GQZ 7206CD/HC Hybrid Ceramic Single Row Angular Contact Ball Bearing 30×62×16mm 15° Contact Angle Open Type
7206CD/HC follows standard super precision angular contact bearing specifiion.
- CD: 15° contact angle, high-capacity D internal geometry, universal design for DB/DF/DT matched assembly
- HC: Hybrid construction, GCr15 steel inner & outer rings + silicon nitride ceramic rolling elements with electric insulation capability
Open structure supports circulating oil lubriion. It bears combined radial load and one-way axial load. Single unit can be arranged back-to-back (DB), face-to-face (DF) or tandem (DT) to withstand bidirectional axial loads. Ceramic balls reduce centrifugal force at high rotation speed, restrain electric erosion and lower operating temperature. Widely adopted on high-speed CNC spindles, frequency conversion servo motors, ball screw supports and high-precision rotary equipment vulnerable to stray current damage.
