Sealed spherical roller bearing benefits

Sealed spherical roller bearing offer long-life performance,are very highly reliable under harsh & contaminated conditions. and promate a clean working environment,

 

1.Nitride rubber seal – or differing seals depending on temperature needs.

2.Special long-life grease: heat & pressure resistant

3.Symmetrical roller & raceway design to prevent edge loading problems.

4.Special chamfer configuration for smooth axial movement.

5.Available in sealed-clean or grease replenishing types, with shields.

 

Sealed spherical roller bearings benefit are characterised by:

 *very high basic dynamic and static load ratings

 *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.

 *Seals design secures seal dislodging & better running.

 *Symmetrical rollers operate under high-load conditions

 *Available in sealed-clean or grease replenishing types, with shields.

 

The seals for these bearings are made of rubber and reinforced with a steel plate. The options available are made of materials resistant to wear and lubricating oil, such as:

 

- nitrile rubber (NBR): suffix ORN

 

- hydrogenated nitrile rubber (HNBR): suffix ORH

 

- fluorinated rubber (FKM): suffix ORF

 

The internal design of a sealed bearing corresponds to that of an open bearing. The external  dimensions are also the same except for bearings based on the 222 and 223 series. These  bearings are slightly wider and carry the series designation LB-22 and LB-23 respectively.Sealed two-row spherical roller bearing have three barrier protection including sealed two-row spherical roller bearing,bearing body filled in 70% to 90% with grease and external labyrlth seal,representing a very efficient solution.
