Hollow Rotary Cross Roller Table

Hollow Rotary Cross Roller Table is a core component used in the industrial precision field for workpiece rotation and positioning. 

Hollow Rotary Cross Roller Table is a high-performance rotating platform in modern precision equipment that uses cross roller bearings as its core technology. Its name accurately reveals its two core features: the "hollow" structure and the precise transmission mechanism of the "crossed rollers". It is a top-notch solution designed specifically for handling heavy loads, high rigidity, high precision, and complex torque conditions, representing the pinnacle application of basic mechanical transmission technology.

FAQ:

1. What does the rated radial load of a hollow rotating platform mean?
     Rated radial load is the maximum perpendicular force the platform can handle continuously. This force acts on the output table surface. Exceeding this value reduces bearing life or causes permanent damage.

2. What is the typical ratio of rated axial load to radial load?
    For crossed roller bearings, the axial load capacity equals or slightly exceeds the radial capacity. The typical ratio ranges from 1:1 to 2:1 (axial:radial). Manufacturers specify exact values for each model.

3. How many times can the maximum instantaneous load of Hollow Rotary Cross Roller Table reach the rated load?
Maximum instantaneous load reaches 2 to 3 times the rated load for short peaks. This applies only during sudden starts or stops. Do not exceed this limit, or permanent deformation will occur.

4. What is the impact of load eccentricity on the performance of Hollow Rotary Cross Roller Tables?
Load eccentricity creates an overturning moment. This moment adds extra stress on bearings. It reduces effective load capacity and shortens service life. Higher eccentricity causes more wear and lowers positioning accuracy.

5. How to calculate the overturning moment required for a hollow rotating platform?
Multiply the applied force by its eccentric distance from the platform center. For radial force, moment = radial force × height offset. For axial force, moment = axial force × radial offset. Add vector contributions for combined loads. Consult the manufacturer's formula sheet.
