Versatile Engineering for Modern Industry

As a leader in the bearing and parts manufacturing sector, our deep groove ball bearing uses define the standard for general equipment manufacturing. By integrating high-carbon chromium steel and precision grinding, we ensure maximum radial load capacity.

Our technical advantage lies in the deep-groove geometry, which significantly reduces friction and heat generation. This allows for high-speed rotation while maintaining extreme stability, making them indispensable for electric motors and automotive transmissions.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

What are the primary deep groove ball bearing uses?

They are primarily used for radial loads and moderate axial loads, commonly found in electric motors, gearboxes, and home appliances due to their low friction.

What is the difference between ZZ and 2RS seals?

ZZ denotes metal shields that protect against larger particles, while 2RS refers to rubber seals that provide a tighter, moisture-proof enclosure.

How do you determine the correct precision grade?

P0 is suitable for general machinery, whereas P6 or P5 is required for high-speed applications where runout must be minimized to avoid vibration.

Can hybrid bearings handle higher temperatures?

Yes, ceramic balls in hybrid bearings have a lower coefficient of thermal expansion and lower friction, reducing heat buildup at high speeds.

What is the typical lead time for custom samples?

Our standard lead time for custom precision samples is approximately 7 working days, including quality validation.

How should I store bearings to avoid corrosion?

Keep bearings in their original oil-coated packaging in a dry, temperature-controlled environment to prevent oxidation.
