The 61905-2RS1 is a thin-section deep groove ball bearing, designed for applications that require lightweight construction, minimal space, and high rolling performance.
Equipped with rubber seals on both sides (2RS1), this bearing is protected against dust, moisture, and other contaminants, ensuring long-lasting lubrication and extended operational life.
Thanks to its reduced width (9 mm), it is ideal for tight-space installations in electronic devices, medical instruments, robotics, and precision mechanics.
