High-Quality Gearless single-row cross-roller slewing bearing Manufacturer, Factories

A pure bearing ring without gears, with the raceways precisely ground. Composed solely of single rows of 90° cross-aligned cylindrical rollers and precise V-shaped raceways, it bears axial, radial and overturning moments through a purely linear contact structure. It requires external drive, such as direct coupling drive, friction wheel drive or an independent drive system.

Frequently Asked Questions

What are the core design advantages of this product series?
This series delivers three major performance benefits: highest precision (achieved by eliminating gear processing errors and thermal deformation impact), superior rigidity (guaranteed by a continuous, complete structure), and highly stable, vibration-free, and noiseless operation.
How does the complete structure enhance rigidity?
Unlike traditional components that experience local stiffness reduction due to integrated gear parts, this configuration features a continuous, complete structural design that prevents weak points and maintains uniform stiffness.
Why does this series achieve vibration-free and silent operation?
It operates entirely without gear meshing systems. Because there is no mechanical gear meshing interface, the typical noise and vibration associated with gear interaction are completely avoided.
What precision systems are these products typically integrated into?
They are ideally suited for industrial robot joints (specifically at the rear end of RV reducers), high-precision CNC and optical instrument turntables, high-precision radar and measurement bases, and semiconductor wafer transfer platforms.
How can I identify the sizing and configuration options available?
Detailed dimensions, mounting parameters, and gear specifications can be found in our technical characteristics table. Sizing configuration ranges from the base model 110.25.500 to the larger 110.50.4500 series.
