The data analysis of the rolling bearing is as follows: the ferrule and the rolling body of the rolling bearing; one side repeatedly receives the high touch pressure; one side carries the tumbling touch with the sliding. The adherer; one side and the ferrule and the rolling body are both sides; or one of them slides Touch; one side receives tension and compression. Therefore; the ferrule of the bearing; the information, function, and primary requirements of the roll and the holder are as follows.
The functions required by the ferrule and roll body data: high rolling fatigue strength, high hardness, high wear resistance, and the functions required by the frame data: good dimensional stability, high mechanical strength, and also good processing. It is not the same in use; it is also required to have good impact resistance, heat resistance and corrosion resistance.
Information on ferrules and tumbling bodies: ferrules and tumbling bodies are usually made of high-carbon chrome bearing steel. Most of the bearings; using JUJ steel in the JIS steel grade. The large-sized bearings use the chemical composition of SUJ3.SUJ2; in various countries around the world; as bearings The data has been normalized. For example, it is the same kind of steel as AISL52100 (USA), DIN100Cr6 (West Germany), BS535A99 (UK).
Further demand for impact resistance; use of chrome steel, chrome molybdenum steel, nickel chrome molybdenum steel as the bearing data, quenching by carburizing; make the steel from the appearance to the appropriate depth has a hardened layer. With appropriate hardening depth, fine Arrangement, suitable for the appearance of hardness and the hardness of the carburizing bearing; the bearing has better impact resistance than the bearing bearing steel; the chemical composition of the steel for ordinary carburizing bearings.
Vacuum degassing was implemented; therefore; the data used were high in cleanliness, low in oxygen content, and good in quality. The appropriate heat treatment was selected; the life of the rolling tumbling of the bearing was significantly improved.
In addition to the above steel grades; based on special use; also use high-speed steel with excellent heat resistance; stainless steel with good corrosion resistance.
Persistence of information: stamping and holding materials; using low-carbon steel. It is not the same as the use; also using brass plates, stainless steel plates. Cutting the data of the frame; using high-strength brass, carbon steel; Use synthetic resin.

Industrial Sectional Door

Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.

The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).

Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.

Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).

Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
