What is the equivalent of a 6320DDU bearing?

The 6320DDU is a 100×215×47mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6320DDU, NTN 6320LLU, SKF 6320-2RS1, Timken 6320-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6320DDU bearing?

The 6320DDU bearing has a bore diameter of 100mm, outer diameter of 215mm, and width of 47mm. It has a dynamic load rating of 174 kN, static load rating of 125 kN, and weighs 5280g. Maximum speed with grease lubrication is 3,000 rpm.

Can I replace a FAG 6320DDU with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6320DDU (100×215×47mm) can be replaced with the equivalent NSK part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.

Technical Details & Applications

Specification variations and common equipment types.

Internal Clearance

Normal Clearance (CN)

Standard radial internal clearance. Suitable for most applications under normal operating conditions.

TemperatureUp to ~70°C operating temperature

Seal Type

Rubber Sealed (2RS)

Rubber contact seals on both sides. Superior protection from contaminants. Pre-lubricated, maintenance-free.

Avoid forVery high-speed applications (seal friction limits top speed). Environments exceeding 110°C.
