Ultra-Slim Thin Section Bearings - Designs and Variants
Radial Contact Ball Bearings
Radial contact ball bearings are designed to carry primarily radial loads, providing smooth, low-friction performance. These are ideal for applications where axial loads are minimal, and high radial capacity is needed.
Angular Contact Ball Bearings
Angular contact ball bearings support both axial and radial loads, making them suitable for high-speed applications with combined load demands. These bearings are used in machine tools, automotive systems, and more.
Four-Point Contact Ball Bearings
Four-point contact ball bearings are capable of handling axial loads in both directions and offer excellent space-saving solutions. Ideal for use in robotics, rotating platforms, and other precision equipment.
