Missing one size

The 1.5mm slot was empty in my box. Contacted support and they sent a replacement quickly. Quality is fine otherwise.

Perfect for my drone build

Sizes were accurate and the bearings spin very smoothly. I used the 2mm and 3mm sizes for my motor mounts and noticed less vibration immediately.

Good quality, slight grease excess

Overall great kit. Some of the smaller bearings had a bit too much grease out of the box, but easy to clean. Precision seems good for the price.

Exactly as described

Needed 2mm bearings for a hobby project and this catalog had everything. The labeling on the box makes it easy to find the right size quickly.

Great assortment

Box organization is helpful. I keep this on my workbench for various RC car repairs. The rubber seals hold up well against dust.

5 FAQ

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

A: All bearings come pre-lubricated with low noise grease. You can add oil later if needed for specific high-speed applications.

Q: What is the maximum RPM for the 3mm bearing?

A: Maximum RPM varies by load and lubrication, but generally, these miniature bearings can handle high speeds suitable for RC motors and drones.

Q: Do you ship internationally?

A: Yes, we ship worldwide. Shipping times and costs vary by location and are calculated at checkout.

Q: Can I purchase individual sizes instead of the full catalog?

A: This listing is for the assorted kit only. Please check our other listings for bulk packs of specific sizes.

Q: Are these bearings corrosion resistant?

A: Standard kits are Chrome Steel. We also offer Stainless Steel versions which provide better corrosion resistance for humid environments.
