6208‑2RS1/C3 Double Contact Rubber Sealed Deep Groove Ball Bearing 40×80×18mm C3 Clearance High Temp Motor Bearing
The 6208‑2RS1/C3 single row deep groove ball bearing features double-sided 2RS1 contact NBR rubber seals and C3 enlarged radial clearance. The increased internal clearance offsets thermal expansion under continuous high-speed and high-temperature operation, effectively avoiding bearing seizure. The contact rubber seals block dust, moisture and impurities while locking internal grease, widely applied to high-speed motors, pumps, blowers and medium-load industrial transmission equipment.
