These high quality 8mm steel bushings are made from porous sintered steel in combination with graphite. This type of porous metal can absorb oil and grease, greatly reducing the need for maintenance and lubrication.
Unlike stainless steel or other full metal bearings, the risk of surface grinding or burning on the gear axles has also been greatly reduced, minimizing damage to the expensive gears compared to the bushings. Dimensions have been optimized to easily fit almost any 8mm gearbox without being too loose or damaging the holes during installation.
These bushings are ideal for specific airsoft builds where the main priorities are durability, strength and ease of maintenance.
