Machine Tool Angular Contact Ball Bearing P4 Precision B71918 For Metal Cutting

Machine tool bearings as the basis component parts for machine tool, its performance directly affects the speed of the machine, turning precision, rigidity, resistance to flutter vibration cutting performance, noise, temperature and thermal deformation etc, thereby affecting the machining parts precision and surface quality. Therefore, high-performance machine tools have to be equipped with high-performance bearings.

Machine tool bearings typically includes:

Deep groove ball bearings,

Angular contact ball bearings,

Cylindrical roller bearings,

Two-way thrust angular contact ball bearings,

Tapered roller bearings,

Thrust bearings in the six structure types.

Our machine tool bearings are appropriate for complex, versatile and high-performing bearing arrangements throughout the tooling process and on tooling components.

Precision for Machine Tool Bearings:

Bearing precision is generally divided into p0, p6, p5, p4 and p2 five grades, for the precision machine tool bearings, the precision grade should be more than p5-class, and for CNC machine tools, machining center high-speed, high precision machine tools spindle bearing, need to choose p4 grade and above---such as ultra-precision bearings

Machine Tool also named spindle bearings:

Characteristics of machine tool spindle Bearings:

1.Support of axial load in one direction only

2.Adjustment against a second bearing is necessary,

3.Extended ball complement compared to deep groove ball bearings,

4.High rigidity and loading capacity

Externally applied loads are transmitted from one ring to the other along a specific contact angle.

The following machine tool bearing types are available

1.High Speed Angular Contact Bearings (Steel & Ceramic Ball)

2.Single Row Roller Bearings (Straight & Tapered Bore)

3.Double Row Roller Bearings

4.Tapered Roller Bearings (Cup & Cone Style)

5.Deep Groove Ball Bearings

6.Double Direction Thrust Bearings

Description & Applicaitons

1) Machine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, as well as low noise and vibration levels are just some of the challenges.

Features:

• superior bearing performance

• extended speed capability

• high degree of running accuracy

• high system rigidity

• low heat generation

• low noise and vibration levels

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.
