Product Overview: The BK 2020 Closed-End Drawn Cup Needle Roller Bearing
The BK 2020 is a specialized needle roller bearing featuring a closed-end design, with key dimensions of 20mm Bore Diameter, 26mm Outer Diameter, and 20mm Thickness. This component is part of our comprehensive range of Needle Roller Bearings. Its unique drawn cup outer ring is precision-formed from a thin steel sheet, creating a lightweight yet rigid bearing. The closed-end is a key feature, making it perfect for sealing the end of a shaft, preventing the ingress of contaminants and retaining lubricant.
Ideal for applications with limited radial space, the BK 2020 provides high load-carrying capacity and rigidity. It is designed to be press-fitted into the housing, which simplifies assembly and eliminates the need for retaining shoulders or snap rings. As a leading supplier of industrial components, we ensure our BK 2020 bearings meet strict industry standards for reliable and efficient performance in a variety of mechanical applications.
