SA Plain Steel Bushings – 8 mm

Specna Arms 8 mm steel bushings for AEG gearbox
They provide solid support for the shafts of gears and are designed for gears with shafts measuring 3 mm in diameter. Unlike ball bearings, bushings have a simple solid construction without balls or other moving parts. During gearbox operation, the gear shaft rotates directly against the smooth sliding surface of the bushing. This makes them a simple design suitable even for mechanically stressed builds. The bushings are made of steel. For proper operation of the sliding contact, we recommend suitably lubricating the contact surface between the shaft and bushing, for example with PTFE grease. Before installation, it is necessary to check both the 8mm diameter of the seats in the gearbox and compatibility with the 3mm shafts of the gears being used. The package contains a total of 6 bushings, providing a pair for each of the three gears in a standard AEG gearbox.
Key features of Specna Arms 8 mm bushings

Solid bushing construction
The bushings contain no balls or other moving parts. The gear shaft rotates directly against the smooth sliding surface of the bushing.

8 mm diameter
The bushings are designed for AEG gearboxes with 8mm seats. Before installation, we recommend checking the diameter of the holes in the specific gearbox shell.

For 3mm gear shafts
The inner diameter of the bushings corresponds to gear shafts with a diameter of 3 mm. When combining parts from different manufacturers, both dimensions must be checked.

Steel construction
The solid steel construction provides a simple gear support suitable even for mechanically stressed AEG gearbox builds.

Complete set of 6
The package contains 6 bushings, providing a complete set for supporting the three gears in a standard AEG gearbox.
