7218BECBMP5 Ceramic Angualr Contact Ball Bearings 90 * 160 * 30mm

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
