The 7205CD/HC hybrid ceramic angular contact ball bearing adopts steel rings and silicon nitride ceramic rolling balls, featuring 15‑degree CD contact angle open‑type structure. Ceramic balls feature low density, low friction and excellent heat‑dissipation performance, effectively reducing bearing heat generation under high‑speed running conditions.
It is widely used in high‑speed machine tool spindles, high‑frequency motors and precision automation rotary platforms.
