Silent operation
I replaced metal bushings with these and the noise reduction is significant. Great for home automation setups where noise matters.

Good quality, tight fit
The build quality is excellent. It was a bit tight on the shaft initially but loosened up after a few cycles. Works as expected.

Durable and reliable
Been using these for 3 months in a high-cycle application. No signs of wear yet. Highly recommend for plastic bearing needs.

Perfect for my CNC project
These bearings fit perfectly on the 20mm shaft. The motion is incredibly smooth without any additional lubrication. Very happy with the purchase.

Arrived with minor scuff
The bearing works fine mechanically, but one unit had a small scuff on the outer diameter. Doesn't affect performance but worth noting.

Q: Can I press these into an aluminum housing?
A: Yes, they can be pressed into aluminum housings. Please ensure the housing tolerance is H7 to avoid deformation.
Q: What shaft tolerance is recommended for installation?
A: We recommend a shaft tolerance of h9 for optimal fit and performance with this inner diameter.
Q: What is the warranty period for this item?
A: This product comes with a 1-year manufacturer warranty against defects in material and workmanship.
