What are the dimensions of this SKF bearing?

This self-aligning ball bearing has an inner bore diameter of 50 mm, an outer diameter of 110 mm, and a width of 40 mm.

What does the K designation stand for?

The letter K indicates a tapered bore with a 1:12 taper, designed for mounting on a tapered shaft or with an adapter sleeve.

What does the C3 radial internal clearance mean?

The C3 rating means the bearing has a greater internal radial clearance than standard, accommodating thermal expansion or tight fits.

Does this ball bearing come with seals?

No, this is an open bearing without built-in seals, requiring external lubrication and protection from contaminants.

What is the benefit of a double-row self-aligning bearing?

It accommodates static and dynamic angular misalignment or shaft deflections without creating additional friction.

Reliable rotation under shaft deflection

Practical benefits

Dynamic misalignment compensation: The double-row spherical outer raceway accommodates angular misalignment smoothly, ensuring you prevent edge loading during shaft deflection.
Fast and secure mounting: With its tapered bore, the 2310 K/C3 mounts easily onto adapter or withdrawal sleeves on plain or stepped shafts.
Increased internal thermal clearance: The internal C3 clearance prevents binding when operational heat expands components, giving you smooth running at high speeds.

In a nutshell

The right choise for

Keep your industrial drive systems running smoothly with the Skf 2310 K/C3 self-aligning ball bearing, even under shaft deflection or misalignment. Its double-row design and sphered outer raceway easily accommodate angular misalignments without increasing friction. Featuring a tapered bore, this 50X110X40 mm open bearing mounts securely and simply onto smooth or stepped shafts using an adapter sleeve. The increased C3 radial internal clearance prevents binding during thermal expansion, ensuring reliable, high-speed performance in demanding machinery.

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.
