How to select rotary table bearings

Rotary table bearings are essential components that allow for smooth and precise rotational movement in various industrial applications.Selecting the right rotary table bearings is crucial for ensuring optimal performance and longevity of your equipment.

Rotary table bearing selection

1. Load and Speed

Load type: Determine the type of load the bearing will experience (axial, radial, or combined).

Load magnitude: Calculate the expected load on the bearing in both static and dynamic conditions.

Rotational speed: Consider the desired rotational speed of the rotary table.

2. Bearing Type

Several types of bearings are suitable for rotary tables, each with its own advantages and limitations:

Ball bearings: Offer high precision and low friction but have limited load capacity.

Roller bearings: Can handle higher loads than ball bearings but may have lower precision.

Crossed roller bearings: Combine the high load capacity of roller bearings with the high precision of ball bearings.

Tapered roller bearings: Suitable for applications with high axial and radial loads.

Thrust bearings: Primarily handle axial loads.

3. Size and Dimensions

Inner and outer diameter: Choose a bearing with appropriate dimensions to fit your rotary table design.

Bearing width: Consider the space available for the bearing and its load capacity requirements.
