What are the dimensions of this SKF ball bearing?

This double-row bearing features a 45 mm bore diameter, a 100 mm outer diameter, and a 25 mm width.

What does the C3 radial clearance indicate?

The C3 designation means the internal radial clearance is greater than standard, ideal for thermal expansion or high speeds.

How do you mount a bearing with a tapered bore?

The tapered bore allows straightforward mounting onto shafts using an appropriate adapter sleeve or withdrawal sleeve.

What is the main benefit of a self-aligning ball bearing?

It compensates for shaft deflections and static or dynamic angular misalignments without generating extra friction.

Does this SKF bearing include built-in seals?

No, this is an open bearing without seals and requires external lubrication.

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.
