The Type 80 Series slewing bearing is a type of bearing commonly used in trailers, cranes, excavators, and other heavy machinery. Slewing bearings are designed to handle axial, radial, and moment loads and are typically used in rotating parts of machinery, such as turntables or rotating platforms. Applications: 1.Heavy machinery like cranes and excavators. 2.Turntables and rotating platforms. 3.Construction equipment. 4.Trailers that require a rotating mechanism.
High Load Capacity: The Type 80 series is designed to handle heavy loads, which makes it suitable for heavy-duty applications like trailers.
Compact Design: This series often has a compact design, making it suitable for applications where space is limited.
Dual Row Ball Bearings: Many slewing bearings in the Type 80 series use dual-row ball bearings, which provide increased stability and load-bearing capacity.
Sealing Options: Various sealing options are available to protect the bearing from dust, debris, and other contaminants, ensuring longevity.
Grease Fittings: Often equipped with grease fittings for easy maintenance and lubrication.
Materials: Made from high-quality steel or other robust materials for durability and resistance to wear and tear.
