Perfect for my drone build
These bearings are incredibly smooth. I used the 3mm bore size for my motor mounts and the performance is noticeable. Genuine NSK quality as expected.

Great variety of sizes
Ordered multiple bore sizes for different prototypes. All arrived well-packaged and protected from rust. Will order again for future projects.

Genuine NSK quality
Verified authentic packaging and engraving. The runout is minimal which is critical for my precision project. Highly recommend this seller.

Good but tight fit
The bearings are high quality, but the 5mm bore was a very tight fit on my shaft. Needed slight polishing. Otherwise, they spin very fast without noise.

High RPM capable
Running these at approximately 20,000 RPM in a spindle application. No heat buildup or vibration after an hour of continuous use. Excellent product.
Q: Can I select the specific bore size during checkout?
A: Yes, please select your required bore size from the variation dropdown menu on the product page before adding to cart.
Q: What is the warranty period for these bearings?
A: We offer a 30-day return policy for defects. Manufacturer warranty applies according to NSK standard terms for industrial components.
Q: Do these come pre-lubricated or do I need to add oil?
A: They come pre-lubricated with standard grease. You can add oil if your specific application requires lower friction, but grease is recommended for longevity.
Q: Are these bearings authentic NSK products?
A: Yes, all our bearings are sourced directly from authorized distributors and are 100% genuine Japan NSK products.
Q: What is the maximum RPM for the 1mm bore size?
A: Maximum RPM depends on load and lubrication, but generally, miniature bearings of this size can handle up to 30,000 RPM under light load conditions.
