Excellent for RC Cars

These bearings are incredibly smooth. I used the 625ZZ for my RC car upgrade and the difference in wheel spin is noticeable. Genuine NSK quality.

Genuine NSK

Verified authentic via the NSK logo engraving. Running them in a small motor setup and there is zero noise at high RPMs.

Good but packaging

Bearings work well and seem authentic. Only giving 4 stars because the packaging was a bit crushed during shipping, though the product was safe.

Solid performance

Using in a miniature conveyor project. They handle the load well. Slightly pricey but worth it for reliability.

5 FAQ

Q: Is the grease suitable for high-temperature environments?

A: The standard grease handles up to 120°C. For higher temperatures, please inquire about our high-heat lubrication options.

Q: What is the maximum RPM for the 626 model?

A: For the 626 miniature bearing, the limiting speed is approximately 30,000 RPM depending on lubrication and load.

Q: Are these bearings genuine NSK imported from Japan?

A: Yes, all our bearings are sourced directly from NSK Japan and come with authenticity verification.

Q: Do you offer discounts for bulk orders over 100 units?

A: Yes, please contact our sales team directly for bulk pricing tiers and corporate account setup.

Q: What is the difference between ZZ and RS seals?

A: ZZ indicates metal shields on both sides, while RS indicates rubber contact seals. RS offers better dust protection but slightly higher friction.
