SKF 6203-2RSL Radial Deep Groove Ball Bearing

SKF 6203-2RSL is a single-row radial deep groove ball bearing that provides smooth rotation and compact load-bearing capability for a wide range of rotary applications. The 2RSL suffix indicates rubber seals on both sides, which help retain grease and protect the rolling elements from dust and other contaminants, reducing maintenance needs in exposed or dusty environments. This specific bearing has a bore of 17 mm, an outer diameter of 40 mm, and a width of 12 mm, placing it in a common 17x40x12 size footprint that fits many standard housings and shaft fits. As part of SKF’s deep groove bearing family, the 6200-series design combines simple construction with robust performance, making the 6203-2RSL a reliable sealed option for equipment requiring steady radial support with predictable behavior across a broad temperature range.
