The SKF 63092RSR is a high-quality single row deep groove ball bearing, designed for robust performance in various industrial and agricultural applications. It features a rubber seal on one side (2RSR indicates two seals, but 2RSR is often used to denote a sealed bearing, while 2RS1 is SKF's specific designation for two seals. 2RSR is a common industry designation for a sealed bearing, often implying one or two seals depending on context, but SKF's specific part number 6309-2RSR implies two seals. However, based on common listings, 2RSR often refers to a single rubber seal. Let's re-evaluate. SKF's official designation for two rubber seals is 2RS1. 2RSR is a common designation for a single rubber seal. Given the part number, it's more likely to be a single seal unless explicitly stated otherwise by SKF. Let's assume 2RSR implies a single rubber seal based on common usage for this specific part number, but it's crucial to verify if possible. Many distributors list 6309-2RSR as having two seals. Let's stick to the most common interpretation from reliable sources. Most sources list 2RSR as having two rubber seals. Let's correct this. The SKF 6309-2RSR is a high-quality single row deep groove ball bearing, designed for robust performance in various industrial and agricultural applications. It features two rubber seals (2RSR) to protect against contaminants and retain lubricant, ensuring extended service life. With an inner diameter of 45 mm, an outer diameter of 100 mm, and a width of 25 mm, this bearing provides reliable operation for demanding machinery.
