Overview of Three Row Cylindrical Roller Slewing Bearing

The LTZC Three Row Cylindrical Roller Slewing Bearing is a robust and versatile bearing solution, designed to handle heavy axial loads, radial forces, and tilting moments. This bearing consists of an inner ring, outer ring, three rows of cylindrical rollers, a cage (spacing blocks), and a seal device, making it highly suitable for applications requiring high load capacity and durability. The unique design of this slewing bearing is ideal for equipment with larger diameters and low friction moment requirements.

The three-row design provides distinct raceways for the axial, radial, and tilting moment forces, allowing the bearing to handle multiple loads simultaneously. It is primarily used in industries where high load capacity is crucial, such as in large-scale construction and heavy-duty machinery.

Features of Three Row Cylindrical Roller Slewing Bearing

Three-Row Design: Separate upper, lower, and radial raceways for better load distribution and stability.
High Load Capacity: Capable of handling large axial and radial loads, as well as tilting moments.
Heavy-Duty Applications: Ideal for machinery with large diameters, including bucket-wheel excavators, wheeled cranes, and marine cranes.
Versatile Gear Options: Available with no gear, internal gear, or external gear configurations to suit different operational needs.
Durable Construction: Made from high-strength materials like 42CrMo, 50Mn, and GCr15, ensuring longevity and performance under demanding conditions.
Customizable Features: Options for lubricant holes, fastening holes, and tooth width adjustments allow for tailored solutions.

This combination of robust design and high load-bearing capacity makes the Three Row Cylindrical Roller Slewing Bearing perfect for demanding industries.
