The 16004-2RS is a premium-grade single row deep groove ball bearing engineered for applications where space is premium and weight reduction is critical. Featuring a 20 mm inner diameter, a compact 42 mm outer diameter, and a slim 8 mm width, this thin-section bearing delivers exceptional performance without sacrificing structural integrity. Its optimized deep-groove raceway geometry allows it to manage high radial loads alongside moderate axial forces in either direction. Fitted with dual contact rubber seals (2RS), the bearing ensures excellent exclusion of environmental contaminants while locking in high-performance factory grease—making it the ultimate choice for compact electric motors, automated robotics, and precision instruments.
