Our igubal® two bolt and four bolt flange bearings (both the spherical ball and its housing) are designed with our high-performance, self-lubricating plastic materials for dry-running operation. They don’t require any external lubricants, which enables the system to be maintenance-free and resistant to dirt and dust. Our two bolt and four bolt flange bearings are also corrosion resistant, lightweight, vibration-damping, and highly rigid and durable. igubal® compensates for misalignment errors as well as edge loads, and comes with either two or four mounting holes. We rigorously test our flange bearings each year inside of our 41,000ft2 test lab in Germany. The data is stored in our online service life calculator, which you can use to calculate how many hours a specific pillow block is expected to last inside your application. It takes just a few minutes. Simply enter your requirements and see your results instantly. Click the button below to try it out today!
