GQZ 7030ACM Single Row Angular Contact Ball Bearing 150×225×35mm 25° Contact Angle Open Type Brass Cage

7030ACM is standard single row open-type angular contact ball bearing.

• AC: 25° contact angle, balanced radial and axial load capacity
• M: Machined solid brass cage, stable guiding under heavy load and continuous rotation

Open structure supports grease or circulating oil lubrication. Single bearing withstands combined radial load and one-way axial load. It can be combined as DB back-to-back, DF face-to-face or DT tandem matched sets to bear bidirectional axial thrust. Suitable for medium-high speed, heavy alternating axial load working scenarios. Widely used for large machine tool spindles, heavy-duty ball screw supports, industrial gearboxes, compressors and large automation precision transmission equipment.
