Inch Non-Standard Tapered Roller Bearing Series

Inch-system non-standard tapered roller bearings refer to a type of tapered roller bearing where the overall dimensions use imperial units (inches), and their specific dimensions, structure, or specifications do not conform to the standard metric bearing series specifications. They typically originate from the British and American systems, and their structure, assembly dimensional accuracy, and rotational accuracy are generally different from metric bearings

.

The core components of this type of bearing are shown in the table below:

Their main characteristics include

:

• Load Capacity: Capable of simultaneously withstanding significant radial loads and axial loads. The larger the contact angle of the outer ring raceway, the greater its ability to withstand axial loads usually is.

• Separability: The bearing's "inner ring + rollers + cage" assembly (cone assembly) can be separated from the outer ring (cup). This facilitates easier installation, adjustment, and maintenance.

• Adjustable Clearance: The radial and axial clearance of the bearing can be adjusted during installation and use, or preload can be applied. This is crucial for optimizing bearing performance and service life.
