The bearings codes designation:
H7006C2RZHQ1P4DBA High Precision Spindle angular contact ball Bearing 0

 

The bearings matched ways as below :

DB

The load lines in a pair of bearings by back to back assembly are enlarging from the bearing axis. It can bear axial load in two directions and relative larger moment because of larger angular rigidity.

 

DF

The load lines in a pair of bearings by face to face assembly are convergence toward the bearing axis. It can bear axial load in two directions and smaller moment because of smaller angular rigidity.

DT

A pair of bearings by series a ssembly only bear axial load in one direction, but it is able to bear larger axial load related to DB and DF.

TBT

The tri-bearing matching TBT or TFT isobtained by increasing the same type of the bearing based on DB or DF There are higher axial and radial rigidity for TBT and TFT, so larger load can be supported.

QBC

The four bearing matching QBC (or QFC) is obtained by matching double set of DB (or DF) bearings. QBT (or QFT) is formed when three bearings are installed in a same direction and another one back (or face) to them.

PBC

Divide the five bearings into two groups of three and two bearings respectively, in which the bearings are all installed in the same direction, PBC is formed when the groups match each other by back to back and PFC by face to face. If four bearings are installed in the same direction and another one back (or face) to them, then PBT (or PFT) is formed.

   

 

Why choose the high precision angular contact ball bearings?
 
REASONS BENEFIT

REDUCED RUN OUT (P4,P2)

HIGH WORKPIECE ACCURACY

 

HIGH SPEED

SHORTER WORKING TIME

BETTER SURFACE FINISHING

LOW FRICTION

LOW WORKING TEMPERATURE

PRELOAD

HIGH STIFFNESS

 

How to choose the bearings series during the real application?

 

MACHINE BEARING TYPE BEARING SERIES
TURNING HIGH LOAD 70/719/72
MILLING HIGH LOAD 70/719/72
MACHINING CENTER HIGH SPEED H70/H719
HIGH SPEED MILLING HIGH SPEED +CERAMIC BALL H70+CERAMIC BALL
GRINDING HIGH SPEED +CERAMIC BALL H719+CERAMIC BALL
    H718+CERAMIC BALL
     

 

How to choose the lubrication ways?
 
BEARING TYPE SPEED FACTOR LUBRICATION
HIGH LOAD   <1.0 Mndm Grease
  >1.0 Mndm Oil Bath or circulation
HIGH SPEED <1.5 Mndm Grease
  >1.5 Mndm Oil injection or mist or air-oil
HIGH SPEED+CERAMIC BALL <1.8 Mndm Grease
  >1.8 Mndm Air-oil or minimal oil lubrication

 

 

How to calculate the speed factor

 

Speed factor ndm is calculated to compare working conditions of different bearings, regardless their dimensions.

D  = outer diameter (mm) 

d  = bore diameter (mm) 

n  = shaft speed (rpm) 

dm = pitch diameter (mm) 

 

dm = 0.5x(D+d)

ndm = dm x n

 

How to calculate the grease qty?

 

Q0 = 33% free space 

Q = Q0 x K   [cm3]
