As a reseller, we mainly care about packaging and consistency.Secure crating was excellent. Sea shipment quite rough but no damaged cartons inside container. Reliable supplier for long-term cooperation.

We buy small qty every month. Different models. SKF, INA, FAG mixed. Supplier always patient checking stock. Some bearings old production date but still factory sealed and grease condition good.

Received SKF 6208 and 6210 today. Factory sealed, clean original boxes, laser marking same as previous European stock we buy locally. Installed on bakery production motor already. Quiet running.Only issue: UPS delivery rescheduled once. Not seller fault.

Mixed models, small order but urgent requirement. COC was included in the email. Overall, a reliable and stable sourcing channel for NSK bearings.
