NSK 20TAC47BSUC10PN7B Super Precision Machine Tool Bearing 20TAC47B SUC10PN7B 20 X 47 X 15mm
NSK Ball screw support angular contact thrust ball bearings .Every end-user who uses NSK cnc milling machine bearings
20TAC47BSUC10PN7B all knows it's high-precision bearing,and widely
used in machine tools.This kind of bearings are very durable and
can be used in many ways,such as face to face,back to back and face
to back.Generally,the accuracy class for 20TAC47BSUC10PN7B is
P4/P5.Compare to standard angular contact ball bearings, ball screw
bearings have longer life and better reliability.They are much
smaller but can support heavier load rating,rely on their best
design for among all ball bearings .
Angular Contact Thrust Ball Bearings Types :
Back to Back ( DB Arrangement )
The majority of machine tool applications use this type of
arrangement. The preload is produced by the ‘Gap’ (2 x the step b)
of the inner ring faces being squeezed together by a locknut on the
shaft. This type of arrangement is particularly useful where moment
loads are used but the accuracy of the housing must be high to
reduce misalignment.
Face to Face ( DF Arrangement )
This arrangement is often used for ball screw support bearing
applications. The preload is produced by the ‘Gap’ (2 x the step f)
of the outer ring faces being squeezed together by an end cap in
the housing. This type of arrangement is particularly useful when
good alignment cannot be guaranteed between the housings. This can
be the case for Ball Screw Support Bearings since ball screws can
often be 1 to 5 meters in length.
Tandem ( DT arrangement )
This arrangement needs to be used with another bearing or set of
bearings in the opposing direction in order to produce a preload
(see diagram). Bearings are used in these arrangements when there
is a need for higher stiffness due to higher axial loads on the
spindle.
