SKF 61801-2Z

SKF 61801-2Z Deep Groove Ball Bearing

Description

The SKF 61801-2Z is a single-row deep groove ball bearing known for its versatility and robust performance. It is designed to handle both radial and axial loads in both directions. The 2Z suffix indicates that it has a metal shield on both sides, which protects the bearing from dust and other contaminants while retaining the factory-applied lubricant. This makes it a low-maintenance solution for a wide range of industrial and mechanical applications.

FAQ

What does the ‘2Z’ suffix in 61801-2Z signify?

The ‘2Z’ (or ‘ZZ’) suffix indicates that the bearing is fitted with non-contacting metal shields on both sides. These shields protect the bearing from larger contaminants and help retain the factory-filled grease, making it maintenance-free for its service life.

Is this bearing suitable for high-speed applications?

Yes, the SKF 61801-2Z is a deep groove ball bearing designed for high rotational speeds. The non-contact nature of the 2Z shields generates less friction than contact seals (like 2RS), making it well-suited for high-speed machinery. Always refer to the manufacturer’s datasheet for specific limiting speeds.

Can I use grease to re-lubricate a 2Z shielded bearing?

No, shielded bearings like the 61801-2Z are considered ‘greased for life’ and are not intended to be re-lubricated. The shields are pressed into the outer ring and are not easily removable without causing damage. Attempting to re-grease can introduce contamination and compromise bearing performance.
