QJ...-N2-MPA

Thanks to its design with a split inner ring game these allow the incorporation of larger and more number of balls,providing a higher load capacity, in less space than a double row thrust bearings.

Cylindrical roller thrust bearingsare insensitive to shock loading and feature much higher load carrying capacity compared to thrust ball bea- rings.They accommodate very high axial loads but no radial forces.They provide a very rigid bearing assembly for highthrust loading with less space requirement.

3 -- DB

Depending on the particular requirements,such pairs may be supplied arranged either in tandem arrangement (suffix DT),in face to face arrange- ment (suffix DF),or in back to back arrangement

2..-CC-W33

The facility of mounting these bearing types using adapter and extraction sleeves enables mounting directly onto drawn or fine turned seats of shaft for applications where high running accuracy is not necessary.

RNA48,RNA49

Needle  roller  bearings  with  machined  rings  are usually of single -row design with the exception of bearings of the series NA69 or RNA69 respec- tively,which  are  produced  in  double  row design from a specific size onwards.

RSTO

Support rollers are usually exposed to minor mi- salignments during operation.To minimize the negative  effects  of  such   misalignments,(e.g. high edge stresses),support rollers are more fre - quently used with sphered outer rings.

KR

However,cam   followers   with   cylindrical(flat) running surfaces are available for certain appli- cations.Instead of an inner ring,cam followers have a solid stud(pin)that is threaded so that the cam follower can be quickly and easily attached to appropriate machine components by means of a hexagonal nut.

4...-B-TVH

These double row bearings can support heavier loads than the single row ones,with superior load capacity and therefore there are appropriate to replace the single row when the load ishigh.

NNU49..-K-M-W33

They are used as non-locating bearings in bearing arrangements of machine tool spindles.Therefo- re,these bearings are normally used in high pre- cision tolerance class,frequently in combination with reduced internal clearance.

7...-B-M

The capacity of single row angular contact ball Bearings for supporting axial loads depends on their contact angle.The wider the angle,the hig-  her the axial load capacity.
