Spherical bearings from igus® are made of expertly-engineered polymers that are up to 40% more cost-effective and up to 80% lighter than metal bearings. Our spherical bearings are easy to mount, more economic in comparison to metal bearings, and are maintenance-free with a long service life. Self-lubricating spherical bearings do not require external lubrication, and are resistant to dust, dirt, and corrosion. igubal® spherical bearings remain reliable in operation despite exposure to corrosion, wet and damp environments, UV radiation from the sun, or nuclear radiation. Suitable for temperatures ranging from -30 to +80°C.
