FAG Needle Roller Bearings Guide
Product Description
The BK2020 FAG drawn cup needle roller bearing consists of a thin-walled drawn outer cup with a closed end, needle rollers, and a cage, without a separate inner ring. The shaft can serve directly as the inner raceway, which helps minimize radial installation space. The closed-end BK design also encloses the shaft end and helps retain lubricant. With its needle roller line contact, the bearing combines high radial load capacity, compact dimensions, and good rigidity in a very small installation space.
The BK2020 bearing is suitable for automotive, precision machinery, small electric drives, industrial transmissions, power tools, and general mechanical engineering. Its compact radial cross-section is particularly useful for small mechanisms where installation space and weight are limited. Meanwhile, the closed-end construction provides additional protection around the shaft end, making it suitable for compact designs that require radial load capacity, space efficiency, and effective enclosure.
