Machine tool spindles typically use precision bearings that can handle high speeds, high accuracy, and withstand both radial and axial loads. The specific types of bearings commonly used in machine tool spindles include:

01

Deep Groove Ball Bearings

These bearings are primarily used to withstand radial loads. They are pre-assembled with a fixed clearance and cannot be adjusted, making them suitable for applications that do not require high precision or preload, such as ordinary drilling spindle.

02

Angular Contact Ball Bearings

These bearings can withstand both radial and axial loads. They need to be installed in pairs and can improve the spindle stiffness through preload. Angular contact ball bearings come in various contact angles, such as 15°, 25°, 40°, each with specific application scenarios.

03

Double Direction Thrust Angular Contact Ball Bearings

These bearings typically have a contact angle of 60° and are suitable for applications that require bidirectional axial loads. They are often used in combination with double row cylindrical roller bearings for lathe, grinder, drill, milling machine, and boring machine spindles.

04

Double Row Cylindrical Roller Bearings

These bearings can withstand large radial loads and allow for high speeds. They are commonly used in high-speed rotating machine tool spindles.

05

Tapered Roller Bearings

Tapered roller bearings also have high speed and load-carrying capabilities, being able to withstand both radial and axial loads. Double row tapered roller bearings can handle bidirectional axial loads as well.

Each of these bearing types has its own characteristics. Depending on the specific requirements and performance needs of the machine tool, the appropriate bearing type can be chosen for use.
