AI Overview
The 6203-2RZ is a high-speed, 17x40x12mm deep groove ball bearing featuring non-contact rubber seals (2RZ) on both sides, making it ideal for electric motors. It minimizes friction and heat, providing low-noise operation suitable for industrial machinery, household appliances, and power tools, often found in brands like SKF and Timken.
Key Characteristics for Electric Motors:
- Sealing Technology: The 2RZ suffix indicates non-contact, rubberized gap seals. These provide superior dust protection while offering lower friction and higher speed limits compared to contact seals (2RS).
- Dimensions: Standardized metric size with a bore (inner diameter),outer diameter, andwidth.
- High-Speed Capability: Designed for high RPMs, reducing vibration and heat buildup in high-speed motor applications.
- Performance: Typically features normal internal clearance (C0/CN) and premium grease lubrication for increased service life.
Common Applications:
- Electric Motors (Industrial and Home)
- Power Tools
- Pumps and Conveyors
- High-speed rotating machinery
This bearing is a versatile, efficient choice where low torque and protection from contaminants are required.
