MR126 2rs Bearing Product Overview & Core Advantages
The MR126 2RS is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Featuring integral rubber seals (2RS) on both sides, it provides excellent protection against contaminants while retaining lubrication. This bearing excels in applications requiring radial load capacity and moderate speeds, with its chrome steel construction ensuring durability and consistent operation. Its compact dimensions (6mm bore × 12mm OD × 4mm width) make it ideal for precision mechanisms where space is limited and reliable rotational accuracy is essential.
