Teflon axle washer, size 12x6.35x0.4mm. Designed for installation on the axial assembly of a folding knife. It can be used both independently and as a lining under the bearing. Washer dimensions - outer diameter 12mm, inner diameter 6mm and thickness 0.4mm. The kit includes two washers.
Teflon (Teflon) - polytetrafluoroethylene, known in the post-Soviet space as Ftoroplast-4. This fluorine-containing plastic, obtained by polymerization of tetrafluoroethylene in the form of a white powder, is pressed at high temperature into products of the desired shape. The main advantage of Teflon is its high resistance to almost any chemical attack and low coefficient of friction. In fact, the use of Teflon as an anti-friction material is one of its widest applications. With dry friction of metal on fluoroplastic-4, at a low sliding speed, the friction coefficient is so small that it usually does not exceed the normal friction coefficients in metal bearings in the presence of lubrication! Products made of PTFE are resistant to deformation even under the influence of high temperature. The main advantage of using Teflon as washers for knives is the soft and smooth running of the blade. Like metal washers, Teflon washers need lubrication and regular cleaning from dust and dirt to function properly.
