SKF Single-Row Deep-Groove Ball Bearing, 12mm ID, 24mm OD - W61901-2RS1 Achieve higher levels of energy efficiency and reliability with this deep-groove ball bearing from SKF. It's manufactured from high-grade stainless steel for superior resistance to corrosion and abrasive chemicals. The bearing is capable of withstanding frequent washdowns, making it suitable to use in food processing applications. It's sealed on both ends to prevent grease contamination and incorporates a food-grade lubricant. You can use this unit to accommodate both radial and axial loads in either direction. • Nitrile rubber seals with good resistance to oils for an extended service life
• Produces very little heat in operation to improve overall efficiency and productivity of machinery
• Quieter operation, thanks to low levels of vibration
• Optimised geometry for superior precision and reliability Applications • Pulp and paper mills
• Conveyor belts and assembly lines
• Automotive gearboxes Why are a bearing's rings usually made from hardened steel? A bearing's rings play an important role in dealing with pressure at the rolling contact area. To cope with this fatigue, the rings are made of hardened steel to extend the service life of the bearing. Depending on specific requirements, SKF uses stainless steels or high-temperature steels in the manufacturing of its bearing rings.
