113.25.500 Slewing Bearing

Product Overview

The 113.25.500 Slewing Bearing is a high-performance mechanical component designed for applications requiring simultaneous handling of axial, radial, and moment loads. Featuring a Single Row Crossed Roller structure and an Internal Gear design, this slewing ring offers exceptional rigidity and rotational accuracy in a compact footprint.

As part of the standard 11 series, the 113.25.500 is engineered with a 500mm raceway center diameter, making it a versatile choice for medium-duty industrial machinery, construction equipment, and automation systems.

Technical Specifications

Key Features & Advantages

1. Enhanced Rigidity (Crossed Roller Design): The 1:1 crossed roller arrangement ensures that the bearing can withstand complex tilting moments and multi-directional loads without compromising precision.
2. Space-Efficient Internal Gear: The internal teeth design allows for a more compact integration with drive motors, protecting the gearing mechanism from external debris and reducing the overall footprint of your equipment.
3. High Rotational Accuracy: Precision-ground raceways and high-quality rollers (Gcr15) ensure smooth rotation with minimal clearance or preload options for zero-backlash requirements.
4. Superior Durability: Manufactured from high-strength forged steel (50Mn or 42CrMo) with induction-hardened raceways to maximize service life even under harsh operating conditions.
5. Standardized Mounting: Pre-drilled mounting holes in both inner and outer rings facilitate easy installation and maintenance.

Typical Applications

The 113.25.500 Slewing Ring is widely used in industries requiring high torque and reliable rotation:

• Construction Machinery: Truck cranes, mini-excavators, and piling rigs.
• Industrial Automation: Robotic arms, rotary tables, and heavy-duty positioners.
• Renewable Energy: Solar tracking systems and medium-sized wind turbine yaw mechanisms.
• Material Handling: AGVs (Automated Guided Vehicles) and ship deck cranes.
• Medical Equipment: X-ray and CT scanning gantries.
