TORRINGTON B 328 Drawn Cup Needle Roller Bearing | 1.500" Bore | High Capacity, Compact Design
The TORRINGTON B 328 is a heavy-duty, drawn cup needle roller bearing engineered for applications requiring high radial load capacity within extremely restricted radial space. Utilizing a precision-drawn steel outer shell, this bearing assembly requires no axial location components (like snap rings or shoulders) in the housing, reducing complex machining needs and overall installation cost. The full complement of hardened steel rollers ensures maximum dynamic load rating (Cr) for its size, making it the ideal solution for compact industrial gearboxes, automotive transmissions, and hydraulic pumps operating under demanding conditions. Its construction allows for simple press fit directly into the housing bore, providing a rigid, economical, and reliable bearing solution.
Designed for superior performance and long service life, the B 328 bearing excels in rotational speed and durability where conventional ball or roller bearings are too bulky. This unit is commonly lubricated through the shaft or housing, relying on the inherent high efficiency of the needle roller design to minimize friction and heat generation. Choosing the TORRINGTON B 328 ensures you are installing a historically proven component known for its robust performance in applications ranging from construction equipment to specialized machine tools, delivering unparalleled compactness and reliability in a standardized inch-series package.
