If you are looking for a more economical alternative to metal spherical bearings you can think about using the igus igubal® spherical bearings. These are made of high-performance plastics which igus® engineers have spent decades researching and perfecting, to ensure the right materials are comparable to metal. These polymer bearings are up to 40% more cost-effective and up to 80% lighter than metal bearings. They are easy to mount and more economic in operation. Why? Because they are maintenance-free and have a long service life. The polymer bearings permit low-friction dry operation without lubricant, they are resistant to dust and coarse dirt, corrosion-free in wet and damp environments and can be deployed in a wide range of media. They remain reliable in operation, even when they have been exposed to UV radiation from the sun or nuclear radiation for many years. Suitable for temperatures ranging from -30 to +80°C, and even up to +200°C in the HT version.
