Selecting Guide
Open Type (No Designation Suffix) - Suitable for high-speed and even very high-speed operation.
Shielded (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris.
Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than metal shield bearings.
