igus has developed the PRT slewing ring bearing to help engineers and designers solve all problems associated with high load rotational applications. With two layers of self-lubricating low-friction sliding polymer pads, in place of those of traditional ball bearings, this cost-effective solution can be used for a variety of applications, including welding plants and transport systems. The bearings feature a robust design and maintenance-free properties, including resistance to chemicals, low moisture absorption and great vibration dampening. In order to help the end user find the right solution for the right application, the supplier offers this product in a range of different models - one option being the traditional design with iglidur sliding elements and rings made of anodized aluminium or stainless steel. An alternative model, which comprises head rings made of iglidur and supporting anodized aluminium or stainless steel rings, fits cost conscious applications that require a lightweight product.
