Selecting the right slewing bearing depends on several key factors. First, consider the load requirements: axial, radial, and moment loads your application will face. Igus slewing rings suit lighter loads, while FH bearings handle heavy-duty forces.
Next, think about the environment. Will the bearing operate indoors or outdoors? Is corrosion a concern? Polymer-based Igus rings resist corrosion and dirt, ideal for clean or humid environments. FH steel bearings excel in harsh, dirty, or abrasive conditions.
Speed and rotation frequency matter too. Igus rings work well for moderate speeds and intermittent rotation. FH bearings support continuous, high-speed rotation under heavy loads.
Maintenance capabilities play a role. Igus rings require no lubrication or service, perfect for hard-to-reach or maintenance-free setups. FH bearings need periodic lubrication but offer longer lifespan under stress.
Finally, space and weight constraints influence choice. Igus rings are lighter and more compact, great for designs where weight reduction is critical. FH bearings are heavier but provide robust structural support.
Start by defining the application type. For example:
Robotics or medical devices benefit from lightweight, quiet, and maintenance-free Igus slewing rings.
Construction machinery or wind turbines demand FH bearings for their strength and durability.
Assess how often the bearing will rotate and the forces it will endure. If your project involves frequent, heavy rotation or impact loads, FH bearings offer better reliability.
Consider the operating environment. If exposure to chemicals, moisture, or dust is high, Igus rings resist corrosion better. For extreme temperatures or abrasive conditions, FH bearings withstand wear longer.
Also, think about installation and replacement. Igus rings often come ready-to-install and modular, simplifying assembly. FH bearings may require more precise fitting and maintenance access.
Upfront cost is important, but so is total cost of ownership. Igus slewing rings usually cost less initially and save money on maintenance and downtime due to their lubrication-free design.
FH bearings might have higher initial expense and require maintenance, but they typically last longer under heavy loads, reducing replacement frequency.
Weigh these factors against your budget and operational priorities. For low-load, low-maintenance projects, Igus offers excellent value. For heavy-duty, long-term performance, FH bearings provide cost savings over time.
Igus slewing rings have proven their worth in robotics, especially in lightweight, precision-driven arms. For example, a personal garden robot developed by EEVE uses a custom Igus PRT slewing ring. This bearing allows smooth, quiet rotation without needing lubrication, which is vital for outdoor robots exposed to dirt and moisture.
In another case, a robotics manufacturer integrated Igus slewing rings into their assembly robots. The maintenance-free operation reduced downtime significantly, while the lightweight design helped keep the robot's overall mass low. This improved energy efficiency and responsiveness.
Igus slewing rings also shine in medical robotics, where cleanliness and noise reduction are critical. Their FDA-compliant versions ensure safety in sterile environments, while the polymer sliding elements eliminate contamination risks from lubricants.
FH slewing bearings are widely trusted in construction machinery. For instance, a leading crane manufacturer uses FH steel slewing bearings in their cranes' rotating platforms. These bearings endure heavy axial and radial loads while providing precise, smooth slewing, even in harsh outdoor conditions.
Similarly, FH bearings have been installed in excavators that operate in abrasive, dusty environments. Their hardened steel construction and advanced sealing systems protect against contaminants, ensuring long service life despite tough conditions.
Wind turbine manufacturers also rely on FH slewing bearings for yaw and pitch systems. These applications demand high load capacity and durability, both of which FH bearings deliver consistently. Their customizable gearing and sealing options allow seamless integration into complex turbine assemblies.
