xiros® thrust bearings are made of xirodur®® high-performance polymers which lead to a significant weight reduction when compared to metal ball bearings. Their vibration-dampening capability is up to 250 times that of metallic bearings and provides for smooth-running and excellent wear rates. As neither external lubrication nor general maintenance is required, these thrust bearings work well in a variety of applications, whether medical cleanroom equipment, dirty and dusty packaging environments or even FDA compliant food contact.
xiros® thrust bearings consist of an outer and inner race as well as the cage which are all made of xirodur®® high performance polymers, designed and created by igus®. The plastic material is self-lubricating due to microscopic lubricating particles embedded inside the polymers. The rolling elements, or balls, are made of stainless steel or glass depending on the application they are intended for. Further properties include:
