Internal Gear Slewing Bearing

Internal Gear Slewing Bearings are large-diameter rotational bearings featuring an internally machined gear on the inner ring. They are designed to simultaneously support axial loads, radial loads, and overturning moments while providing precise rotational motion.
With a compact structure and protected gear positioning, internal gear slewing bearings are especially suitable for applications with limited external space and higher requirements for safety and transmission stability.

Operating Conditions

• Designed for combined axial, radial, and moment loads

• Suitable for low to medium rotational speeds

• Operates reliably under heavy-load and intermittent rotation conditions

• Applicable for both horizontal and vertical installations

• Can be customized for harsh environments such as dust, moisture, or vibration

Key Advantages

• High load carrying capacity for axial, radial, and overturning loads

• Compact and space-saving design, with the gear protected inside the bearing

• Stable transmission performance and reduced risk of gear damage

• High positioning accuracy for precise rotational control

• Long service life due to optimized raceway and heat treatment processes

• Supports customized designs to meet specific application requirements

Structural Types

• Single Row Four-Point Contact Ball Slewing Bearing (Internal Gear)

• Double Row Ball Slewing Bearing (Internal Gear)

• Three Row Roller Slewing Bearing (Internal Gear)
• Crossed Roller Slewing Bearing (Internal Gear)

Applications

• Construction machinery (excavators, cranes, rotary platforms)

• Wind power equipment (yaw and pitch systems)

• Port and marine machinery

• Metallurgical and mining equipment

• Industrial turntables and automation systems

• Radar systems and large positioning platforms

OEM / Customization
