Inch tapered bearing. Timken-type

The bearing is in two separate parts.

Each reference therefore designates the complete bearing containing the two rings.

The inner ring contains the rollers and the cage.

While the outer ring is in one piece.

Products called "inch size" are designated by a reference of the inner ring, called cone, AND by a reference of the outer ring, called cup.

For example: LM11749/LM11710

LM11749 is the inner ring.

LM11710 is the outer ring.
