The GGB-SHB Case Hardened Steel Bearing is designed for lubricated applications, making it suitable for use in industrial machinery such as earth moving equipment, excavators, and farming machinery. It features a plain or grooved sliding layer and is compatible with grease lubrication. The bearing is optimized for low rotation speeds while supporting high specific pressures. Key properties include a maximum static load of 300 N/mm² and a maximum dynamic load of 150 N/mm². It has a tensile strength of 550 N/mm² and can operate at temperatures up to 150°C. The bearing's surface hardness ranges from 58 to 62 HRC, and it has a surface roughness of ,⧠0.8 Oºm. The maximum sliding speed is limited to 0.1 m/s, with a maximum pv factor of 1.5 N/mm² x m/s and a coefficient of friction of 0.2. This bearing is suitable for applications requiring robust performance under specific conditions.
