NSK is one of the largest precision bearing manufacturers in the world, serving global enterprises from the automotive, robotics, and precision machining industries. The Evike.com R&D team was able to source quite possibly the best 7mm bearings around for use in Airsoft AEG gearboxes. We put them through their paces, accumulating over 10,000 gearbox cycles with an M150 spring all in the course of 1 trigger-pull; the NSK bearings continued to work flawlessly.
Internally the NSK 7mm bearings are comprised of stainless steel ball bearings, held by precision machined cages, housed nicely in a stainless steel shell with metal shielding to prevent contamination from dust and grime. The integrated lip ensures a secure and solid fit into all 7mm bearing compatible gearbox shells. These bearings are also the perfect thickness providing enough depth for precision shimming.Nominal Size:
