The SMR128-2RS RICH is a high-quality stainless steel miniature deep groove ball bearing, meticulously manufactured by RICH in China. This precision bearing is specifically designed for applications where corrosion resistance, compact size, and reliable performance within confined spaces are paramount. With precise dimensions of 8 mm bore, 12 mm outer diameter, and 3.5 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, guided by the rolling elements, ensuring optimal ball separation and stable operation, and its rolling elements have a diameter (Dw) of 1.2 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. For robust protection, it comes equipped with double-sided rubber seals (2RS), effectively shielding the internal components from dust, dirt, and moisture, while retaining lubrication. This durable sealing significantly contributes to the bearing's extended service life and reduced maintenance needs.
Weighing just 0.001 kg, this extremely lightweight yet durable component from RICH offers consistent and dependable performance in miniature assemblies. It is ideally suited for precision instruments, small electric motors, and other demanding applications where space is at a premium and reliable low-friction rotation with corrosion resistance is critical.
