These airsoft gearbox bearings are made from steel 1.7131 and precisely CNC machined to provide minimal friction and maximum durability. Designed to ensure smooth gear operation, they contribute to increased rate of fire and reduced wear on internal components.

Thanks to chemical nickel plating, the bearings achieve higher smoothness, extreme wear resistance, and excellent corrosion resistance. The special surface treatment gives them a glass-like smooth finish, ensuring optimal operation without excessive lubrication. They do not feature lubrication grooves, which can cause wear on the gear shafts.

Key Features:

✔ High-strength steel 1.7131 – suitable for powerful springs up to M170
