**TIMKEN® Single Row Angular Contact Ball Bearings (7200, 7300 Series): Precision Performance for Demanding Applications**
TIMKEN® Single Row Angular Contact Ball Bearings (7200 and 7300 series) are engineered to deliver exceptional performance in applications requiring high-speed operation, precise axial load handling, and reliable radial support. Designed with advanced materials and precision manufacturing techniques, these bearings excel in industrial machinery, automotive systems, and precision equipment where durability, efficiency, and accuracy are critical.
### **Technical Features & Design Advantages**
TIMKEN’s 7200 and 7300 series angular contact ball bearings feature a single-row design with a contact angle optimized to handle combined radial and axial loads. Key technical attributes include:
– **Optimized Contact Angle (Typically 15°-40°)** – Enables efficient management of axial and radial loads simultaneously, reducing stress and extending service life.
– **High-Grade Steel Construction** – Manufactured from premium alloy steel for superior hardness, fatigue resistance, and wear protection.
– **Precision-Ground Raceways & Balls** – Ensures smooth operation, reduced friction, and minimal vibration, critical for high-speed applications.
– **Cage Options (Steel, Brass, or Polymer)** – Customizable cages enhance performance in different environments, from high temperatures to corrosive conditions.
– **Sealed & Shielded Variants Available** – Protects against contaminants while retaining lubrication, ideal for harsh industrial or automotive settings.
### **Performance Benefits**
TIMKEN’s angular contact ball bearings provide several key advantages:
– **High-Speed Capability** – Low friction and balanced internal geometry allow for smooth operation at elevated RPMs, making them ideal for machine tool spindles and turbochargers.
– **Enhanced Load Capacity** – The angular contact design distributes loads more effectively than standard deep groove bearings, improving longevity under heavy or dynamic forces.
– **Rigidity & Accuracy** – Precision tolerances ensure consistent performance in applications requiring tight axial positioning, such as robotics and CNC machinery.
– **Reduced Maintenance Needs** – Advanced sealing options and high-quality lubricants extend relubrication intervals, lowering downtime.
### **Typical Applications**
TIMKEN’s 7200 and 7300 series bearings are widely used across industries, including:
– **Industrial Machinery:** Machine tool spindles, pumps, compressors, and gearboxes where high-speed and axial rigidity are essential.
– **Automotive Systems:** Wheel hubs, transmissions, and turbochargers that demand durability under combined loads.
– **Precision Equipment:** Robotics, medical devices, and aerospace components requiring exacting tolerances and smooth motion control.
By combining robust engineering with TIMKEN’s legacy of reliability, these angular contact ball bearings provide a trusted solution for applications where performance and precision cannot be compromised. Whether in extreme industrial environments or high-performance automotive systems, TIMKEN’s 7200 and 7300 series bearings deliver unmatched efficiency and longevity.
