Here are a few simple identification methods, not absolute, for reference only:
1- slide rail system has now become the standard scheme in linear motion. Specially developed for high-precision applications, such as machine tool industry. However, more rail guiding systems do not require high rigidity and high guiding accuracy. ELINE products from bosch rexroth are especially suitable for manufacturing, transportation and positioning of light machinery. In these applications, the emphasis is on economy and durability. It consists of aluminum alloy slider and guide rail with ball raceway, which is made of quenched bearing steel. It is characterized by light weight, compact structure and the same bearing capacity in four main bearing directions.
Double slider
The unpolished part of the upper surface of the slider in the early stage is black, and the product in the later stage is shot peened metallic color. A-type slider has laser etched silver lettering and guide rail section pattern logo on the non-polished part of the upper surface, and the trademark logo of B-type slider is on the side. Imitation text or pattern lines are thick and slightly blurred. In addition, only one side of the genuine sliding cover is the reference surface (polished), while most imitations are polished on both sides.
3- Slip feeling
Authentic sliding resistance feels even and sluggish, while imitations feel brittle when sliding, and poor lubrication has the feeling of sliding friction rather than rolling friction.
4- Packaging
Outer packing: The genuine outer packing is a cardboard box or wooden box with a capital "Shangyin" sign on the outer surface, but this is a common situation, because there are many agents of Shangyin, and cross-shipment is serious, and some agents use other packaging materials because of insufficient packaging materials.
