Turntable Bearings

1.Product Introduction: Also known as turntable slewing bearings, with 360° flexible slewing, divided into light, medium and heavy load-bearing grades, suitable for various turntable equipment, and the mounting surfaces are precision ground.
2.Structure Type: It has an annular shape (some are split for easy installation), made of thick-wall 50Mn steel, with single or double-row steel balls or rollers, dust-proof seals, and the flatness of the mounting surface is ≤0.1mm/m. Some are equipped with locating pin holes.
3.Size Range: Outer ring diameter: 200 - 5000mm, inner ring diameter: 160 - 4800mm, height: 20 - 180mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Machine tool turntables (vertical lathes), radar turntables, exhibition display equipment (rotating display stands), heavy logistics turntables.
6.Key Inspection Items: Flatness of the turntable, running noise of rolling elements, flatness of the mounting surface.

FAQs

Q: Can you make products larger than φ5000mm?
A: Yes! Our modular design approach allows custom bearing solutions up to φ8000mm.

Q: How do you achieve faster lead times?
A: We use pre-machined modules and agile production lines to cut machining steps by 40%.

Q: Do your bearings work in saltwater environments?
A: Absolutely. Specify our Sealed-for-Life series with fluororubber seals and anti-corrosion coatings.

Q: Can I get IoT-enabled bearings?
A: Yes! Our smart slewing rings come with embedded sensors for real-time load/temperature monitoring.
