CNC lathes often contain multiple bearings, and the construction of these bearings will vary depending on the specific application of the CNC lathe. The following are some common CNC lathe bearing structural forms:

1.Rolling bearings:

Tapered roller bearings: This type of bearing is suitable for bearing radial and axial loads, and is usually used for spindles and other parts that bear larger loads.

Spherical roller bearings: With self-adjusting function, they are suitable for situations where large deflections or axial loads are tolerated on CNC lathes.

Angular contact ball bearings: Mainly used to support the lateral or longitudinal load of the bearing, suitable for the spindle of CNC lathes.

2. Sliding bearings:

Linear sliding bearings: Used to support CNC lathe worktables, tool holders and other components that require linear motion. Mainly includes sliders and guide rails.

Rotary sliding bearings: Used to support rotating parts of CNC lathes, such as rotary tables, etc. Common ones include sliding bearings, cylindrical roller bearings, etc.

3. Deep groove ball bearings:

It is suitable for parts with low to medium load and high-speed rotation, such as motors and transmission devices on CNC lathes.

4. Combined bearings:

Angular Contact Ball Bearing Combinations: Two or more angular contact ball bearings are combined together to support larger radial and axial loads.

Needle roller bearing combination: Multiple needle roller bearings are combined together, suitable for high load and limited space situations.

5. Ceramic bearings:

Bearings made of ceramic materials have excellent wear resistance, corrosion resistance and high temperature properties, and are suitable for some special working conditions.

6. High speed bearings:

In response to the needs of high-speed rotating parts of CNC lathes, some special high-speed bearings are designed to ensure stability and durability at high speeds.

Different CNC lathe manufacturers and models may use different types of bearings, and the specific bearing structure depends on the design and application requirements of the lathe. When maintaining and replacing bearings, it is recommended to refer to the technical manual of the CNC lathe or consult the manufacturer to ensure the correct bearing is selected.
