Seiko Co., Ltd. develops "wheel bearing with high reliability seal ring" and strives to achieve sales of 4 billion yuan
Construction Hoist Steel Structure
Construction Hoist Steel Structure means the construction hoist spare parts like Construction Hoist Mast Section, Passenger Hoist Cage, Construction Hoist Wall Tie and so on.
The length of each mast section is 1508mm, the rack is fixed on the mast by three bolts and it can be exchanged. For the single cage hoist there is only one rack on the mast section, and the mast section can be used for the double cages hoist by increasing one rack. The section of the mast is diverse, select one type section according to different hoist. The mast sections are bolted together with M24 bolts and nuts to form mast. The mast is tied to the building with tie-in and is the guide rail of the cage. According to the user`s or circumstance`s request, surface of mast is hot dip galvanized, which can prevent it rusting.
The tie-in(wall tie) is the linked part between mast and building, to keep the stabilization of the mast. Distance between the tie-in is about 6~9m alone the mast. There are several types of tie-in. Select one of them according to need, tie-in can adjust the vertical of mast in definite ranges. According to the user`s or circumstance`s request, surface of the tie-in is hot dip galvanized, which can prevent it rusting.
The cage dimension(L×W×H)(m): 3×1.5×2.5. We can also manufacture cages of other size according to the user`s needs. The material of the cage and the door material can be steel wire weave, aluminum-plastic panel, punched-plate, figured aluminum board or other type according to user`s needs. The gate is equipped with drawing gate,include small turn over gate.

Seiko Co., Ltd. has been selling high-water-resistant “high-seal ring†bearings in emerging markets and other world markets. Hub bearings are usually mounted on the vehicle in the position closest to the road surface, and are easily stained with muddy water. They are also important parts supporting the vehicle body and therefore require high reliability.
Especially in Russia and other regions, there are unique bad road conditions due to the low-temperature environment. Snow, ice, frost, and mud on unpaved roads will continuously enter the hub bearings. Therefore, the ability of the hub bearings to resist mud is higher than that of high seals. Circle money. In addition, in emerging market countries, with the promotion of environmental protection initiatives in recent years, there are CO2 emission reduction requirements, and gasoline prices are also rising, and improving the fuel efficiency of automobiles has become a top priority. Therefore, wheel hub bearings are required to improve reliability while reducing friction. .
Japan Seiko added an auxiliary lip to the outside of the current main lip by changing the cross-sectional shape of the seal ring to prevent mud penetration and hinder lip movement. In this way, we achieved 1.5 times the original mud resistance. Since the space outside the accessory lip is narrower than the space outside the current primary lip, space for storing muddy water can be reduced, making it difficult for muddy water to accumulate.
Since the size of the new seal ring is controlled to the same degree as the original high seal ring, a highly reliable seal ring can be used without changing the size of the hub bearing. In addition, the surface pressure distribution of the lip of the seal ring was also optimized through computer analysis. Thus, after the auxiliary lip is added, the sliding friction of the entire seal ring will not be greatly increased. With the above improvements, the friction loss equivalent to that of the original hub bearing is achieved.
