6302‑2RSH/C3 Double Contact Rubber Sealed Deep Groove Ball Bearing 15×42×13mm C3 Clearance High Temp Motor Bearing

The 6302‑2RSH/C3 single row deep groove ball bearing is equipped with double-sided 2RSH low-friction contact rubber seals and C3 enlarged radial clearance. The increased internal clearance compensates thermal expansion under continuous high-speed and high-temperature operation to prevent bearing seizure. Double contact rubber seals effectively block dust, water mist and impurities while locking internal grease, widely used in high-speed small motors, power tools, fans and light-load high-temperature transmission equipment.
