What are the dimensions of this SKF ball bearing?

This bearing has a bore diameter of 55 mm, an outside diameter of 100 mm, and a width of 25 mm.

What does the C3 radial clearance mean?

C3 indicates a radial internal clearance greater than normal, which is ideal for thermal expansion or tight interference fits.

What is the purpose of the tapered bore?

The tapered bore allows easy mounting directly onto a tapered shaft or onto a smooth shaft using an adapter sleeve.

What material is the cage made of?

The cage (TN9) is made of glass-fiber reinforced polyamide, ensuring quiet operation and low weight.

Does this bearing have seals?

No, this is an open bearing without seals, designed for lubrication in a protected housing.

Smooth self-aligning operation from Skf

Practical benefits

Dynamic shaft misalignment compensation: The double-row ball design accommodates shaft deflections and angular misalignments to keep your machinery running smoothly without excess friction.
Easy tapered bore mounting: You achieve a secure and precise fit on the shaft using standard adapter sleeves with the tapered internal bore.
Extended C3 internal clearance: The enlarged radial clearance paired with a lightweight polymer cage supports stable high-speed performance and absorbs thermal expansion during operation.

In a nutshell

The right choise for

Keep your machinery running smoothly with the Skf 2211 EKTN9/C3 double-row self-aligning ball bearing, even when facing shaft deflections or angular misalignment. Its two rows of balls accommodate alignment errors dynamically without increasing friction or internal stress. Thanks to the 55 mm tapered bore, you can achieve a firm, accurate fit on smooth or stepped shafts using an adapter sleeve. The enlarged C3 radial internal clearance paired with a lightweight polymer cage ensures reliable operation during thermal expansion and continuous high-speed rotation.

Product description

Self-aligning ball bearings, with a tapered bore, have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. The tapered bore facilitates ease of mounting via adapter sleeves or withdrawal sleeves.
