Specna Arms J-Cage Bearings - 8 mm

The 8 mm Specna Arms J-Cage bearings are the perfect solution when you want to maximize durability and performance. This set includes 2 plain bearings and 4 ball bearings.

Specna Arms J-Cage bearings are specifically designed for powergun gear boxes that use heavier springs, such as the M130 and higher. The plain bearings provide an excellent durability solution for the spur gears, which carry the majority of the torque. They can handle static pressure and strain without damage, making them more reliable in heavy duty applications.

By combining plain bearings with spur gears and ball bearings with sector gears and bevel gears, an optimal balance of durability and speed is achieved. Ball bearings improve speed and reduce friction.
