Product Description

The KA12738HA3 ball bearing is a high-precision ball bearing engineered for critical industrial applications requiring exceptional accuracy and durability. Designed as a premium ball bearing replacement part, it features ±0.002mm radial runout tolerance and supports radial/axial loads up to 850kg. Compatible with standard mounting interfaces, it operates in -40°C to +120°C environments with grease lubrication. Ideal for robotics, CNC machinery, and aerospace systems, its ceramic-coated steel balls minimize friction and wear. The bearing requires no external power, communication interfaces, or integrated electronics, focusing purely on mechanical performance. Key advantages include extended service life, vibration damping, and corrosion resistance, though specialized installation tools are recommended. With an OD of 38mm and precision-ground races, it ensures smooth rotation under high-speed conditions (max 15,000 RPM). Battery-dependent parameters like screen size or detection distance are not applicable to this purely mechanical component.
