Heavy Duty High Accuracy Double Back-to-Back 7201AC Angular Contact Ball Bearing

⚙️Product Advantages:

1. This type of bearing adopts a back-to-back (DB) arrangement and is composed of two sets of bearings. Each pair of DB bearings is installed with wide end faces facing each other, and the structure is stable. When the two sets of DB pairs are further combined into a DBB structure, a double support system is formed. In this way, the force points are distributed more widely, and the system rigidity and preload are about twice as high as a single DB combination, which is particularly suitable for working conditions with high load and precision requirements.

2. Enhanced load capacity. Since the load is shared by four rows of bearings, the stress on a single bearing is significantly reduced, and the overall life is also extended.

3. This structure performs particularly well in equipment that requires high rigidity and high loads, such as large industrial machinery, heavy machine tools, etc. They also play a key role in precision machining center spindles that are subject to large axial forces or overturning moments.

⚙️Product Application:

Single-row angular contact ball bearings are widely used and are commonly found in machine tool spindles, high-frequency motors, gas turbines, centrifugal separation equipment, and front wheel systems of small cars. In addition, they are also often used in various types of mechanical equipment such as differential pinion shafts, booster pumps, offshore drilling platforms, food processing machinery, dividing heads, welding equipment, low-noise cooling towers, electrical machinery equipment, spraying systems, machine slot plates, and arc welding machines.

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
