Good product, slow ship
Bearings are authentic and work perfectly. Only giving 4 stars because shipping took a day longer than expected. Product itself is flawless.

RC Motor Upgrade
Bought the 608 size for my RC motor. Noticed an immediate difference in RPM and heat management. Genuine NSK quality is worth the price.

Replaced old bearings in my electric fan motor. Still running strong after 6 months of continuous use. Very durable.

Authentic NSK
Checked the laser engraving and packaging. These are definitely genuine Japanese imports. Fitment was perfect for my 6004 application.
