Zylinderrohr als Zylinderhülse in Modellbaumotoren mit hoher Verschleißfestigkeit

Cylinder tube

This tube is a hydraulic cylinder tube. The inside of the tube is very dimensionally stable and wear-resistant. The cylinder tube is suitable as a cylinder sleeve for an internal combustion engine or flame eater. We also use this cylinder tube in our models. We use it for the combustion engine Karl, Stirling engine "Big Laura" and the Flame Eater Jarne. Due to its high wear resistance, the tube has proven itself as a cylinder sleeve for us.

Piston rings

Piston rings for installation in an internal combustion engine. These piston rings are industrially manufactured and fit exactly into the cylinder tubes we offer. The rings are made from GG 25. Because they have a larger diameter when dismantled, they always rest against the cylinder wall when assembled due to the spring force, thus ensuring good compression. These piston rings fit perfectly into our cylinder barrel. Dimensions of the piston rings 25mm Nominal diameter: 25 mm Height: 1.5 mm Thickness 1.05 mm Material: GG25 Dimensions of the piston rings 30mm Nominal diameter: 30 mm Height: 1.5 mm Thickness 1.5 mm Material: GG25 Dimensions of the piston rings 40mm Nominal diameter: 40 mm Height: 2.0 mm Thickness 1.7 mm Material: GG25

Geschälte Grauguss Rundstange für Kolben im Modellbau

Cast iron round material

Cast iron with lamellar graphite. The surface is peeled on the gray cast iron bars. The round bars are a little over-sized. You can also make a 30mm piston with a 30mm diameter. The material is suitable both for the production of pistons or cylindrical sleeves for model-built motors as well as for the production of plain bearing bushes. We use this material for the pistons at the station "Karl". The round material can be perfectly machined on the lathe and on the milling machine and has excellent running characteristics. All round bars are 300mm long.
