NSK Engraving Machine Angular Contact Bearing 7000 - High-Speed Sealed Angular Contact Ball Bearing

Japan NSK Engraving Machine Angular Contact Bearing 7000 - High-Speed Sealed Angular Contact Ball Bearing

Overview:

Japan NSK presents the 7000 series high-speed angular contact ball bearings, specially designed for engraving machines. These bearings feature an angular contact design with sealing for enhanced durability and reliability, handling large one-way axial loads with ease.

Key Features:

1. Advanced Contact Design: Angular contact ball bearings offer radial points of contact on the steel balls inside and outside the circle, enhancing load capacity. Available in various contact angles—15°, 30°, and 40°—denoted as C, A, and B, respectively. A special 25° contact angle version is available, marked as A5, optimized for heavier loads.
2. High-Load Capacity: Engineered to withstand significant one-way axial loads. The greater the contact angle, the higher the load-bearing capacity.
3. Diverse Material Construction: Made from high-quality steel, brass, or engineering plastic, these bearings can be pressed or turned depending on the application. They also come in different forms, such as combined angular contact, double-row angular contact, and four-point contact ball bearings.
4. Wide Industrial Application: Ideal for various machinery, including metallurgical, mining, paper-making, and textile equipment.
