At ZZ, we design and manufacture high-precision non-gear slewing bearings tailored for rotary tables used in:

• Welding positioners
• CNC indexing systems
• Robotic assembly lines
• Inspection turntables
• Industrial automation platforms

These bearings are particularly suitable for situations where the drive mechanism is external, such as with belt, worm gear, or direct motor coupling. As a result, the overall structure becomes more compact and easier to maintain.

Moreover, gearless slewing bearings offer zero backlash, which is critical for precision positioning and repeatable movement. With no gear engagement, the rotation becomes smoother, while vibration and wear are significantly reduced.

Key Benefits

• First, their smooth and silent operation makes them ideal for sensitive environments.
• Second, they are highly customizable, including mounting holes and sealing options.
• Additionally, we offer different internal structures such as ball bearing, cross roller, or three-row roller depending on load requirements.
• Furthermore, the bearings are sealed and pre-lubricated, reducing maintenance needs.

Whether you’re designing a compact rotary table for a medical device or upgrading a large industrial welding platform, ZZ can provide a slewing ring to match your specific needs.

Application Example

For instance, a client from Germany requested a 950mm non-gear slewing ring for a laser welding rotary table. We designed a cross roller structure with a customized bolt pattern, achieving 0.02mm rotational runout — well within their high-precision requirements.
