The U624ZZ is a miniature U-groove guide pulley bearing designed to run along rails, tracks, wires, or guide surfaces. The U-shaped groove helps keep the bearing aligned during rolling motion, making it suitable for compact guide systems and light-duty mechanical applications.
The ZZ shielded design uses metal shields on both sides to help retain lubrication and protect the bearing from dust and light contamination.
