A&K High-Strength Open Steel Bearings Bushings (8mm OD x 3mm ID)

Description

A&K open steel bushings are internal gearbox parts for airsoft electric guns, made to replace the standard polymer or soft brass items found in many factory builds. Each one measures 8mm on the outside and 3mm on the inside, so they fit 8mm gearbox shells and carry the gear shafts in place.

The open profile leaves the bearing surface exposed, which lets lubricant reach the shaft continuously rather than sitting behind a seal. The bodies are made from a high-tensile, wear-resistant steel alloy, chosen to hold up in high-stress setups and heavy spring loads where softer materials may deform.

Supplied as an upgrade kit for workshop use, the A&K bushings suit technicians servicing or rebuilding AEG gearboxes, and stockists keeping internal upgrade parts on the shelf.
