6903 2RS Rubber Sealed Bearing
6903 2RS is a ball bearing with an inner diameter of 17mm, an outer diameter of 30mm and a width of 7mm. Commonly used in a variety of industrial and mechanical applications. It is a deep groove ball bearing with a single row of balls and deep grooves on both the inner and outer rings to bear axial and radial loads.
The “2RS” in the name means the bearing has two rubber seals that help keep contaminants out and keep it lubricated. This makes the bearing suitable for harsh environments where dirt, dust and other contaminants are present.
● Durable and corrosion resistant
● Can withstand radial and axial loads
● Suitable for medium to high load applications.
● High-speed capability
● Wide temperature range of operation makes it suitable for a wide range of environments.

The 6903 2RS is typically constructed of chrome steel for durability and corrosion resistance. The bearing can accommodate radial and axial loads and is therefore suitable for medium to high load applications. It can run at relatively high speeds, usually up to around 18,000 revolutions per minute (RPM).
Proper lubrication is critical to bearing life and performance. It is recommended to lubricate the bearings with high quality grease or oil. 6903 2RS ball bearings are widely used in industrial and mechanical applications thanks to their versatility, durability and ability to handle axial and radial loads.
