Highly recommend for robotics
Using these in a robotic arm joint. They handle the load well and stay in place thanks to the flange design.

Perfect for my RC project
These bearings fit exactly into the motor housing. Smooth rotation and no play. Great quality for the price.

Good value, slight grease smell
Works well for my miniature gearbox. Had a slight industrial grease smell upon opening but dissipated after use.

Exact fit as described
Measured the bore with calipers and it was spot on 5mm. Flange sits flush. Very satisfied with the precision.

Okay quality for hobby use
They work but feel a bit stiff initially. Needed some run-in time before becoming smooth. Acceptable for non-critical parts.
Q: What is the tolerance on the outer diameter?
A: We follow ISO standard tolerances for miniature bearings, typically within 0 to -0.008mm depending on the specific size.
Q: Can I remove the seals to clean and re-lubricate?
A: Yes, the 2RS rubber seals can be carefully removed with a fine needle, but this may void warranty and affect dust protection.
Q: Do you offer these in stainless steel material?
A: Standard stock is Chrome Steel. We may offer stainless steel variants for bulk orders. Please contact support for customization.
Q: What is the maximum RPM for the 3mm bore size?
A: For the 3mm bore, the recommended max speed is approximately 25,000 RPM under light load conditions.
Q: Is there a bulk discount for ordering 100 pieces?
A: Yes, volume discounts apply for orders over 50 units. Please add the quantity to your cart to see the adjusted price.
