Material
The 692ZZ bearing is manufactured using high-quality 52100 chromium steel. This material is characterized by its exceptional hardness after heat treatment, which enhances the bearing's wear resistance significantly. It also has good dimensional stability, ensuring the bearing maintains its precision even under varying temperature conditions.
Features
• High rotational accuracy: The precise machining of its components guarantees smooth operation with minimal deviation.
• Excellent sealing: Equipped with double metal shields (denoted by "ZZ"), it effectively prevents the ingress of dust, debris and moisture, while retaining the lubricant inside.
• Low friction coefficient: The optimized design of the rolling elements and raceways reduces friction, contributing to energy efficiency and prolonged service life.
• Strong load capacity: Despite its small size, it can bear moderate radial and axial loads.
Applications
• Office equipment: Used in small motors of printers, scanners and shredders.
• Consumer electronics: Applied in the rotating parts of digital cameras, camcorders and portable DVD players.
• Automotive accessories: Utilized in small mechanisms like electric side mirrors and seat adjustment motors.
• Precision toys: Integrated into high-speed toy cars, remote-controlled helicopters and mechanical model kits.
