Slewing Ring Ball Bearing 011.30.500 with External Gear for Excavator

Product Overview

Our Heavy-Duty Slewing Bearings are precision-engineered components designed to handle massive axial, radial, and tilting moment loads simultaneously, ensuring smooth and reliable rotation. Manufactured from high-strength forged 42CrMo/50Mn alloy steel and treated with advanced carbonitriding or induction hardening, these bearings deliver exceptional wear resistance, durability, and load-bearing capacity.

With multiple structural options—four-point contact ball, double-row ball, and crossed roller designs—our slewing bearings offer high precision, low friction, and compact integration for a wide range of industrial applications. From construction machinery and material handling systems to automation equipment and robotic platforms, they are the ideal solution for high-performance, long-life rotational motion systems.
