Rotary table bearings, also known as slewing bearings or turntable bearings, are specialized bearings designed to support axial, radial, and moment loads while allowing smooth rotation. These bearings are commonly used in applications where there is a need for a rotating platform or structure, such as in cranes, excavators, turntables, robotics, and other heavy machinery.
Rotary Table Bearings Features
Single Row or Double Row:
Rotary table bearings can be single-row or double-row designs. Single-row bearings are suitable for applications with light to moderate loads, while double-row bearings provide increased load-carrying capacity.
Gear Options:
Many rotary table bearings come with gear teeth on the outer or inner ring, allowing for smooth rotation when coupled with a pinion or gear motor. This design is common in applications where controlled and precise rotation is required.
Internal Gear, External Gear, or Gearless:
Internal gear bearings have gear teeth on the inner ring, external gear bearings have teeth on the outer ring, and gearless bearings lack gear teeth altogether. The choice depends on the specific application requirements.
Sealing and Lubrication:
Rotary table bearings are often designed to be sealed to prevent contaminants from entering and to retain lubrication. Proper sealing and lubrication are crucial for the longevity and performance of the bearing.
Mounting Holes:
Some rotary table bearings come with pre-drilled mounting holes, making it easier to attach the bearing to the surrounding structure. This feature simplifies the installation process.
High Load Capacity:
Rotary table bearings are engineered to handle axial, radial, and moment loads simultaneously. This makes them suitable for applications where heavy loads and moments are present.
