Ultra-Thin Precision Bearing Solution
The S07403CS0 Thin Section Ball Bearing sets new standards for space-constrained applications with its revolutionary 2.5mm cross-section. Designed for high-precision instruments and compact mechanisms, this bearing delivers exceptional performance in medical devices, aerospace controls, and miniature robotics.
Aerospace-Grade Chrome Steel Construction
Manufactured from premium chrome steel with special micro-grinding treatment, this bearing achieves surface finishes below 0.05μm Ra. The advanced heat treatment process enhances material durability, providing 30% longer service life than conventional thin-section bearings.
Record-Breaking Slim Profile
Featuring an ultra-compact 74x80x2.5 mm (2.913x3.15x0.098 inch) design with an incredibly light 0.0106 kg (0.03 lbs) weight, this bearing achieves an industry-leading 30:1 diameter-to-width ratio. The optimized geometry maintains radial load capacity up to 1.2kN despite its minimal profile.
Precision Lubrication System
Engineered for both oil and grease lubrication with special low-torque seals. The micro-precision clearance control ensures consistent performance across temperature variations from -40°C to +150°C, making it ideal for extreme environment applications.
