ZZ Slewing Bearing

Slewing Bearing Catalogue PDF Download – Full Specs & Selection Guide

When selecting the right slewing bearing for your application, having access to a clear and detailed product catalogue is essential. Therefore, ZZ provides a comprehensive slewing bearing catalogue PDF download, allowing engineers, purchasers, and technicians to browse product specifications anytime.

Our catalogue includes complete technical data for a wide range of slewing rings, including:

  • Single-row ball slewing bearings
  • Cross roller bearings
  • Three-row roller bearings
  • Gearless (non-gear) slewing rings
  • Internal and external gear types

Moreover, each product page contains dimensional drawings, load charts, gear data, and mounting instructions. As a result, customers can confidently select the correct model for cranes, excavators, solar trackers, wind turbines, or custom rotating platforms.

What’s Inside the ZZ Slewing Bearing Catalogue?

In particular, our PDF catalogue offers:

  • Standard dimensions (ID, OD, bolt hole layout)
  • Load capacity (axial, radial, tilting)
  • Gear module and teeth count
  • Seal types and lubrication guidelines
  • OEM replacement options for popular brands

Additionally, we include a selection guide to help users match the right bearing type to specific equipment or industry use cases.

For example, if you are sourcing a bearing for a 20-ton truck crane, the catalogue will point you directly to models in the 900–1200mm range with external gearing and high moment load resistance.
