694 2RS Miniature Ball Bearings 4x11x4
694 2RS Miniature Deep Groove Ball Bearing is a high precision, high quality double sealed miniature ball bearing. This bearing is differentiated from other bearings by the ABEC 3 accuracy standard for which the bearing is manufactured, the class 10 balls used, and the excellent motor quality rating (EMQ).
Class 10 balls in this bearing are typically only used in ABEC 5 or higher class bearings because of their truer roundness and accuracy. The balls within the bearing share the load capacity, so this also increases service life compared to the standard 25 class balls used by other brands.
When it comes to high-speed applications in confined spaces, the 694 2RS Miniature Deep Groove Ball Bearing stands out as a top-tier solution. This specific bearing is meticulously engineered to handle both radial and axial loads with exceptional efficiency. The “2RS” designation means it comes equipped with double rubber seals. These seals are critical for preventing the ingress of dust, moisture, and debris, ensuring that the internal lubrication remains intact over a prolonged lifespan.
The motor quality class means that the bearings must operate at extremely low noise levels with minimal to no vibration. To achieve this, the raceways of the 694 2RS bearings are precision honed with an excellent surface finish.
Common Applications and Maintenance
Due to its compact dimensions and reliable sealing mechanism, 694 2RS Miniature Deep Groove Ball Bearings are widely used in industrial and scientific applications such as medical and industrial cell phones, flow meters, fuel control, gyroscopes, synchronizers, servos, motors, cryocoolers, lung assist devices, and more. Because the double rubber seals keep the premium grease securely inside, this bearing is virtually maintenance-free, saving you both time and replacement costs in the long run.
As a trusted OEM manufacturer, we guarantee that every single bearing undergoes rigorous quality control testing. We check for vibration, noise reduction, and precise dimensional tolerances before shipping. Whether you need standard replacements or customized solutions for specific temperature and load requirements, our team is ready to assist. Partner with us to ensure your machinery operates smoothly and efficiently under any condition.

Single row deep groove ball bearings have a wide range of applications, are simple in design, cannot be separated, are suitable for high speeds, operate robustly and require little maintenance. The deep raceway grooves and the tight fit between the raceway grooves and the balls enable deep groove ball bearings to withstand axial loads as well as radial loads in both directions.
