the lubrication grease into the lubrication holes of the outer ring slowly,and meanwhile,move the bearing,make the new lubrication grease uniform distributed during the rollers and raceway of the bearings. what we need to attention is to avoid much pressure when injection ,to prevent damage to the sealing ring of the sealed spherical roller bearing.

The seals of Sealed spherical roller bearing

Sealed spherical roller bearing is special design of spherical roller bearing,this design is double contacted seals on the spherical roller bearing,the sealing ring are made of steel frame rubber which can anti-oil and abrasion resistant.

 

1. Nitrile rubber(NBR),spherical roller bearing suffix 2CS

2. Hydrogenated nitrile rubber(HNBR),Suffix 2CS5

3. Fluorine rubber(FPM),suffix 2CS2

 

Please note:

Under above 300 degree temperature ,the rubber seals will be release Poisonous gas,so please

use under normal working conditions and less 200 degree temperature.

 

The sealing ring is fixed in the groove of the outer ring.for smaller bearing,sealing ring will be step up by groove,for larger bearing,sealing ring can use fix in the groove by cramp ring,The seal lip contact on both sides position of the inner ring raceway side,its usefull seals for spherical roller bearing.

Sealed spherical roller bearing cage

Sealed spherical roller bearing is one kind of spherical roller bearing,also named sealed self-aligning roller bearing,this kind of bearing are widely used in heavy duty capacity applications,it consist of double row drum rollers and inner ring,outer ring and cages,most of the spherical roller bearing are made of high quality chrome steel as well as element,but cage has so many kind of design according to material and design,brass cage,pressed steel cage,nylon cage,it depend on different manufacturer to make sure the best solution for the application,so it can the reliable moving and long service life.

 

The most normal cage design of sealed spherical roller bearing is brass cage(CA) and Pressed steel cage(CC),it adopt NRB material seals to prevent the dusty away from the internal of bearing,its better design for lubricatioin than open spherical roller bearing,sealed spherical roller bearing can be working reliable under the temperature -40~120 ℃.

 

Advantage of sealed spherical roller bearing

* lower frictional torque compared to the competition

* environmentally friendly characteristics

* lower grease consumption and disposal costs

* no requirement for expensive relubrication systems

* reduced maintenance outlay

* simple reconditioning of series 240 and 241

* longer operating life of the bearing.

 

Sealed spherical roller bearing can be used in Continuous casting plant,Elevator systems,sealed spherical roller bearing can be tapered bore and cylindrical bore,this design can save cost for the customers,and decrease the maintenance of the machine,improve the working efficience.

Why sealed spherical roller bearing

Why sealed spherical roller bearing

Sealed spherical roller bearing is better lubrication function and working condition than spherical roller bearing,Full performance of its Feature,so it can extend service life than normal design,but this design must be use high quality seals to prevent lubricant leakage and dust,moisture or other contaminants invasion,our sealing can be divided into self lubrication and plus seals.

 

For sealed spherical roller bearing choose,we need to consider some major factors as follows

Bearing lubricant and types;Bearing working environment,The size of the space occupied,characteristics of the supporting structure of the shaft,Allowable angle deviation;The peripheral speed of the sealing surface; operating temperature of the bearing;cost of manufacture.sealed spherical roller bearing don't need to lubrication any more as usual.

When spherical roller bearing mounting,we must make sure to right adjust for friction and vibrating,it will be better than normal spherical roller bearing.under the sealed spherical roller bearing operating ,temperature,vibration and noise also under monitered,from this data ,we can see the condition of the sealed spherical roller bearing and machine,make sure the testing work and solve the problem in advance to prevent the machine accidentally pause,decrease the cost of repairment and improve the production and efficiency of the machine.Under the process of sealed spherical roller bearing,how to choose lubricant oil or grease is very important.
