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.


2) Rolling bearings for general industrial applications can only partly fulfill these requirements. Therefore, We manufacture a comprehensive assortment of super-precision bearings. Theses super-precision bearings help original equipment manufacturers and end users to further optimize performance parameters of their equipment and applications.
3) The benefits differ depending on the bearing series and applications but include high speed and load carrying ability, long bearing service life, long maintenance intervals and low energy consumption.
Typical applications for super-precision bearings are:
  • metal cutting and woodworking machinery spindles
  • other machine spindles (e.g. balancing machines)
  • high speed rolling mills
  • printing machinery
  • precision ball screws
  • live centres
  • high speed turbochargers
  • vacuum pumps
  • racing cars
  • boat gyrostabilizers
  • machine components for the semiconductor industry

Features:

  • superior bearing performance
  • extended speed capability
  • high degree of running accuracy
  • high system rigidity
  • low heat generation
  • low noise and vibration levels
