Key features of Specna Arms 8 mm bearings

Ball bearing construction

Unlike solid bushings, these bearings use a ball bearing mechanism to provide rotational support for the gear shafts inside the gearbox.

8 mm diameter

For 3mm gear shafts

The inner diameter is designed for gear shafts with a diameter of 3 mm. When combining parts from different manufacturers, make sure to check this dimension as well.

Steel construction

The bearings are made of steel and are intended as replacement or service parts for the drivetrain of an AEG.

Complete set of 6

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 bearings fit every AEG gearbox?

No. The gearbox must have holes designed for 8mm bearings. Gears with 3 mm diameter shafts must also be used.

How many bearings do I need for one gearbox?

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