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.

The spherical bearing with a seat is a kind of bearing unit that connects the rolling bearing with the bearing seat. Most of the special spherical bearings are made of spherical surface with outer diameter; together with the bearing housing with spherical inner hole; Generality and interchangeability. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Together; these bearings also have a certain degree of alignment in the depiction; easy equipment; sealing equipment with two layers; can work in harsh environments. The bearing housing is usually cast and cast. The common seat has a vertical seat (P) Square seat (F), boss square seat (FS), boss circular seat (FC), diamond seat (FL), ring seat (C), slider seat, etc. (T).
There are two common types of outer spherical bearings:
l Outer spherical UC bearing with set screw,
2 outer spherical UK bearing with tapered bore,
The spherical bearing with seat is divided into the bearing core and the bearing seat; in the name of the bearing core plus the bearing seat; for example, the spherical bearing UC205 with the set screw is equipped with the vertical seat UCP205. The spherical bearing with the seat has Very interchangeable; the bearing core can be assembled freely in a bearing housing of the same standard.
