Product Description

The excavator walking tooth box bearing, also known as the swing bearing or slewing bearing, is a crucial component in the excavator's undercarriage system. It is responsible for supporting the weight of the upper structure (including the boom, arm, and bucket) and allowing it to rotate smoothly.

Design and Construction:

• The walking tooth box bearing is typically a large-sized, single-row ball or roller bearing designed to handle heavy loads and withstand axial, radial, and moment loads.
• It consists of an outer ring, inner ring, rolling elements (balls or rollers), and a cage that holds the rolling elements in place.
• The outer ring is usually fixed to the excavator's frame, while the inner ring is connected to the upper structure.

Function and Features:

• The primary function of the walking tooth box bearing is to support the upper structure's weight and allow it to rotate smoothly.
  
• It facilitates the excavator's slewing motion, enabling it to swing left and right.
• The bearing's design incorporates seals and lubrication channels to prevent contamination and ensure proper lubrication for smooth operation.
  
• It is designed to handle the dynamic loads and harsh operating conditions encountered in excavator applications, such as heavy digging, lifting, and swinging operations.
