SF6803ZZ Bearing Product Overview & Core Advantages
The SF6803ZZ is a metric flanged ball bearing designed for precision applications requiring compact design and reliable performance. As a single row, shielded bearing constructed from stainless steel, it delivers excellent corrosion resistance while handling radial loads efficiently. Its integrated flange provides secure mounting and precise axial location, making it ideal for applications where space constraints and positioning accuracy are critical. The bearing offers a high limiting speed of 21,600 rpm and maintains stable performance across a wide temperature range from -30° to 110°C.
