The bearings codes designation:

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.

QBCThe 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]
