Large Diameter Bearings

Large diameter bearings are specially designed to support heavy loads and accommodate large shafts or structures. They are essential components in industries such as wind energy, construction, mining, marine, and heavy machinery, where robust performance and durability are critical.

At ZMS, we offer a comprehensive selection of large diameter bearings, including:
• Large slewing Bearings (Slewing Rings): Ideal for applications requiring rotation and support of heavy loads, such as cranes, excavators, and wind turbines.

• Large tapered Roller Bearings: Suitable for handling combined radial and axial loads in demanding environments.

• Large spherical Roller Bearings: Designed for applications with misalignment and heavy load requirements.

• Large deep Groove Ball Bearings: Versatile bearings with high-speed capability and low friction, suitable for a wide range of large diameter applications.

• Large cylindrical Roller Bearings: Engineered for high radial load capacity and suitable for applications requiring precise alignment and smooth operation.

• Customized Solutions: We can provide custom large diameter bearings tailored to your specific needs and technical requirements.

Frequently Asked Question

What is considered a “large diameter bearing”?

While industry definitions vary, a bearing is generally classified as a “large diameter bearing” when its outer diameter (OD) exceeds 400 mm (approx. 16 inches). At ZMS Bearing, we have the advanced machining capabilities to manufacture custom bearings and slewing rings with outer diameters reaching up to 3 meters.

What is the typical lead time for custom large size bearings?

The lead time for large diameter bearings depends heavily on the size, complexity, and raw material availability (such as large forged rings). Typically, manufacturing a custom large bearing takes anywhere from 70days to 90days. We provide precise timelines during the engineering consultation phase to ensure your project stays on schedule.

How do you ensure the quality of such massive bearings?

Failure in large bearings is extremely costly, so quality control is our top priority. We use high-purity forged steel and subject every large bearing to rigorous testing, including Non-Destructive Testing (NDT) such as ultrasonic and magnetic particle inspections, to detect any internal or surface flaws. We also strictly control the heat treatment process to ensure optimal case depth and core toughness.
