Nurpol 9mm Bearing Set

The Nuprol 9mm Bearing Set is a high-quality internal gearbox upgrade designed for AEG airsoft rifles using 9mm bearing-compatible gearbox shells. These precision steel ball bearings replace standard bushings to reduce friction between the gears, resulting in smoother operation and improved overall gearbox efficiency.

Manufactured from durable hardened steel, the bearings are built to withstand high-stress loads and extended use, making them suitable for both standard and upgraded AEG builds. By allowing the gears to rotate more freely, this bearing set helps improve rate of fire, reduce motor strain, and enhance battery efficiency while maintaining consistent performance.

Ideal for gearbox rebuilds, maintenance, or performance upgrades, the Nuprol 9mm Bearing Set is a reliable choice for players looking to improve durability and smoothness in high-performance or high-torque setups.
