The 6203RS is a single-row deep groove ball bearing equipped with a rubber seal (RS) on one side, designed for high-speed, low-friction performance in both radial and axial load applications. This bearing is ideal for use in electric motors, appliances, pumps, and a wide range of industrial and automotive machinery where protection against contaminants and consistent lubrication are critical.
Key Features:
Sealed Design: RS (Rubber Seal) on one side provides protection against dust, moisture, and other contaminants, while also helping retain lubrication.
High-Precision Machining: Designed to reduce vibration and friction, extending equipment life and ensuring smooth operation.
Durability: Constructed from high-quality chromium steel (typically SAE 52100), offering excellent wear resistance and strength under repeated stress.
Pre-Lubricated: Comes with high-performance grease, ready for immediate installation without additional lubrication.
Versatile Application: Suited for both radial and limited axial loads in both directions.
Applications:
Electric motors (fans, blowers, compressors)
Pumps (water pumps, vacuum pumps)
Power tools
Automotive alternators and starters
Agricultural machinery
Conveyors and belt-driven equipment
HVAC systems
Advantages:
Reliable operation in dusty, wet, or vibration-prone environments
Low maintenance thanks to effective sealing and pre-lubrication
Long service life even under continuous or high-speed operation
Standard size ensures easy replacement and global availability
