finally found genuine NSK stainless steel bearings instead of generic replacements.Worth paying a little more for original NSK.

We purchased CAT excavator swing bearings and travel motor bearings for several Caterpillar machines working at a mining site in Western Australia. Downtime on excavators is extremely expensive for us, so genuine quality is critical. Machines have been operating for over 500 hours since replacement with no abnormal noise or temperature increase.We will continue ordering.

We use SKF bearings mainly for stone cutting machines. Not a huge order, only 24 pcs this time.I checked several units personally. factory sealed packaging, everything looked correct. Transit to Zagreb took a bit longer than quoted, maybe 3 days extra.

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.
