NSK 6306 2RS C3 Deep Groove Ball Bearing 30x72x19 mm

Construction and design

NSK 6306 2RS C3 is a single row deep groove ball bearing designed for industrial applications requiring sealing and increased internal clearance. Its internal geometry ensures efficient handling of radial loads and moderate axial loads in both directions.

The 2RS version features double rubber seals that protect the bearing from dust, moisture and contamination while retaining lubrication. The C3 clearance allows the bearing to operate at higher speeds and temperatures by compensating for thermal expansion.

Manufactured from high quality bearing steel with precision ground raceways, NSK 6306 2RS C3 ensures smooth, quiet and stable operation.

Industrial applications

NSK 6306 2RS C3 deep groove ball bearing is widely used in electric motors, pumps, fans, gear units and industrial machinery operating under continuous load and elevated temperature conditions.

The bearing size 30x72x19 mm makes it suitable for medium duty industrial systems requiring durability, sealing and reliable performance in demanding environments.
