Customized Joint Bearings

key performance parametersFour core parameters need to be paid attention to when selecting the model, which directly determines the suitability and reliability of the bearing:- **Carrying capacity**: The radial basic dynamic load rating (Cr) measures the fatigue resistance, and the Cr value of the steel-steel paired model can reach 280kN (such as GE200ES); the radial basic static load rating (Cor) limits the maximum load at rest or low speed to avoid plastic deformation;- **Allowable speed**: Due to sliding friction, the allowable speed is usually 50-500r/min. The self-lubricating type needs to be controlled within 200r/min due to poor thermal conductivity;- **Angular deviation**: The basic type can reach 3°-5°, and the sealed or self-lubricating type can reach 1°-2°, which compensates for installation errors and component deformations;- **Service life**: Under normal working conditions, the service life of steel-steel paired bearings is 1000-5000 hours. The self-lubricating type can b…
