Angular Contact Ball Bearings: Features: The rotational speed is relatively high, 10,000 to 180,000 rpm; the contact angle is divided into 15 degrees and 25 degrees; the rolling elements are divided into steel balls and ceramic balls; there are two types without seal and double-sided seal. It is widely used in high-speed motors, electric spindles, machining center spindles and other spindles with high-speed requirements.
