FAQ

What does the ‘2Z/SS’ suffix mean?

The ‘2Z’ (or ZZ) indicates that the bearing is fitted with non-contact metal shields on both sides. These shields protect the interior from larger contaminant particles without increasing friction. The ‘SS’ suffix denotes that the bearing is made from Stainless Steel, providing superior corrosion resistance compared to standard chrome steel.

Are these bearings suitable for high-speed applications?

Yes, bearings with ‘2Z’ metal shields have lower friction than those with contact rubber seals (2RS), making them well-suited for high-speed applications. However, the maximum speed also depends on lubrication and operating conditions. The grease inside is typically rated for high speeds but offers less protection against fine dust and moisture than rubber seals.

What is the main advantage of using stainless steel (SS) bearings over standard chrome steel?

The primary advantage of stainless steel bearings is their resistance to rust and corrosion when exposed to moisture and certain chemicals. This makes them essential for applications in food and beverage processing, marine environments, and the medical industry where hygiene and resistance to washdowns are critical.
