The BAR series is a high-speed thrust angular contact ball spindle bearing with a 30 ° contact angle. It features a non separable back-to-back paired structure and is suitable for high-speed, low heat, and high axial precision machine tool spindle transmission scenarios. It is often used in combination with cylindrical roller bearings.
