SFR 1-5 ZZ RICH 2,38x7,938x3,571

SFR1-5ZZ RICH Stainless Steel Flanged Miniature Deep Groove Ball Bearing - 2.38 x 7.938 x 3.571 mm

The SFR1-5ZZ RICH is a high-quality stainless steel flanged miniature deep groove ball bearing, meticulously manufactured by RICH in China. This precision bearing is specifically designed for applications where corrosion resistance, extremely compact size, and reliable performance within confined spaces are paramount. With precise dimensions of 2.38 mm bore, 7.938 mm outer diameter, and 3.571 mm width, it offers an exceptionally small and effective solution.

Being made from stainless steel, this RICH bearing offers superior resistance to rust and various corrosive agents, making it an excellent choice for use in humid environments, medical devices, food processing equipment, and other applications requiring cleanliness and durability against moisture or chemicals. It features a robust steel cage, ensuring optimal ball separation and stable operation, and its rolling elements have a diameter (Dw) of 1.588 mm. It also has a CN (normal) clearance, indicating a standard radial internal clearance that is suitable for most general applications under normal operating conditions. The integrated flange on the outer ring, with a diameter (D1) of 9.119 mm, provides a convenient and precise means of axially locating the bearing in its housing, simplifying assembly and ensuring accurate positioning. For protection, it comes equipped with double-sided metal shields (ZZ), which help prevent the ingress of dust and other contaminants while retaining the lubricant.

Weighing just 0.001 kg, this incredibly lightweight yet durable component from RICH offers consistent and dependable performance in the most miniature assemblies. It is ideally suited for precision instruments, small robotics, dental equipment, and other demanding applications where space is at a premium, precise positioning is critical, and reliable low-friction rotation with corrosion resistance is required.
