FAQ

What does the ‘2Z/SS’ suffix mean for the 619/5 bearing?

The ‘2Z’ (or ‘ZZ’) indicates that the bearing is equipped with non-contact metal shields on both sides, which protect the interior from larger dust particles without increasing friction. The ‘SS’ suffix signifies that the bearing rings and balls are made from Stainless Steel, providing excellent corrosion resistance.

Is this bearing suitable for high-speed applications?

Yes, the 619/5-2Z/SS, being a deep groove ball bearing with metal shields, is well-suited for high-speed applications. The non-contact nature of the metal shields (2Z) generates less friction and heat compared to contact seals (2RS), allowing for higher rotational speeds.

Can I use grease to lubricate this bearing?

This bearing typically comes pre-lubricated with a standard grease suitable for a wide range of applications. Since it is a shielded (2Z) bearing, it is designed to be lubricated for life and does not require re-lubrication. Attempting to add grease may damage the shields.
