And our designer also choose to use mini hexagonal screws (note: special tools must be used for unscrewing), chocks, and equipped with excellent lubrication system. The flywheel is made of SUS304 and electrophoresed into a classic red. (the height of the spindle can be reduced after removing chocks).The engine consists of precision casting produced shape parts each carefully made with excellent surface finish & dimensional accuracy and checked to ensure reliability in service. Surface electrophoresis treatment does not fall off for a long time. The surface electrophoresis will make not fade and tarnish over time easily, and keep its initial luster and brightness. The spindle sleeve is made of high-hardness beryllium copper, which is resistant to friction and guarantees long-term operation.
The crankshaft is essentially the backbone of steam engine. After 300-times trial, the intergrated crankshaft is finnally machined for this model steam engine, which provides good stability & strength, high concentricity. Oil cup made of brass with M60.5 or 1/4-40 connection thread. The oil quantity is adjustable on these oilers via the knob.
The through hole is 1.2 mm in diameter. The speed of the flow depends on the viscosity of the oil.
A drain is at the bottom of the oil cup. And every lubrication ports are provided for each friction surface. Every joint surface is sealed with fluorine rubber ring, which is are not susceptible to the corrosion and high temperature. Suitable for 60cm+ Steam Boat. It supports positive and negative rotation.It can provide much more power for its large cylinder diameter and large stroke. Efficient boiler is recommended to be used together to guaranted the high power. Note: Boiler is not included. It's a a perfect surprise gift for steam boat engine model lovers not only because of its mini delicate mechanical handicraft, but also collection value. People who receive it will regard it as a treasure. Every steam engine will be coated with anti-rust oil before leaving the factory to prevent rust. If it is not coated with anti-rust oil, sweaty hands can easily make it rust. Please note that any boiler cannot support long-term operation. The air pressure in the video is 0.8MPA. We do not recommend running for a long time under 0.8MPA, because the wear of the friction surface is inevitable. After connecting the boiler (the pressure is 0.2-0.4MPA), as long as the lubrication is in good place, there is no need to worry about long-term operation, because we have strengthened the main connection points and made a plug-in structure. The main oil cup lubricates the cylinder. Please lubricate each joint in advance before starting to prolong the service life of the machine. Ground Clearance of Spindle Center: 19.0mm. Operating Pressure: 0.1Mpa - 0.8Mpa. Air Pressure Recommended: 0.4Mpa - 0.6Mpa. Intake Connection Thread: M6-0.5 1/4-40. Base: 58mm wide, 48mm long and 110mm high. Product Size: 4.8 x 5.8 x 11cm.
