Understanding 6206 Z Bearing Fundamentals

The 6206 Z deep groove ball bearing series delivers 12,500N dynamic load capacity through optimized raceway geometry. With single-sided metal shields protecting SAE 52100 chrome steel components, these bearings maintain 98.6% operational efficiency in contaminated environments. The Z suffix indicates continuous operation up to 13,000 RPM, while RZ variants with non-contact seals reduce friction by 18% compared to traditional designs.

FAQS on 6206 z bearing

Q: What is the difference between 6206 Z and 6206 RZ bearings?

A: The 6206 Z has a single metal shield on one side, while the 6206 RZ features a non-contact rubber seal on one side. RZ seals provide better dust and moisture resistance compared to Z shields.

Q: Can bearing 6206 Z be used in high-speed applications?

A: Yes, the 6206 Z bearing is suitable for moderate speeds. However, its metal shield creates more friction than open bearings, so lubrication and temperature should be monitored in high-RPM applications.

Q: What does the ZZ suffix mean in ball bearing 6206 ZZ?

A: The ZZ designation indicates dual metal shields on both sides of the bearing. This provides basic contamination protection while maintaining lower friction compared to sealed bearings.

Q: Is the 6206 RZ bearing waterproof?

A: While the 6206 RZ's rubber seal offers improved moisture resistance compared to Z-shielded versions, it's not fully waterproof. It provides protection against splashes and humidity but shouldn't be submerged.

Q: How do I choose between 6206 Z, RZ, and ZZ bearings?

A: Select Z for basic dust protection, RZ for enhanced sealing in dirty environments, and ZZ for dual-sided shielding. Consider speed, lubrication needs, and environmental factors when choosing.
