Self lubricating fiber composite material wrapped bearing

GST joint bearing

Introduction: Maintenance free joint bearings are widely used in industrial applications. They provide the possibility of spatial adjustment in various directions. The use of adjustable joint bearings can eliminate premature failure caused by high edge loads in traditional sliding bearings. But when it comes to stability and maintenance free, traditional metal joint bearings, due to the limitations of their process materials and structural characteristics, often experience jamming or even detachment when the inner metal sphere is pressed into the outer ring with a cut, and the self-lubricating material in the middle wears out or is worn out. The self-lubricating joint bearings of Lanli GST provide the best conditions for maintenance free due to their product structure characteristics.
