Product Q&A

Q:What are the main applications for this bearing?

It is widely used in machine tool spindles, high-frequency motors, robot technology, gas turbines, centrifuges, and small-size automobile front wheels.

Q:How should angular contact ball bearings be installed?

They are often used in pairs or groups to withstand axial loads in opposite directions, as radial loads generate axial force on the inner ring.

Q:What lubrication methods are supported?

The bearings support grease, oil-mist, air-oil, oil injection, and direct lubrication depending on the specific series and speed requirements.

Q:Does the manufacturer offer customization?

Yes, OEM and ODM services are available, allowing customization of dimensions and load ratings.

Q:What is the lead time for orders?

The average lead time is one month for both peak season and off-season periods.
