Pillow block bearing is a bearing unit combining rolling bearing and bearing together. Most of the outer spherical bearings are made outer diameter sphere, installation and imported bearing bore together with a spherical structure forms, versatility and interchangeability. Meanwhile, in the design of such bearings also have some-mind, easy to install, the sealing device has a dual structure, it can work in harsh environments. 1) Material: Chrome steel GCr15 2) Seals type: Open or not. 3) Precision: P0 - P6 4) Vibration: Z1 - Z3 5）Clearance: C0 - C5 6) Bearing series: UC UCP UCPA UCF UCFC UCFA UCT UCFL UCFB etc. 7) Application: Mining, metallurgy, agriculture, chemical industry, textile, printing and dyeing, conveying machinery and so on.
