Frequently Asked Questions

What are the main dimensions of a 6301 bearing?

The standard dimensions for a 6301 bearing are a 12mm inner diameter, 28mm outer diameter, and 8mm width.

Can I customize the surface finish for my application?

Yes, we offer zinc galvanization, black oxide, and custom corrosion-resistant coatings for specialized industrial environments.

What is the typical lead time for bulk orders?

Bulk orders typically ship within 14-21 days, though we maintain a stable inventory for standard 6301 models to shorten this time.

Which seal type is best for dusty environments?

For dusty areas, we recommend the 2RS (double rubber seal) variant to prevent contaminant ingress and retain lubrication.

How do I maintain my bearings for longer life?

Regular lubrication every 6-12 months and ensuring proper shaft alignment will significantly extend the operational life of your bearings.

Do you support OEM branding and packaging?

Yes, we provide full OEM support including custom logo engraving on the outer ring and specialized branded packaging for distributors.
