What is the equivalent of a 6317-2RSR bearing?

The 6317-2RSR is a 85×180×41mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6317DDU, NTN 6317LLU, SKF 6317-2RS1, Timken 6317-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6317-2RSR bearing?

The 6317-2RSR bearing has a bore diameter of 85mm, outer diameter of 180mm, and width of 41mm. It has a dynamic load rating of 133 kN, static load rating of 90 kN, and weighs 3000g. Maximum speed with grease lubrication is 3,800 rpm.

Can I replace a FAG 6317-2RSR with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6317-2RSR (85×180×41mm) 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.
