SKF Ball Bearing, Plain-Race, Deep-Groove, 20mm ID, 42mm OD - 6004-2Z/C3GJN This deep-groove ball bearing from SKF offers superior dimensional stability and durability in extreme industrial settings. Its structural integrity is achieved through a unique heat-treatment process, while its highly homogeneous steel composition provides extra strength. As it's sealed, it uses less grease than open-ended alternatives, boosting productivity by extending the time between maintenance intervals. This versatile bearing is a suitable option for supporting both radial and axial loads, and it's capable of achieving high rotational speeds as it generates minimal vibration. • Wide operating temperature range of -30°C to +150°C for compatibility with demanding conditions
• Shielded on both sides to help prevent lubrication from leaking and reduce pollution and wastage
• Low noise, so enhances the quiet operation of machinery
• Long service life to increase the efficiency of your system Applications • Wind energy generation
• Material handling
• Textile and printing industries
• Hoist, cranes and winders What material is this bearing's cage made from? This bearing has a glass-reinforced polyamide cage. This material has a high-speed capability combined with a lower sensitivity to poor lubrication, which boosts the bearing's performance.
