Self-Aligning Bearings from igus®
Reduce Costs by 40% & Weight by 80%

Self-lubricating, corrosion-resistant & maintenance-free plastics for industrial equipment

igubal® self-aligning bearings are designed with our highly-engineered composite plastic materials that consist of base polymers for wear resistance, reinforcing fibers for high forces, and solid lubricants for smooth, maintenance-free operation. They are resistant to dirt, dust and corrosion, making them suitable for use in liquids and dirty environments. They can also withstand shock, impact and edge loads.

igubal® self-aligning bearings are also 80% lighter than steel and much quieter than metal bearings. By switching to plastic, you can reduce your overall bearing costs by 40% without sacrificing quality and calculate the expected service life before the bearing installed inside your machine.
