1 Pair 7207AC P4DB Angular Contact Ball Bearings 35mm x 72mm x 17mm,Machine Tool Spindles and Ball Screw Support Bearing，

Angular contact ball bearings have raceways of inner and outer rings, which move relative to each other in the direction of the bearing shaft. This means that these bearings are designed to accommodate combined loads, i.e. both radial and axial loads.

• Made of premium high chromium bearing steel (GCr15), it features high hardness and strong impact resistance, enabling long-term stable operation under heavy loads and high speeds without easy wear or deformation, effectively extending equipment service life.
• With a 25° contact angle, it can withstand both radial and single-direction axial loads simultaneously. The high-rigidity structure is suitable for scenarios requiring high precision and stability, such as machine tool spindles and motors, improving equipment operating efficiency.
• Equipped with nitrile rubber (NBR) seals, it effectively blocks dust, moisture, and debris from entering, preventing grease leakage and greatly reducing maintenance frequency, suitable for complex industrial environments such as dusty or humid conditions.
• 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.
