Hybrid Ceramic Angular Contact Ball Bearing

Silicon Nitride Balls Spindle Bearing

High-Speed Angular Contact Bearing 30×62×16mm

Product Description

1. Product Overview

The 7206CD/HC hybrid ceramic angular contact ball bearing adopts GCr15 steel inner‑outer rings and silicon nitride ceramic rolling balls, with 15‑degree CD contact angle and open‑type construction. Ceramic balls feature low density, small friction coefficient, effectively lower centrifugal force and heat buildup under high‑speed running conditions.

It is widely applied in high‑speed machine tool spindles, high‑frequency motors and precision automation rotary platforms.
