The axial fastening of the bearing includes axial positioning and axial fixing. In order to avoid the bearing moving on the shaft and in the bearing housing hole; the inner ring of the bearing needs to be fastened on the shaft, and the outer ring must be fastened to the bearing housing. Inside the hole (or inside the cup). The inner and outer rings of the bearing are required to be axially fastened in both directions; or axially; depending on the limit requirements of the bearing and the type of bearing used.
In the two-way limit bearing (ie fixed support); the inner ring of the bearing is on the shaft; the outer ring must be axially fastened in both directions in the bearing housing hole. In the one-way limit support; it is necessary to transmit force The opposite direction applies a one-way axial fastening to the inner and outer ring. If the non-fractional bearing is used for the swimming support; only the inner ring is axially fastened to the shaft; the outer ring is opposite to the seat hole. Self-propelled axial movement, when the inner and outer rings are divided into radial bearings for swimming support; then the inner and outer rings are required to be axially fastened in the shaft and in the seat hole; the inner and outer rings of the bearing Relative axial travel.
The axial positioning of the bearing is usually the shoulder positioning of the inner ring and the shoulder positioning of the bearing ring (or cup). In order to ensure the positioning effect of the shoulder and the shoulder; the shoulder and the shoulder should be The end faces of the inner and outer rings of the bearing are tightly attached. The height of the shoulder and the shoulder should also be selected according to the specifications. 庋 pure kill V ざㄎ 慷 慷 阌谧 阌谧 阌谧 阌谧.
The fixing method of the inner and outer rings of the bearing should correspond to the force transmission.

At present, waterproof roof coating and Bridge Deck Waterproofing mostly use a combination of polyurethane waterproof coating and waterproofing membrane. Although it can achieve a certain waterproof effect, there are still many problems.


UMS-AUPT polyurea elastomer waterproof coating replaces other traditional waterproof layer, not only solves the problem of poor adhesion between polyurethane waterproof coating and waterproofing membrane, lap joint between coils, sealing of waterproof coating and long construction period And technical problems such as environmental pollution caused by waterproof coatings during construction.


The Roof Waterproof Coating and bridge preservation waterproof. And UMS-AUPT brushed polyurea waterproof coating system can be used to complete the durable waterproofing easily and efficiently.


UMS-AUPT polyurea elastomer waterproof coating has excellent performance:

1. It has strong adhesion, can be attached to almost any substrate and is easy to apply. It can be used on different substrates such as concrete, metal, wood and plastic.

2. UMS-AUPT brushed polyurea elastomer jointless coating system for Waterproof Roof , the tensile strength is large, and the most chaotic parts such as roof margin, skylight and air conditioning well can also be used.

3. The construction speed is fast, the whole waterproof layer can be integrated into one body, completely preventing the immersion of harmful media, and greatly prolonging the service life of the concrete structure.

4. It has good weather resistance, excellent UV resistance, high process tolerance in outdoor low temperature environment, and can close concrete cracks up to 10 mm.

5. Good environmental adaptability, no VOS emission during construction, and solve technical problems such as environmental pollution during construction.


The two majestic constructions of Astana, the new capital of the Republic of Kazakhstan, are excellent, for example, including the largest mosque in Central Asia. This magnificent building can accommodate more than 5,000 people in the main hall, the dome is 40 meters high, and there are four minarets. Polyurea Roof Coating, which can taste the cold test of minus 50 °C.


A similar solution was chosen for the opening and closing of the Astana Stadium. The stadium covers an area of 10,000 square meters and can accommodate more than 30,000 spectators. The two special construction projects are intended to be a complete success, and it is abundantly proven that polyurea coatings can remain stable even under extreme climatic conditions, and this coating system will continue to open up new uses.
