What is the equivalent of a 6011-2RSR bearing?

The 6011-2RSR is a 55×90×18mm deep groove ball bearing with verified equivalents across multiple brands: SKF 6011-2RS1, FAG 6011-2RSR, NTN 6011LLU, Timken 6011-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6011-2RSR bearing?

The 6011-2RSR bearing has a bore diameter of 55mm, outer diameter of 90mm, and width of 18mm. It has a dynamic load rating of 29.6 kN, static load rating of 21.2 kN, and weighs 371g. Maximum speed with grease lubrication is 10,000 rpm.

Can I replace a NSK 6011-2RSR with a SKF equivalent?

Yes. NSK and SKF bearings with the same ISO designation are dimensionally interchangeable. The 6011-2RSR (55×90×18mm) can be replaced with the equivalent SKF 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.
