Product Description

The KA12738HA1 ball bearing is a high-precision bearing ball component from the KA series, engineered for demanding industrial applications in robotics, precision machinery, and automotive systems. Designed with ultra-smooth surface finish (Ra ≤ 0.05μm), it operates within a temperature range of -40°C to +120°C, supporting radial loads up to 3.2kN and axial loads of 1.8kN. The chromium steel construction ensures exceptional durability and corrosion resistance, while its 9.525mm diameter and Grade 10 sphericity (≤0.13μm) enable minimal friction in high-speed rotations (max 18,000 RPM). Its tight tolerance (±0.001mm) and optimized heat treatment process make it ideal for precision positioning systems and motion control modules. Key advantages include extended service life and vibration reduction, though specialized lubrication is required for extreme pressure conditions.
