FAQ

Question?
What does the ‘DDUNR* AS2S’ suffix mean on this NSK 6001 bearing?

The suffix provides key details. ‘DD’ indicates contact rubber seals on both sides for protection against contamination. ‘U’ stands for universal matching for paired mounting. ‘NR’ means it has a snap ring groove on the outer ring and includes a snap ring for easy axial location. ‘AS2S’ specifies the type of grease used, which is Alvania S2, a high-quality lithium-based grease suitable for a wide range of operating conditions.

Question?
Can I use a standard 6001-2RS bearing as a direct replacement?

A standard 6001-2RS (or 6001-DDU from NSK) would have the same basic dimensions (12x28x8mm) and sealing. However, this specific model (6001DDUNR) includes a snap ring and groove. If your application requires this snap ring for positioning, a standard 6001-2RS will not work. You must use a bearing with the ‘NR’ designation.

Question?
What are the typical applications for a bearing with these specifications?

A 6001 series bearing is very common and used in numerous applications requiring support for radial and moderate axial loads. Typical uses include small electric motors, power tools, automotive components like alternators, gearboxes, pumps, and conveyor rollers where the snap ring feature simplifies the design and assembly.
