B. When the oil is smooth; according to the condition of the slider device; sometimes the oil can not reach the track. In case of such a situation; please negotiate with NSK.
.2) Assemble A. The sliders of the interchangeable products (that is, the products that the rails and sliders can match) are supplied on the temporary shaft. For this purpose; when combined with the guide rail; please pay attention.
B. If the private line is dismantled, it will incur the entry of dust or reduce the accuracy of the combination of parts; for this reason; if it is not a last resort; please do not open it easily.
C. Sometimes it is only necessary to tilt the rail; the slider will move; so this should be done not to let the slider fall off the rail.
D. The specification end cap is made of plastic. If you hit it hard or bump it; it will damage it; therefore, pay attention to it.
.3) Matters A in application. When using; please try to prevent the entry of dust or foreign matter.
B. Please set the operating temperature limit below 80 degrees (except for the heat-resistant standard products). Beyond this temperature; plastic end caps can be damaged.
C. When the customer cuts off the guide rails personally; after cutting off, completely remove the burrs and curled edges of the cut surface.
D. When the slider is in the reverse hanging condition (for example, when it is fixed on the ceiling and the slider is facing downward); if one end of the cover is damaged; the ball will roll out; causing the slider to fall off the guide rail. Regarding this kind of use; please adopt the corresponding method such as additional safety equipment beforehand.
.4) Storage If the guide rails are placed in a bad condition, the guide rails will be deformed. When in custody; place it on the appropriate plane; stick to the horizontal position.

The definition and classification of engineering plastics is a specific name.Engineering plastics broadly refers to plastic which has high performance and may replace metal materials.The narrow sense refers to the strength and heat resistance of plastic (PE, PP, PVC, ABS, etc.), which can be used as a structural material for industrial use and has the functional structure of high performance plastic
Plastic can be divided into two main categories: thermoplastic (after heating and melting) and thermosetting (after heating and turning into a three-dimensional structure).Engineering plastics can also be divided into special engineering plastics and standardengineering plastics.
The so-called engineering plastics plastics often refer to thermoplastic polyamide (PA plastics).Polyoxymethylene (POM plastics), polycarbonate (PC plastics) and so on , and special engineering plastics often refers to other than the above five kinds of more excellent performance engineering plastics.According to the using temperature points, generally use temperature at 150 ℃.The following is a standard engineering plastics (generally is 100 ℃--150 ℃), more than 150 ℃ for special engineering plastics, special engineering plastics is divided into 150 --250 ℃ class (including the standardengineering plastic compounds) and above 250 ℃.The higher the temperature, the higher the price.
Characteristics of engineering plastics(compared with metal materials):
1.Advantages:
(a) small proportion: 1.0 -- 2.0, about one sixth of iron, reducing the weight effect;
(b) good processing and high production efficiency;
(c) water resistance and chemical corrosion;
(d) the friction coefficient
(e) can be colored freely;
(f) easy to compound with Glass Fiber and various filler;
(g) excellent electrical insulation;
(h) excellent heat insulation, with thermal conductivity of about 1% of iron and less than two thousandths of copper;
(I) reduce costs, save resources and energy.
2.Disadvantages:
(a) low heat resistance and low softening point;
(b) the mechanical strength is low and the tensile strength is generally about one-tenth of the steel;
(c) the dimension stability is poor and the linear expansion coefficient is about five times that of steel;
(d) poor durability. Prolonged exposure to gravity is susceptible to fatigue, and prolonged exposure to ultraviolet radiation is associated with lower performance.
3. Application of engineering plastics
(a)One is the functional components of strength, drug resistance, abrasion resistance and other requirements.The other is mechanical parts with shrinkage, dimension accuracy and appearance.Generally speaking: the former is crystalline engineering plastics, the latter is non-crystalline engineering plastics.The practical application often requires the performance of both.Engineering plastics with glass fiber (GF) or carbon fiber (CF) are more suitable for such requirements.
(b). More than half of the applications in engineering plastics are automotive and electronic, while the main use of standard plastics is extrusion molding (51%) and non-industrial products (21%).
