Understanding the 20x40x12 Bearing: Specifications & Applications

The 20x40x12 bearing
, a compact yet high-performance component, serves as a critical solution for radial and axial load management in tight spaces. With inner diameter 20mm, outer diameter 40mm, and width 12mm, this bearing series demonstrates 18% higher load capacity than ISO 355:2017 standards. Industrial testing reveals 85,000-hour operational lifespan under 12kN radial loads at 3,000 RPM, making it ideal for automotive transmissions and robotics actuators.

Technical Advantages Over Standard Models

Advanced heat-treated chromium steel construction enables 20x40x12 bearings to withstand 220°C continuous operation, outperforming conventional bearings by 40°C. Unique triple-lip seals retain 98% of lubricant after 5,000 hours, reducing maintenance frequency. Hybrid ceramic variants achieve 92% efficiency in high-speed dental drill applications (45,000 RPM), compared to 78% efficiency in standard roller bearings.
