Spherical roller bearings

Spherical roller bearings

FV spherical roller bearings are manufactured in different constructive internal design versions (e.g. CA, CC, E, MB, MA, E1, etc.). Spherical roller bearings have cylindrical and conical bores. The taper of the conical bore is 1:30 and 1:12. 

Size range: 100mm -1800mm  (Bore diameter)

Applications: Continuous casting machine, Induistrial gearbox, Papermaking machinery, Crushers, Vibrating screens, Ball mill, Mining machinery, Cement mill roller and other industries.

Spherical roller bearings have two rows of rollers with a common sphered raceway in the outer ring. The two inner ring raceways are inclined at an angle to the bearing axis.  The bearings are self-aligning and conse- quently insensitive to errors of alignment of the shaft relative to the housing and to shaft deflection. In addition to radial loads the bearings can accommodate axial loads acting in both directions.

Most FV spherical roller bearings are made to the standard design (1) which is described in the following and which differs slightly depending on size and series. Specially modified variants of the standard bearings are also produced for particular applicaions, e.g. vibrating screens or rolling mills.


Spherical roller bearings

To order, FV also manufactures special designs of spherical roller bearing.These include split spherical roller bearings (2) for difficultly accessible bearing arrange ments and triple ring bearings(3) which are available in three different basic de- signs. Details of the split spherical roller bearings and the triple ring bearings will be found on pages 423 to 429and 685 to691, respectively.

FV spherical roller bearings(except those identified by designation suffix FA) have a large number of long symmetrical rollers of large diameter and, as a consequence, they have very high load carrying capacity. Their internal design differs slightly depending on series and size,and has been continually improved over the years. The special raceway form and optimised raceway surface finish ensure that the bearings,especially those of the E. CC and CAC designs, have a minimum of friction. These bearings have lower oper- ating temperatures, or can be operated at higher speeds, or can support heavier axial loads than conventional spherical roller bearings.

TYPES OF SPHERICAL ROLLER BEARINGS

FV spherical roller bearings are avail- able with cylindrical bore and tapered bore. The tapered bore of bearings of series 240241,248 and 249 has a taper of 1:30 (designation suffix K30) whereas that of all other bearings has a taper of 1:12 (suffix K).


FV supplies adapter and withdrawal sleeves which can be used to mount spherical roller bearings with tapered bore on stepped and/or smooth shafts easily and quickly.


Designs

FV spherical roller bearings are made to one of the designs described in the follow- ing,depending on size and series, see fig 5.

Designs of spherical roller bearings


 CA 

Bearing with symmetrical rollers, retaining flanges on the inner ring and a guide ring centred on the inner ring between the two rows of rollers. The cage is a one-piece, double pronged machined cage of brass.

 CAB

As the CA design but with pierced rollers and a pin-type cage of steel.

 CAC

As the CA design but with raceway geometry and surface finish refinements which enhance roller self-guidance and reduce friction.

 CACM2

As the CAC design with double pronged machined cage of brass.

 CAF 

As the CA design but with a one piece, double pronged machined cage of steel.

 CAFA 

As the CA design but with a one piece, double pronged machined cage of steel centred in the outer ring.

 CAFB 

As the CA design but with a one piece, double pronged machined cage of steel centred on the inner ring.

 CAMA

As the CA design but with the cage centred in the outer ring

 CC 

As the CJ design but with raceway geometry and surface finish re- finements which enhance roller self-guidance and reduce friction.

 CCJA 

Bearing for vibrating machinery

 CJ  Bearing with symmetrical rollers, flangeless inner ring,a non-integral guide ring between the two rows of rollers centred on the inner ring and one pressed steel window-type cage for each roller row.
 E

Bearing with symmetrical rollers, flangeless inner ring, a non-integral guide ring between the two rows of rollers, two pressed steel window-typecagesone per roller row. Annular groove and three lubrication holes in the outer ring.

 ECA  As the CA design but with reinforced roller complement.
 ECAC 

As the CAC design but with reinforced roller complement.

 ECCJ 

As the ECJ design but with raceway geometry and surface finish refinements which enhance roller self-guidance and reduce friction.

 ECJ 

As the CJ design but with reinforced roller complement.

 FA 

Bearing with asymmetrical rollers, two retaining flanges and an integral guide flange on the inner ring.The outer ring centred, one-piece,double pronged machined cage is of steel.
