S12003XS0 Bearing Product Overview & Core Advantages
The S12003XS0 is a metric ultra-slim four-point contact ball bearing engineered for compact applications requiring high precision and space optimization. Featuring a single-row design with four-point contact geometry, it efficiently handles combined radial and axial loads from any direction in a minimal cross-section. Manufactured entirely from stainless steel and pre-lubricated, it offers excellent corrosion resistance and reliable performance in demanding environments. Its ABEC-1 precision and extremely thin 2.5 mm width make it ideal for applications where size and weight are critical constraints without sacrificing load capacity.

S12003XS0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry enables the bearing to support combined radial and axial loads from any direction with a single bearing row, providing exceptional load-carrying efficiency in minimal space.
Ultra-Thin Section: With only 2.5 mm width and minimal cross-section, this bearing delivers maximum performance in applications where space and weight reduction are critical design parameters.
All-Stainless Steel Construction: Both rings, balls, and cage are manufactured from stainless steel, providing excellent corrosion resistance and durability in harsh environments while maintaining dimensional stability.
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005"), ensuring smooth operation and precise positioning capabilities.
Pre-lubricated Design: Factory-applied lubrication ensures immediate operation and reliable performance across the specified temperature range of -30°C to 110°C.
