Angular Contact Ball Bearings: Key Comparisons & Selection Guide- Shanghai Yinin Bearing & Transmission Company

Angular contact ball bearings are essential for high-precision applications, offering superior axial and radial load capacity. This article explores key comparisons, including Angular Contact Ball Bearings 7205, Angular Contact Bearing vs. Deep Groove, and 15° vs. 25° Contact Angles, helping you choose the right bearing for your needs.

1. Angular Contact Ball Bearings 7205: Specifications & Uses

The 7205 series is a popular single-row angular contact bearing with a 25mm bore, 52mm OD, and 15mm width. Key features:

Load Capacity: Higher axial load support than standard deep groove bearings.
Speed Rating: Up to 12,000 RPM (grease-lubricated).
Applications: CNC spindles, pumps, and gearboxes.

2. Angular Contact Bearing vs. Deep Groove: Key Differences

Feature	Angular Contact Bearing	Deep Groove Bearing
Axial Load	High (one direction)	Moderate
Radial Load	High	High
Speed	Higher RPM capability	Lower RPM limit
Best For	Precision machinery	General-purpose use

Choose angular contact bearings for high-precision, high-speed applications, while deep groove bearings suit general radial loads.

3. 15° vs. 25° Contact Angle: Which is Better?

The contact angle affects load distribution and speed:

Angle	Axial Load Capacity	Radial Load Capacity	Speed Performance
15°	Lower	Higher	Higher RPM
25°	Higher	Slightly Lower	Moderate RPM

15°: Ideal for high-speed applications (e.g., machine tools).
25°: Better for heavy axial loads (e.g., industrial gearboxes).

Selecting the right angular contact bearing depends on load, speed, and application. The 7205 series offers balanced performance, while 15° vs. 25° angles optimize for speed or axial load. Compare with deep groove bearings when radial loads dominate.
