1. Whether the outer packaging can be clearly defined; the factory brand has a special depiction of the external packaging; and the factory that produces the production conditions is manufactured; therefore, the packaging is clear from line to color; unambiguous . /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2. Can the steel printing be clearly printed on the FAG imported bearing body with the brand name, label, etc. The font is very.

3. Can you have a left-handed grip on the FAG bearing body sleeve with your left hand; turn the jacket with your right hand to make it rotate; listen to its noise, because the production conditions of most counterfeit products are backward; thoroughly craft workshop operation; inevitably in the production process It will be mixed with impurities such as sand; it will be hidden in the FAG bearing body; therefore, the noise will be announced during the rotation. This is the biggest difference between the strict implementation of the production specifications and the operation of the factory brand.
4. Whether the appearance of dirty oil traces should be uniquely noted when purchasing FAG bearings. Because the current domestic anti-rust skills are not unique to the home; so the rust-proof treatment of the bearing body is very simple to leave a thick trace of oil; Sticky and sticky on the hand; foreign imported bearings can not see the traces of anti-rust oil; but it is a unique and careful expert said that the imported bearings smell a smell; definitely the anti-rust oil; just look Not enough.
5. Whether the chamfer can evenly chamfer the so-called FAG imported bearings; that is, the intersection of the horizontal and vertical faces; the counterfeit FAG bearings are constrained by the production skills; the corners of these corners are not handled satisfactorily.

The rubber soft joint products take advantage of the advantages of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. High pressure, high temperature mold vulcanization. It has high internal density, can withstand high pressure, and has good elastic deformation effect. Shock absorption, noise reduction, lightweight, non-toxic.
According to the shape, it is divided into: concentric and same diameter, concentric reducer, eccentric reducer.
According to the structure, it is divided into: single sphere, double sphere, elbow sphere.
According to the connection form, it is divided into: flange connection, threaded connection, threaded pipe flange connection.
Flange for connecting rubber joint: DIN BS ANSI JIS standard
Working pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa
Working temperature: -40 degrees to 80 degrees (also can process high temperature resistant rubber soft joints)
Material of main parts
Ball body: natural rubber, neoprene, butyl rubber, nitrile rubber, fluorine rubber, EPDM
Inner and outer lining: natural rubber, neoprene, butyl rubber, nitrile rubber, fluororubber, EPDM, PTFE
Main Frame: Nylon Cord Flange: Cast, Forged Carbon Steel (Q235), Stainless Steel (201, 304, 316, 321), Plastic (PVC, PPC)
The flexible rubber soft joint solves the problem of different diameters when connecting metal pipes, and also has the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It is used in connection with pumps and Valves, pipelines with large vibration, and pipelines with frequent changes in cold and heat.
Rubber soft joint products have high pressure resistance, good elasticity (axial and lateral angular displacement), noise reduction, light weight, shock absorption, easy installation, flexible use, easy replacement and maintenance, and have acid resistance, alkali resistance, oil resistance, etc. Features.
Can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other pipeline systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -15℃~120℃. The special type is used to transport the above-mentioned medium or oil, concentrated acid and alkali, and solid materials above -30℃~250℃.
Applicable media: sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
When using or storing the flexible rubber joint, avoid high temperature, ozone, oil and acid-base environment. A sunshade frame should be built for pipes used outdoors or facing the sun and wind, and it is strictly forbidden to expose to the sun, rain, and wind erosion. The surface of the joint is strictly prohibited to be painted and wrapped with thermal insulation materials. Due to the aging problem of rubber products, it should be checked and replaced in time.
