Fast shipping

Well packaged to prevent rust during transit. Each bearing was individually wrapped. Great selection of bore diameters in one catalog.

High quality precision

Noticeably less friction compared to standard bearings I used before. The ABEC-7 rating is genuine. Will order again for future projects.

Good value kit

Most sizes fit perfectly in my miniature gearbox project. One size was a bit tight but loosened up after use. Overall good quality for the price.

Solid miniature bearings

Using in small gearbox applications. They handle the RPM well without overheating. Would prefer if stainless steel was more clearly marked in the kit.

Perfect for my drone build

These bearings are incredibly smooth. I used the 3mm and 5mm sizes for my motor mounts and the friction is minimal. High-speed performance is exactly as advertised.

5 FAQ

Q: Can these bearings operate submerged in water?

A: Standard chrome steel bearings are not recommended for submerged use. Please select our Stainless Steel series for water resistance.

Q: Are all the sizes in this catalog metric measurements?

A: Yes, all bore diameters listed (1mm to 10mm) are standard metric measurements.

Q: Is the grease pre-applied or do I need to add lubricant?

A: All bearings come pre-lubricated with high-speed grease and are ready for immediate installation.

Q: Do you offer bulk discounts for industrial orders?

A: Yes, please contact our sales team directly for pricing on quantities over 100 units.

Q: What is the maximum RPM for the 5mm bore size?

A: Max RPM depends on load and lubrication. For light loads, the 5mm bore can handle up to 30,000 RPM safely.
