FAQ

Question? What does the ‘2Z’ suffix mean on the 61701-2Z bearing?

Answer

The ‘2Z’ (or ‘ZZ’) suffix indicates that the bearing is fitted with non-contacting metal shields on both sides. These shields protect the bearing’s interior from larger contaminants without adding rotational friction, making it suitable for high-speed applications.

Question? Is the AKN 61701-2Z pre-lubricated?

Answer

Yes, like most shielded ball bearings of this type, it comes pre-filled with a specific amount and type of grease from the factory. The shields help retain this lubricant for the life of the bearing, meaning it does not require additional lubrication.

Question? What are the primary applications for a thin-section bearing like the 61701 series?

Answer

Thin-section bearings, such as the 61701-2Z, are ideal for applications where space is limited, but a relatively large bore diameter is required. They are commonly used in robotics, medical equipment, semiconductor manufacturing machinery, and other compact, high-precision devices.
