E1-14 Bearing 5210-2RS For Bus Air Conditioner Compressor Clutch

The E1-14 5210-2RS double row sealed ball bearing is a key wearable component installed inside the pulley of bus air conditioning compressor electromagnetic clutches. During vehicle operation, the clutch pulley keeps rotating continuously. This bearing bears both radial load and axial load generated by belt tension, supporting stable pulley rotation and reducing mechanical friction loss.

The dual-side 2RS rubber sealing structure forms reliable protection, blocking engine compartment dust, water splash and oil mist from invading the internal rolling body, avoiding grease leakage and premature bearing wear. High-quality bearing steel and precise grinding process guarantee low noise operation under high-speed rotation, effectively prevent abnormal squeaking noise of the air conditioning clutch.
