NSK 685 MC3E (618/5) deep groove ball bearing

Product detailed description

NSK 685 MC3E (618/5) is a precision ball bearing made in Japan that belongs to the category of deep groove ball bearings. This bearing is designed with an emphasis on high precision and reliability, which makes it suitable for use in various industrial applications where dimensions and operating conditions are critical.

The bearing has an inner diameter (d) of 5 mm, an outer diameter (D) of 11 mm and a width (B) of 3 mm. These compact dimensions allow it to be integrated into devices with limited space. The bearing is made of high-quality steel, which ensures high wear resistance and long service life even under difficult operating conditions.

NSK 685 MC3E is equipped with a steel cage that provides stable support for the balls and ensures uniform load distribution. The bearing is designed without a seal, which means it is suitable for applications where friction needs to be minimized and rotational speed maximized. However, the absence of a seal requires the bearing to be used in a controlled cleanliness environment or to be regularly maintained.

The bearing has normal to narrow clearance, which means it is optimized for applications where precise control over movement and vibration minimization are required. This feature is particularly important in precision mechanisms such as small electric motors, instruments and equipment, where accuracy and smooth operation are critical.

The overall designation of the 685 MC3E (618/5) bearing provides information about its design features and parameters, with the manufacturer NSK known for its quality and innovation in the field of bearings. This bearing is an ideal choice for applications where compact dimensions, high accuracy and reliability are required.
