Is heavy rail really able to bear weight?

Three heavy duty ball rails load from 225kg to 60kg, Series 76 can hold 225kg with locking device, Series 57 and 53 can hold 115kg, Series 51 can hold 60kg.
Heavy-duty slide rails are characterized by full-display and high load bearing, which are used in machinery, automobiles, cabinets, electronics, rail transportation, ATM, military systems and other fields.
The pull out travel of the three-section slide rail is generally proportional to the closed length, for example, the travel of the three-section slide rail 450mm long is also about 450mm. There are also a small number of customers require that the pull out travel of three slides is longer than the normal pull out travel of the slide. Lianli can meet the requirements of customers, but the pull out travel of the slide is within a reasonable range. The longest pull out travel of the slide can only be 150mm (6 inches) longer than the closed length, and the quality and bearing capacity of the slide will be affected if it exceeds this size. The effect is not as good as the normal pull.
