Inch tapered roller bearings originated in the United Kingdom and the United States, and their structure and assembly dimensional accuracy and rotational accuracy are different from metric bearings. Mostly used for imported machinery or industries with special needs.

Structure type:

1.Single row

2. Double row

3. Four columns

The single tapered roller bearing has an outer ring, the inner ring and a group of tapered rollers are enclosed by a cage cage to form an inner ring assembly, and the outer ring can be separated from the inner ring assembly.

The outer ring (or inner ring) of a double row tapered roller bearing is a single piece. The small end faces of the two inner rings (or outer rings) are similar, with a spacer in between. The gap is adjusted by the thickness of the spacer. The thickness of the spacer ring can also be used to adjust the pre-interference of double row tapered roller bearings.

Four-row tapered roller bearings can withstand extreme radial loads and bidirectional axial loads with low limit speeds. It is one of the main roller bearings. This type of bearing has a large radial and axial load capacity, and the radial load capacity is about 3 times that of a single row. It can withstand large bidirectional axial loads and is used in various hot and cold rolling mills. very broad. Mainly used for work rolls of hot rolling mills and cold rolling mills, and rolls of billet rolling mills.

Tapered roller bearings generally use steel stamping cages, and column cages are used when the size is larger.
