Product Overview
  • 7205ADB is a factory pre-matched duplex angular contact ball bearing set combined by two 7205A single row bearings in back-to-back DB layout, with standard overall dimensions 25*52*30mm and 25° contact angle. Unlike single angular contact bearings that only support one-way axial load, this DB paired structure expands the load center distance, greatly improving overall rigidity and anti-overturning performance, capable of bearing stable radial load and bidirectional axial load simultaneously. The open structure design supports external continuous oil lubriion to meet high-speed and heavy-duty working demands, while precisely ground raceways and brass cage ensure low vibration and quiet stable rotation. Each set is strictly inspected for matching clearance and preload consistency, ready for direct installation without secondary pairing, widely adopted in precision transmission equipment requiring high rotary accuracy and bidirectional load capacity.
