Slewing Bearing

Used for the safe and precise movement of heavy loads, the slewing bearingis one of the indispensable parts of industrial systems. With its high load capacity, low friction coefficient and long service life, it increases the efficiency of slewing platforms.

Used in many industries from cranes to construction machinery and from wind turbines to the defense industry, these bearings directly affect machine performance.

Types of Slewing Bearings

Slewing bearings come in various types to suit different loads and operating conditions. The most common types are:

• Four-Point Contact Ball Bearings: Can carry axial and radial loads simultaneously and have a wide range of applications thanks to their compact design.
• Cylindrical Roller Slewing Bearings: Preferred in heavy industrial machinery for their high load capacity.
• Crossed Roller Bearings: Resistant to both radial and moment loads; used in applications requiring high precision.
• Thin Section Slewing Bearings: Save space and work efficiently, especially in confined areas.
