LED manufacturing is complex and high-tech. In this process, as long as one link goes wrong, LED Lamp Beads will lose their quality performance. In the whole process, the same batch of raw materials will have different quality of packaged products due to non-process reasons in the production process, which cannot be distinguished from the outside; In-Line Led Lights,In-Ine Led Lamp Beads,In Line Led Lamp Beads 3Mm,3Mm Double Color Led Dongguan XINYUDA Technology Co., Ltd. , https://www.gdxige.com

Rolling SKF bearings are a lot of mechanical parts produced; and the precision of production is very strict; the degree of specialization in technology is very high; therefore, for most types of SKF bearings that are simply bought; it should be more cost-effective than purchasing; Under the following conditions; consider the correction problem of SKF bearings; namely: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
(1) Many of the same types of SKF bearings used in large factories; the failure modes are mainly the wear of the tumbling surface; fatigue or fretting abrasion; especially the damaged parts are mostly cages or tumbling bodies; and the ferrules or gaskets still have Revise the value,
(2) Large and extra large SKF bearings; close to failure or failure, but the parts have not been seriously damaged; or valuable SKF bearings need to try to extend their useful period of use,
(3) Some types of SKF bearings that are difficult to purchase; have no spare parts after failure and have to be repaired; especially imported SKF bearings,
(4) SKF bearings have minor damage; for example, fine rust that occurs during the inventory period; and subtle fretting abrasions that occur during the transportation process; such corrections are simple and a pity.
Recommend to friends comments close window Bearing related knowledge The matters that should be paid attention to when packaging bearings are to analyze the annealing process of high carbon chromium bearing steel. The correct protection of the universal joint cross shaft needle bearing. The method of selecting the data according to the service life and reliability requirements of FAG bearing.

The packaged lamp beads are filtered into different quality lamp beads through light separation. These lamp beads are basically sold by price difference. The defective products can be sold by weight. This phenomenon in the LED market leads to a large difference in the price of LED lamp products.
Parameter relationship of white light bulb:
The basic photoelectric parameters, such as light flux, light intensity, illumination, brightness (brightness), radiation power, color temperature, color rendering, etc., will not be introduced here. We need to focus on the relationship between these parameters.
The quality identification of LED lamp beads requires spectral analysis and photoelectric analysis. If the quality requirements are strict, it also needs to pass the LM79 and LM80 tests. The manufacturer needs to complete the LED Lamp Bead quality evaluation before mass production. The seller must require the manufacturer to provide the LED lamp bead quality evaluation report to provide the commitment to customers.
