7205B Angular Contact Ball Bearing – High Precision, High Speed & Heavy-Duty

The 7205B Angular Contact Ball Bearing is a single-row angular contact ball bearing designed to accommodate both radial loads and axial loads in one direction. Its optimized internal geometry and 40° contact angle provide a good balance between load capacity, rotational speed and operating stability.

The 7205B is manufactured from high-quality chrome bearing steel (GCr15), with precision-ground raceways and rolling elements to ensure smooth rotation and reliable performance. It is widely used in equipment that requires accurate shaft positioning, stable rotation and resistance to combined radial and axial loads.

With its standardized dimensions and wide range of applications, the 7205B is a practical choice for machinery manufacturers, maintenance suppliers, bearing distributors and industrial equipment users.

High Precision
The 7205B is produced with accurately machined raceways and rolling elements to provide consistent dimensional accuracy and smooth rotation. It is suitable for applications where shaft positioning and running accuracy are important.

High-Speed Capability
Its angular contact design allows the bearing to maintain stable performance during high-speed operation. It is suitable for rotating equipment where reduced friction and stable running are required.

Combined Load Capacity
The 7205B can simultaneously support radial loads and axial loads, making it more versatile than standard deep groove ball bearings in many applications.

40° Contact Angle
The 40° contact angle provides relatively strong axial load-carrying capability while maintaining good radial load performance, making the 7205B suitable for combined-load applications.

High-Quality Bearing Steel
GCr15 chrome bearing steel provides good hardness, wear resistance and fatigue strength, helping the bearing achieve a long operating life under suitable working conditions.

Smooth and Low-Vibration Operation
Precision manufacturing helps reduce friction, vibration and running noise, contributing to stable equipment operation.

The 7205B angular contact ball bearing can be used in a wide variety of industrial and mechanical applications, including:

• CNC Machine Tools – Machine tool spindles and precision rotating assemblies.
• Electric Motors – Motor shafts and other rotating components.
• Pumps – Supports shafts under combined radial and axial loading conditions.
• Gearboxes – Used for shaft support and accurate positioning.
• Compressors – Suitable for high-speed rotating components.
• Industrial Machinery – Used in transmission and rotating equipment.
• Automation Equipment – Suitable for precision mechanical systems.
• Textile Machinery – Supports high-speed rotating shafts.
• Robotics Equipment – Used where smooth and accurate shaft rotation is required.

Angular contact ball bearings are commonly used in pairs or multiple-bearing arrangements when the application requires higher axial load capacity, greater rigidity or axial positioning in both directions.

Common arrangements include:

• DB – Back-to-Back Arrangement
• DF – Face-to-Face Arrangement
• DT – Tandem Arrangement

For applications requiring higher precision or rigidity, matched bearing sets can be supplied according to the equipment design.
