6304‑2RSH/C3 Double Contact Rubber Sealed Deep Groove Ball Bearing 20×52×15mm C3 Clearance High Speed Motor Bearing

The 6304‑2RSH/C3 single row deep groove ball bearing is fitted with double-sided low-friction 2RSH contact rubber seals and C3 enlarged radial clearance. The expanded internal clearance offsets thermal expansion during long-time high-speed and high-temperature operation to avoid bearing seizure. Double contact rubber seals effectively block dust, water mist and fine impurities while locking internal grease, widely applied in high-speed small motors, power tools, fans and light-load high-temperature transmission equipment.
