Frequently Asked Questions

What are the main applications for these angular contact ball bearings?

They are primarily designed for machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, and other equipment requiring high-speed rotation and precise load handling.

What is the advantage of using Bearing Steel Gcr15?

GCr15 chrome steel offers excellent wear resistance, high hardness, and great fatigue strength, ensuring a long service life under heavy radial and thrust loads.

How do I choose between grease and oil lubrication?

Grease is ideal for standard high-speed applications (up to 34,000 RPM) with lower maintenance, while oil lubrication allows for even higher speeds (up to 53,000 RPM) and better heat dissipation.

Do you support different precision ratings?

Yes, we provide various precision levels including ABEC-1, ABEC-3, ABEC-5, ABEC-7, and ABEC-9 to meet different accuracy requirements for industrial machinery.

What seal types are available for these bearings?

We offer multiple options including Open (no seals), Z (single metal shield), ZZ (double metal shields), RS (single rubber seal), and 2RS (double rubber seals) to protect against dust and contaminants.

Can these bearings handle combined loads?

Yes, angular contact ball bearings are specifically designed to support combined radial and axial (thrust) loads simultaneously.
