GQZ 71814 Thin Section Single Row Angular Contact Ball Bearing 70×90×13mm Open Type Precision Rolling Bearing

71814 (standard designation 70014) belongs to 718 series thin-wall angular contact ball bearing.

Open structure design, available variants: 71814A (25° contact angle), 71814C (15° contact angle).

It bears combined radial load and one-way axial load. Ultra-slim cross-section greatly reduces radial installation space. Widely used in pairs (DB / DF / DT arrangement) to withstand bidirectional axial force. Perfect for high-precision equipment with strict dimensional restrictions. Common applications include precision machine tool rotary tables, testing equipment, robotic joints and high-speed precision spindles.
