Fast shipping and exact fit
Exactly what I needed for my 3D printer idler pulleys. The 696 size fit perfectly without any modification.

Good value pack
Overall good quality. One felt slightly stiff out of the box but loosened up after a few minutes of use. Rest were perfect.

Perfect for my drone build
These bearings spin incredibly smooth. I used the 685 model for my motor bells and noticed less friction immediately. Great value for the price.

Highly recommended
Quiet operation and seems very durable. I bought the 688 series for my fishing reel and it works like new.
Q: What is the difference between ZZ and 2RS seals?
A: ZZ indicates a metal shield on both sides, while 2RS indicates a rubber contact seal on both sides. 2RS offers better protection against dust and water.
Q: Is the pre-applied grease high temperature resistant?
A: The standard grease handles operating temperatures up to 120°C. For higher temperatures, please inquire about specialized lubrication options.
Q: Do you sell these in bulk quantities?
A: Yes, we offer bulk pricing for orders over 100 units. Please contact our sales team directly for a quote.
Q: Are these suitable for high RPM motors?
A: Yes, these are designed for high-speed applications and can handle up to 30,000 RPM depending on the specific model and load.
Q: Can I return if I ordered the wrong size?
A: Yes, returns are accepted within 30 days provided the bearings are unused and in original packaging.
