| High Light | 6306-2RS1 rubber sealed ball bearing ，deep groove ball bearing C3 clearance ，30x72x19mm high temp motor bearing | ||
The 6306‑2RS1/C3 single row deep groove ball bearing adopts double-sided 2RS1 contact NBR rubber seals and C3 enlarged radial clearance. The expanded internal clearance compensates thermal expansion under long-term high-speed and high-temperature running to prevent bearing locking. Double contact rubber seals effectively isolate dust, water mist and impurities and retain internal grease. Widely used in high-speed medium-large motors, water pumps, blowers and medium-load high-temperature transmission equipment.
