Deep Groove Ball Bearings SKF 6011 -2RS1

The SKF 6011-2RS1 deep groove ball bearing, measuring 55x90x18 mm and featuring a ground seal on both sides, offers protection against dirt and moisture.

This single-row deep-groove ball bearing 6011 -2RS1 accommodates radial forces as well as axial loads in both directions. Manufactured from standard 100Cr6 rolling bearing steel in the SKF Explorer design, the bearing complies with the increased tolerance class P6 or ABEC 3. A robust sheet steel cage guides the rolling elements evenly into the deep raceways. With standard radial clearance, the bearing is designed for a wide range of industrial applications with standard fits.

In which applications does the SKF 6011-2RS1 prove its worth?

Rotating shaft assemblies with a shaft diameter of 55 mm, where effective protection against external contaminants is required, constitute the main field of application for this deep-groove ball bearing. Typical applications can be found in general mechanical engineering as well as in industrial drive systems with combined radial and axial loads. The seals, which rub against the bearing on both sides, retain the lubricant inside the bearing and repel solid particles. The rolling bearing reliably operates within a permissible temperature range of -20 to +120 degrees Celsius.

What are the key features of the 2RS1 seal and tolerance class P6?

The suffixes provide information on the bearing’s sealing and running accuracy. The 2RS1 design features integrated, abiding sealing discs on both sides. This design effectively protects the raceways from contamination and reduces lubricant leakage during operation. Tolerance class P6 (or ABEC 3) has tighter dimensional and running tolerances compared with standard tolerance. This promotes high concentricity, reduces vibrations and ensures smooth shaft operation.
