Thin and Flexible Outer Ring
The outer ring of the 3E809KAT2 bearing is very thin. It is easy to deform in the radial direction. Before installation, it is round. After installation, it becomes oval.
Mainly Bears Alternating Stress
The flexible bearing mainly bears alternating and cyclic stress during operation. It is suitable for high-frequency deformation.
High-Quality Materials
The inner ring, outer ring, and rolling elements are made of high-carbon chromium bearing steel. This ensures high load capacity and good wear resistance. The cage is made of one-piece nylon, which reduces weight and noise.
Excellent Performance in Harmonic Drive
3E809KAT2 bearing is the core part of the harmonic drive gearbox. It uses its elastic deformation to achieve a high reduction ratio and high transmission accuracy.
Compact Structure and Light Weight
The bearing has a thin wall, small size, and light weight. This helps to reduce the overall size of the mechanism and improve system efficiency.
Smooth Transmission and Low Noise
When used with harmonic drive, the flexible bearing runs smoothly and quietly. It is suitable for applications that require high precision and low noise.
