Aluminum Spiral High Speed Door
The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.
Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.

For precision industrial applications, Seiko has developed a long-life single-row radial thrust ball bearing "High-performance radial thrust ball bearing for industrial pumps", which was launched on June 14, 2007. Increased load capacity and lubricity, and life expectancy increased by approximately 50% compared to the company's original products. It is planned to exhibit the "Mechanical Element Technology Exhibition" (Tokyo Ariake International Convention and Exhibition Center) held on June 27-29, 2007.
The internal design has been optimized to increase the basic dynamic load rating ratio of approximately 13%. In this way, since the life of the bearing of the same size is extended by 1.5 times, the maintenance interval of the industrial pump can be increased, and the running cost can be reduced. In addition, the industrial pump can be miniaturized and energy-saving by using a smaller bearing without changing the set life.
In addition, in order to improve the lubricity, a copper alloy is used in the bearing cage, and the shape and the guiding manner are improved on the basis of this. Due to the expansion of the internal space of the bearing, the inflow/discharge of the lubricating oil is improved, so that the temperature rise of the bearing can be reduced by about 7% - by about 4 ° C. This helps to increase the reliability of industrial pumps.
In addition, the operability when assembled into an industrial pump is also improved. Thereby, the positioning accuracy of the industrial pump blade can be more easily ensured. The price is negotiable.
