Frequently Asked Questions

What is a slewing bearing?

A slewing bearing (or turntable bearing) is a large-sized bearing that can support axial, radial, and moment loads simultaneously. It enables smooth rotational movement between two structural parts, commonly used in cranes, excavators, and solar trackers.

How do I select the right slewing bearing?

Selection depends on load type (axial, radial, moment), required torque, speed, mounting space, and environmental conditions. Helin provides technical support and selection guides to help you choose the optimal model.

Do you offer custom designs?

Yes, we specialize in OEM and custom slewing bearings. We can modify dimensions, gear type, sealing, preload, and lubrication systems based on your application requirements.

What certifications do you have?

Helin is ISO 9001 certified. Our manufacturing processes follow international quality standards, and we provide material test reports, inspection certificates, and traceability documentation.
