What are the dimensions of this SKF ball bearing?

This ball bearing has an inside diameter of 50 mm, an outside diameter of 90 mm, and a width of 23 mm.

What does the tapered bore indicate?

The tapered bore (denoted by K) allows for easy mounting onto a shaft using an adapter or withdrawal sleeve.

What protection do the 2RS1 seals provide?

The contact rubber seals on both sides retain lubricant inside the bearing while keeping out dirt and moisture.

What does the C3 radial internal clearance mean?

C3 indicates a radial internal clearance greater than normal, suitable for higher temperatures or tight interference fits.

What material is the cage made from?

The TN9 designation indicates a cage made from glass-fibre reinforced polyamide (plastic).

Smooth rotation through shaft misalignments

Practical benefits

Automatic alignment defect compensation: The double-row spherical outer raceway effortlessly absorbs static and dynamic angular misalignments during demanding operations.
Reliable protection against contaminants: Double-sided rubber contact seals retain internal lubricant while keeping dust and moisture out of raceways.
Simple and secure mounting: The Skf 2210 E-2RS1KTN9/C3 tapered bore enables quick and solid installation using adapter or withdrawal sleeves.

In a nutshell

The right choise for

With the Skf 2210 E-2RS1KTN9/C3, you ensure smooth and reliable operation for your rotating equipment, even under shaft deflection or alignment errors. This double-row self-aligning ball bearing easily accommodates angular misalignments without adding extra friction. Its dual 2RS1 rubber contact seals keep internal lubricant firmly in place while blocking out dust and moisture. The tapered bore makes mounting onto shafts fast and secure using an adapter sleeve. In addition, the increased C3 radial clearance prevents internal bearing preloading caused by thermal expansion or higher speeds, keeping your industrial machinery running without unnecessary downtime.

Product description

Self-aligning ball bearings, with a tapered bore and seals on both sides, 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. The tapered bore facilitates ease of mounting via adapter/withdrawal sleeves. The integral sealing can prolong bearing service life by keeping lubricant in the bearings and contaminants out.

Ease of mounting via adapter/withdrawal sleeves
Accommodate static and dynamic misalignment
Excellent high-speed and light load performance
Low friction
Integral sealing results in reduced maintenance requirements and prolonged bearing service life
