1 Pcs BS2047TN P4DBB Angular Contact Ball Bearings 20mm x 47mm x 15mm P4 Precision DBB Back-to-Back Pair for Industrial Machinery, 2Pcs Ball Screw Support Bearing

• Meets P4 precision grade standards, featuring high rotational accuracy and low radial runout, suitable for scenarios requiring strict precision such as machine tool spindles and servo motors, improving equipment processing accuracy and operational stability.
• Double-sided 2RZ rubber seal design effectively blocks dust, moisture, and debris from entering the bearing, preventing grease leakage and greatly reducing maintenance frequency, suitable for dusty and humid industrial environments.
• Equipped with a nylon cage (TN type), it features lightweight and low-friction properties, stably holding balls under high-speed conditions, reducing operating noise and vibration, and meeting the quiet requirements of high-speed equipment.
• Flexible Adaptability: Supports multiple pairing methods including DB (back-to-back), DF (face-to-face), and DT (tandem), with a compact structure, convenient installation, and space-saving design, suitable for small machinery and space-constrained equipment.
• Wide Application: Compatible with machine tools, high-speed motors, precision instruments, air compressors, and other equipment, balancing rigidity and high-speed performance, offering excellent cost-effectiveness, and meeting the core needs of industrial transmission.
