Light Series Slewing Bearings
The light series slewing bearing is one of the slewing bearings. The light slewing bearing (thin type) has the same structural form as the standard slewing bearing. The production process is the same as the slewing bearing, and both have quality assurance. However, compared with other slewing bearings, the light series slewing bearing is lighter in weight, flexible in rotation, and more convenient to work with.
Light Series Slewing Bearings
The light series slewing bearing is one of the slewing bearings. The light slewing bearing (thin type) has the same structural form as the standard slewing bearing. The production process is the same as the slewing bearing, and both have quality assurance. However, compared with other slewing bearings, the light series slewing bearing is lighter in weight, flexible in rotation, and more convenient to work. This kind of slewing bearing is often used in food machinery, environmental protection machinery, and other fields.
Light series slewing bearings feature:
1. Provide exceptional moment, thrust, and radial load capacities.
2. Normal clearance, suitable for light to medium-duty arrangements that require expected precision.
3. Easy installation, with mounting holes on both inner and outer rings.
4. Lightweight and thin section.
Applications
Light slewing bearing is widely used; construction machinery is the first application ofslewing bearingis also the most commonly used place, such as earthmoving machinery, excavators, stacker, retractor, graders, rollers, rock drilling machinery, riding machines, etc. Other concrete machinery, lifting machinery, engineering ships, aerial work platforms, etc. In addition to various construction machinery, the application scope of light slewing bearing has been gradually expanded. Similar to port equipment, metallurgy equipment, wind power generation equipment, a drilling platform, and other equipment platforms have begun using the slewing bearing to replace the original bearing in an extensive range.
