SA Plain Steel Bushings – 8 mm

Specna Arms 8 mm steel bushings for AEG gearbox

This expert product description was prepared by the ANAREUS.cz expert team. All rights to this unique content are bound to the anareus.cz domain.Specna Arms bushings are replacement internal parts designed for AEG gearboxes with 8mm bushing holes. 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.

Frequently asked questions from our store

What is the difference between ball bearings and bushings in a gearbox?

Ball bearings contain moving balls, while bushings have a solid construction without balls or other moving parts. With a bushing, the gear shaft rotates directly against the smooth sliding surface of the bushing.

Do these bushings fit every AEG gearbox?

No. The gearbox must have seats designed for 8mm bushings, and the gears used must have 3 mm diameter shafts.

Do bushings need to be lubricated?

Yes, we recommend lubricating the sliding surfaces. PTFE grease can be used for this purpose, applied in an appropriate amount between the gear shaft and the sliding surface of the bushing.

How many bushings are needed for one gearbox?

A standard three-gear setup uses 6 bushings, two for each gear. The package therefore contains a complete set of 6 pieces.
