  • We’ve been sourcing deep groove ball bearings from this supplier for over a year now, and the quality has been consistent across all batches. We use them in our electric motor assemblies, where long lifespan and low noise are critical. The bearings are well-sealed, operate smoothly even under heavy load, and meet ISO standards. Delivery times have also been reliable, which is important for our production schedule. Overall, very satisfied and we intend to scale up our orders this quarter.

  • Ordered FAG bearings for a heavy-duty application. Smooth operation, zero issues so far. You can tell these are not low-grade copies, but the real deal. Will buy again soon.
